Hi,
yesterady I recieved my XDA IIs and a THB handsfree cradle for it.
As I noticed that the THB device is only Mono ( the TEl-In at my car stereo is mono too :-() I decided to do a littele modification today. I added a wire for the CAR_AUDIO_R to the connector and added a stereo-out to the THB cradle that now goes into the AUX of my car stereo.
I also added a switch to switch from "normal handsfree" mode to "just AUX" mode. The switch disconnects the IN_CALL, Analog GND and the CAR_AUDIO_L from the THB handsfreeset and connects it to the stereo-out (that is already connected to the CAR_AUDIO_R) I added.
I installed the special wavedev.dll that THB offers so every sound is redirected to the 22 pin connector if the XDA is in the THB cradle.
So far it works as I expected:
If I switch the switch, the radio is not muted anymore when the XDA produces a sound and I can here MP3s in stereo via my aux-in on the car stereo.
The downside:
The audio quality !!! - the signal that comes from the 22 pin connector seems to be pretty poor. I already installed the BASSBOOST plugin (which did improve the bass) but compared to my brothers pretty cheap PNA the sound still is pretty poor.
So my questions:
Any hints to improve the sound?
Are there any software issues (I am not sure what ROM i use ATM because I first wanted to get the HW part running _ is is some unmodified O2 UK ROM).
Are there any hardware improvments I can make here ( I saw that the homebrew Car kit in the wiki part does not just connect the audio pins but adds some electronics there- can that help or delivers the CAR_AUDIO_L/R bad quality in general ?!
Thank you for your help.
Let me know if what additional information can be usefull here and sorry for my english.
Best regards
P.S.: I am looking for the quality because my initial plan was to add also an ASUS WL-HDD with all my music on to get rid of burning CDs and be able to copy the music I want to hear from my desk direct into my car via WLAN.
Hi
The bad audio quality problem was talked about many times in past.
Still, there's no solution. Simply, the bottom connector audio out is designed for GSM Voice only. THB modified wavedev.dll to route all audio to bottom connector.
That's useful for eg. sat-nav, but not for high quality music.
Another problem that ocurred in my BlueAngel during DIY car-kit research, was the IN_CALL signal.
My BA doesn't provide +5V on IN_CALL ever ! Regardless of phone state, CAR_ON state etc...
Unfortunately, I don't have an original THB carkit to test my BA on.
I'm not sure if my BA's IN_CALL signal is dead or something else's wrong :/
Can You at least tell me what ROM version do you use in your BA ?

I'm sick of trying to find a car cradle that has audio out, ps2 and 12v for charging!
Why is it that no manufacturers of xda cradles ever realise that some of us want to listen to mp3's in the car and have tom-tom voice prompts coming through our stereos!
Being right handed, I want my PDA on the right of the steering wheel, so I can operate Tom-Tom before setting off, or change tracks on media player. I did look at the Brodit pro-clip solutions, but they all seem to be for the centre console for my car (a citroen AX)
I've discovered that the driver's side vent mount has a removable panel, which means I can easily mount a small piece of wood (effectively a small flat shelf) for mounting a cradle, this also brings the device out of the reflective glare zone in the windscreen during night driving. It also means all I need is a standard xda iis cradle to do this mod.
So with much careful thought I've decided to do the following:
Buy a spare cradle:
http://www.my-xda.com/xda2s_other.html
Which leads me to the next question....
Has anyone got any modding experience with the xda2/xdaiis cradle?
similar to this old posting for the Wallaby...
http://forum.xda-developers.com/viewtopic.php?t=256&highlight=cradle
(although I couldnt see any of the images on this old posting!)
In theory, this project has 3 key issues to resolve...
1) Powering the cradle and Bluetooth GPS
Three options seem to be available...
a) The hobbyist approach...I've seen various "car-kit diagrams" like this one,
http://forum.xda-developers.com/files/xda_car_kit_circuit.jpg
but to be honest I have no pcb making experience.
b) 12V to 5dc cigarette socket transformer adapter to provide power to the cradle, and perhaps to the bluetooth gps for charging. This should be easier to achieve!
Anyone have any links for low cost solutions for this, obviously it would need to convert 12VDC to 5DC at 2-3Amps
c) As the xdaiis usb cradle charges directly from a USB power source, this seems an Ideal solution!
http://www.expansys.com/product.asp?code=EXP_USB-CLA
2) Audio out: THE MAIN PROBLEM!
Ideally I just want to get in the car and cradle the device, no other connections being required.
Therefore I need to modify the xdaiis cradle for audio output...
Ideally, the feed for the audio should come from the bottom connector, when the xdaiis is cradled.
With this in mind, I found this article about dismantling an xdaii cradle...
http://en.pdamobiz.com/en/forum/forum_posts.asp?TID=42&PN=1
If you look at the images on this web-page, you can see that - at the back of the cradle on the opposite side of the usb cable from the 5volt dc input is what looks like a pcb pinout for a headphone connector...
is this right? Can anyone confirm this.
Would it be possible to solder a connector onto here (assuming the solder pads connect to the 22pin connector!)
As this would be far easier than mucking about trying to solder onto the miniscule pins on the bottom of the 22pin connector on the cradle as it goes into the pcb!
If it works of course!
b) modify a headset
I did consider modifying an old wallaby headset to wire it into my car amp
http://wiki.xda-developers.com/wiki/Connectors , does anyone have any info on the pinout for the himalaya/blue angel headphone socket? I have also tried a friend's xda II headset on the IIs and yet again they have changed the pinout! The audio connections are once again totally different, resulting in the "echoing" effect when one headset is plugged in from the other device. This means that the audio ground pin has changed since the xdaII headphone socket schematic! This difference is also confirmed by looking at the handsfree "pod" on both headsets... The IIs has one button for answering a call, where the II has two buttons, wether it is the same as the XDA1 (Wallaby) remains to be seen....
c) buy a PDA2k 3.5mm headphone adapter...
http://www.expansys.com/product.asp?code=118289&sbadd=118289
Then use a standard lead to connect it to the hi-fi amp in the car.
3) charging the TOM TOM BLUETOOTH GPS
I'm wary of putting anything other than the recommended voltage (5VDC) into this device, so the best option is to supply power using (1b) or (1c) above, perhaps cutting into the supplied RJ cable to minijack psu to hook it up from the same supply.
While I'm on the subject of the bluetooth gps.... Does anyone knopw how long does the tom tom bluetooth gps work with a full charge?
Does it vary based on an active connection, or is it the same as on standby?
Do I need to power it in the car at all? Can I not just charge it as required at home? There doesnt seem to be much literature about the Bluetooth GPS reciever's battery life in the box!
Anyone care to comment on these ideas?
:lol: :lol:
I think the fact that no-one makes a cradle which provides audio-out through the bottom connector of the XDA2 is because the XDA2 doesn't provide this possibility. It's not the car-kit manufacturers' fault. Blame HTC.
However, I could be wrong... :roll:
My solution: I bought one of these XDA2 mounts ( http://www.pdamods.com/proddetail.asp?prod=A11XDA2MNT&cat=23 ) which works really well. It charges the phone and my TomTom BT GPS. To achieve audio-out I plan (eventually) to use the XDA2's headphone socket by drilling a hole through the mount's base in the right spot and using a 2.5mm jack adapted to play through the car stereo. Not an ideal solution, but surely must be simpler for you than trying to build a reliable (and safe!) 12V -> 5V convertor and butchering a spare XDA2 desktop cradle?
Just a suggestion... 8) Let us know how you get on. Good luck!
QUOTE 12V to 5dc cigarette socket transformer adapter to provide power to the cradle, and perhaps to the bluetooth gps for charging. This should be easier to achieve!
Anyone have any links for low cost solutions for this, obviously it would need to convert 12VDC to 5DC at 2-3Amps
Just about any mobile phone car charger will do.
Silicon s, you must be wrong :lol:

That's what I'm looking for. Have you found anywhere to actually buy them? I looked over the whole site.
How about this alternative cradle. I bought one for my XDAIIs and it works perfectly. Got one for the birds XDA2 and that work great too.
It provides power to either a wired GPS or charges a bluetooth GPS, it has a built in speaker and a cables provided to run from the XDA's headphone socket to the cradle. THIS THING IS LOUD!
One word of caution, the speakers in my car are shielded so I don't get that warning noise from them that I am about to get a call or text. The speaker on the cradle is NOT shielded and so you do get interference when you are about to get a call or switch cells.

i thought about using my 6601 as an MP3 player in my car as well. but since my eclipse cdplayer does mp3, i abandoned the idea
option 1: cut up a 2.5mm headset and plug it into the top of the device
pros: cheap and effective
cons: have to plug it in every time (and unplug it to take a call)
option 2: pair a bluetooth headset with the device, crack it open and wire the speaker to a preamp
pros: wireless
cons: ruin an otherwise good bt headset, music would be in mono
option 3:
http://motorola.digitalriver.com/se...e&SiteID=motostor&productID=36065700&Env=BASE
"transfer audio to hands-free"
pros: wireless
cons: EXPENSIVE, pretty vague description
option 4:
http://www.itechdynamic.com/html/border22.htm
http://xprnnews.xfn.info/itech/nightingaleBSH338/en.htm
pros: wireless, stereo, routes incoming cails through car
cons: i cant find it anywhere
its called the "nightingale BSH338" or the "Bluetooth Stereo Clip Headset"
if anyone finds one, please reply with a link
ok i did some more reading on the subject and i found this (page 2 of the forum)

After thb introduced their first 'real' blueangel carkit, could this be the second ? I prefer this one because you don't have to connect a wire, but have a real cradle. The gps is also a plus.

Ciaos,
Kristof
I have it installed now and it worx good. Only problem is that it keeps muted VERY long (about 10 - 12 secs) when the BA produces a sound. Have to find somthing to fix this. I know this is a problem of the carkit because when the mute wire is grounded it switches directly on & off.
Just purchased this, and it looks pretty good, but the instructions are a bit naff.
Do i gather that the car kit's control box in effect gets placed in circuit "between" the car's head unit and the Front Right (or left) speaker. The cables are labelled radio FR + and - and FR speaker + and -. Do I just cut the iso cables for the front right speaker and connect the two ends to the ends of the car kit cables? I'm fine with car audio so this shouldn't be a problem
Does the car kit mute the radio for *every* noise or just phone, tom-tom etc? I guess I could just stick a switch in the middle of the mute circuit if i wanted to stop this (like WMA playing through aux in on head unit)
Hoping to have a play tonight...
It depends on the car you have. I have an Opel Omega with Bose Sound System fully integrated. At the passenger side under the glove compartemant was a plug that had al connections. The BSS has a phone audio input that outputs the pda sound to all speakers including Tomtom, and yes, all system sounds come over the speakers too. If this bothers you you could turn the sounds off in the Sound & Notifications menu. Check your car, maybe it has such a same plug (for factory fitted Carkits). First i wired it directly to the radio but it produced a horrible sound when the phone was cradled. It sounded like if 10 cats where fighting on the backseat. But that is over now. Could you let me know how long it takes for the mute signal to UNmute it after a sound is played. It takes about 12 secs here and that is WAY to long for every damn sound.
GaMeR64
Oh ok. I have a vauxhall vectra with the same mobile pre-wiring so I wonder if that might work for me as well.
Did the car kit cables just clicp straight in or did you 'butcher' them?
I'll let you know about the delay to turn mute back off again once i've fitted it (probably at the weekend )
What i did not to kill the originall plug is that i soldered off a connector from a broken VGA card. It should be the same one as that where you plug in your IDE HDD at the back off the HDD (male plug strip). I soldered all the carkit wires to that. It almost looks factory fitted. Pay special attention when connecting the audio wires to your plug. At first i fixed tham at the back of my radio but that made a sound of 10 fighting horny cats on the backseat. Be sure to connect it to the plug because there is some filter between it. At least that`s with my carstereo (Philips CCR800 /w Bose Sound System.
If anyone could help me with modifying teh Tomtom 5 sounds the help will be appreciated. I unpacked all the voice files but i can`t seem to find the RIGHT editor to open these .ogg files. I tried SoundForge and Audicity but no luck. They can`t open them.
Hi,
My Vario II justification to the misses was that we'd be able to listen to music in the car with it (our CD player is dead).
Has anyone come across an FM transmitter that you can power from the car cigar lighter and plug directly into the mini usb socket on the TyTN?
Cheers,
Steve.
I'm looking for the same thing
I bought a SONY MEX5000 BT stereo that uses Bluetooth streaming. It is so cool! much better quality(sound) then the radio ones. I dont carry CDs anymore just everything over BT with MP3s.

and how to connect ?
--> no way @ this moment ...
Try Nokia HS-12W. Google to see how it looks like.
It is a bluetooth Stereo Headset which you can listen to MP3 played from Tytn.
It is also a standalone FM Radio by itself without the Tytn at all.
I have one, cool.
Hi and is there a bluetooth receiver taht one can plug into a stereo ?
HS-12W is a Wireless (no wire between it and phone) Stereo Headphone via Bluetooth with Build in FM Radio.
What I meant about the bluetooth reciever is if there is one that tha pda streams music and is recieved by a device that can be plugged into the home stereo, same principle as a headset only differance is that it'll go to speakers.....hop I made it clearer this time... or maybe it's that I am not gettin it jaja
You are refering to Home Stereo Hi-Fi Amplifier/Receiver to speakers. Well it is something I was thinking about some years ago when I first read the white paper on Bluetooth v2.0 A2DP Profile.
But Hi-Fi industry in term of following latest trend is normally a little slower than the computer & mobile industry. So far, not that I know of that there is a build in Bluetooth Hi-Fi system including speakers. Maybe it is time to do a google on this topic, it would be good if there is such solution to get rid of the messy wire connections.
I do know that there is such thing as Bluetooth Donger, which is a bluetooth device with a headphone jack and you can plug the headphone jack into the Hi-Fi headphone jack and bingo you have wireless music with you wireless headphone, but bluetooth is quite subject to surrounding interfence, so you may have broken music in your ears.
The is also some not so good old technology using Infra-Red. The better ones are the wireless headphone sets using RF frequency which you can listen to music even you and your hi-fi are in different room.
Hope I got your question right this time.
Hey CWKJ,
Thanx for your reply. Look at the following link:
http://www.expansys.com/product.asp?code=130588
It's a bluetooth speaker, but what I am looking for is something that can make any car home stereo into a bluetooth reciever...
You mean something like the Tunestage II for the iPOD?
http://www.techdigest.tv/2006/10/belkins_tunesta.html
I'm looking for something similar that will plug into a car stereo - i.e. a bluetooth receiver which will plug into the external input of my car stereo, so I can stream to it from my TyTN - anyone know of anything?
PS Yes, I have seen the Parrot MK6000, but I don't think its out until Q1 2007....
BINGO!! Yes like this, only that you don't need the transmitter (tytyn would be it!).
check out the I-Tech S35 clip. A2DP receiver with a 5mm headset jack. You can cable this to your car with an adaptor cable. The I-Tech doesn't skip either!
Yes! this seems to work! jajaj do you actually use it? or know of someone that has used it with this purpose?
Once again thank you for your responses!
I've not used it myself for this purpose. I've no doubt that it will work though. What I am interested in is the usable range. The applicaton I have in mind will require 4-5 meter range from the I-Tech device to my TyTN.
C.R
Ok, you are talking about car hi-fi system, the speaker looks good.
For Home hi-fi system, maybe there isn't bluetooth audiophile speaker yet.
For the car hi-fi system, there are some with the audio output (the Left - Right or White - Red cable build-in type audio output cable). Buy another cable adaptor (Left - Right/White - Red to stereo headphone cable) and the Bluetooth Donger, connect them up and you will have the audio on you bluetooth speaker. Hope this works!

Does anyone know if the HTC P3350 W100 Wired Remote Control
http://www.expansys.com/htc/p_htc_item.aspx?i=147564[/URL]
will work with the Cingular 8525 (Hermes, TyTN)? This is sold in Europe and can be had in the US from Mobile Planet which seems to be the same as expansys.com.
On the European HTC site there is also a media fix that may apply to this accessory as well as the Y connector.

Downloading and installing this driver update will provide your HTC mobile device with the latest available optimised software for use with the following accessories:

The hot music setup for Mogul and 8525
I just purchased the HTC RC W100 Remote from Mobile Planet. It connects to the phone's extUSB and provides a 3.5mm headset jack that carries the mic port out to the connector. It has a 36" cord so there is a lot of cord if you have a long headset cord.
The head has controls for fast forward, pause, +/- volume and you can answer/end calls, mute and put a call on/off hold. This assumes that you have a mic on your headset to talk into.
The http://www.Europe.HTC.Com site says it is for the TyTn II but it seems to work with both the 8525 and the Mogul . . . It is not on the USA site at all.
I use the Sure SE110s stereo headset (individual internal sub-woofer component) and added their MPA-C cable that has a mic in it (Thsi would work for any headset). I have not found any other solutions that wok this well.
The standard headset really has poor quality and is uncomfortable for my ears. Bluetooth is either a mono headset w/ mic or a stereo headset (no mic) and the battery life is unpredictable.
This way I can ride my bike and control my music while the Mogul stays in my camel-back and when a call comes I can actually answer it and then go back to listening.
Very cool setup.
So this doesn't solve the headphone problem? Can't I just buy this and a pair of headphones? I don't need handfree anyway
E: Why a 36'' cord? I totally lost interest

I do not know what headset problem you are referring to but this is definitely a solution if you want to listen to music with a good stereo headset. I just happen to like the Shure stuff because they eliminate some road and wind noise while I am riding my bike or skiing. Also the higher end ones actually have miniature tweeters and sub-woofers built in.
All you need is the W100 and any headset with a 3.5mm jack.
As it turns out, I just found out the unit has a built-in mic and that eliminates the need for a more expensive headset that has a mic. There was nothing in the manual that came with it that talked about the mic! So RTFB does not work!
It also comes with a small disc that has the driver in it. I tried to install it on my Mogul but it said that I had the latest driver . . .
As far as the 36" cord, my Shure headset comes in 2 pieces, the earphones are on a short cord so it is not too long. If you had a standard headset, it might get a little long.
The other side of the Shure headset has the connectors that go into the device(s). This way you can have several different connectors for different phones, MP3 players, etc. Blackberry's and Razor's have different jacks and most cell phones like the HTC 8125 (Cingular) use a 2.5 mm jack.

Hi All,
I have just purchased and tested this product. It cost just £22 from Ebay. Quite a bargain really. The build quality is quite poor. However, the D2 does fit quite nicely and you don't need to fiddle with it too much to get the mini USB connected. One strange thing is the side flanges. They do overlap the green and red phone buttons slightly, so you could find yourself accidentally calling someone when inserting the D2 into the cradle.
Once in, it is an excellent product. The sound quality through the car radio is superb. Even driving through London (where the airways are filled with legal and illegal radio stations) there is no interference with this transmitter. I have tried a few of these type of FM transmitters and can happily say this is easily the best so far. The volume on the D2 needs to be turned down to about 13 or 20% on the HTC, otherwise you will get some distortion when playing loud music.
Re-tuning is a breeze with the back-lit LCD screen, if the frequency you have it on has some interference.
One problem is making or receiving a call. When a call comes in, you can hear the ringing through the car speakers. However, this device disables the D2 microphone and does not have one built in itself. The only work around for this is to have a bluetooth headset. Therefore, once a call comes in, the bluetooth headset will then provide the sound and microphone and so you can speak/hear as normal. The car speakers will be disabled once you accept the call through the bluetooth headset. Obviously the headset will need to be connected first. Personally, I use a small programme called bluepower. This turns on bluetooth on my D2 when it is being charged and then turns it off (to save battery) when it is not being charged. Therefore, as soon as I put the D2 into the cradle, it links with my already paired bluetooth headset
So, I can now sit in my car with my D2 charging, playing music through my car radio and make/receive calls using my bluetooth headset without any problems....
All sounds great doesn't it?
However, there is one small problem.
If I choose to listen to a different radio station, I will not be able to hear my D2 ring or hear when an email/text comes in, or to the voice guidance on my iGO8 (not that I use it).... You may consider this a safety feature because you don't want to have this distraction whilst driving do you? Obviously you can still see these events in the usual way, if your screen is turned on. This is not such a huge problem I don't think, but some might.
Perhaps it will be easy to be able to somehow link up a working microphone with this system and have a rather decent hands free system, but I don't know how to. I have seen other threads which have also described this problem with other such systems, but never a solution except the bluetooth headset one. Maybe someone can suggest a registry tweak for this or a Mortscript programme???
Anyway, to conclude, I am very happy with this purchase, especially at the price.
Hope this helps someone
will the Pure fit in a TD2 cradle?
Will the Pure fit in a TD2 cradle? The bottom ends appear to be differently shaped. Is it close enough that the two can be interchanged for a cradle like mitsi posted?
I want a nice cradle with a built in usb plug so I dont have to figit. The proclip one is too darn expensive. Whereas the custom fitted car cradles for the TD2 are plentiful...
Mic For the FM Transmitter ALMOST !!!
Well like you i bought one of these fine products I did come across a couple of issues (and work arounds).
1. At certain output frequency's the GPS did not work ??, noticed that when the power to the FM Tx was removed the GPS signal returned. as I tried different channels the interference varied so worth looking out for.
2. Again at different output channels I would pickup the mobile trying to make a connection to the network (approx every 10min), again changed the channel the effect varied from bad to zero.
Microphone, I took my unit apart and the pcb has the position for a MIC marked on the pcb but no mic fitted. I took out a mic from the supplied handsfree kit supplied with the phone this fitted and off I went to try but no luck.
On further investigation the mic needed to be wired pack to the usb plug BUT the pins for the plug are enclosed in the glue used to hold the plug in position and there were no leads off the plug to wire too !!!!!!!!!!!!
But like u the unit is still worth the cash
