In my quest for the best combination of features, in light of interchangeable PX5 SOMs, I may want to transfer the BT module that works best to the HU with the best screen. I'm not worried about the soldering and of course the BT selection needs to adjust in the factory settings. Is there a known reason why this would or wouldn't work?
Which by module is "best".

I'm sure that's a controversial question. When I first got an Oreo HU it had a BC6 BT module, and my boss said it sounded very good. Presently I'm running an Oreo SOM in a KSP HU, with an SD-968 module. At least I think it's an SD-968; I lost the MCU configuration, but it functions when set to SD-968 and I recall that's what it was. Maybe I'll know for certain the next time I open the HU. Anyhow this HU got a poorer critique when used on a call. It's all very uncertain since there are so many other factors, the MCU, the amplitude of the MIC input, the HU circuitry, the quality of the phone's connection, and maybe the ROM has an effect also. Perhaps I'll get around to doing a careful study.
Update:
The HU with "good" BT has a short red wire antenna connected to the BT card, which is vertical. This gives me something to try on the HU with "bad" BT. The symptom is, while making a call, the sound fades out a lot, it is not a steady consistent connection. I don't think it's the phone's connection doing this.

Interesting write up. I would have thought that the md725 be a contender, because it is the integrated BT/wifi chip, which is connected directly to the SOM via USB. Seems the developers have a very poor BT implementation.
Agree multiple factors from mic to module.
Recently I bought comfast CF-WU725B USB card, to see if It can be used instead of integrated BT/WIFI unit.
Mine MCU has md725, so as a BT HF unit it's useless!
Lot of "hishes", echoes, and sound quality like, when you will be almost to far from receiver.
But the problem is that when I plug this card to USB port in some time unit will freeze, and only reboot helps.
I can tell that drivers are get loaded, cause card LED start's to glow.
But when I disable BT from Factory Settings I get no BT, no WIFI and when I connect this card to USB its drivers aren't loaded (no LED light on card).
Is there anyone here that tested this card with success?

I only found a type 1 by buying a GS xtrons board, desoldering and transplanting into my JY board, replacing the type 2.
suspect it's a matter of factory configuration of type 1 and 2 by the OEM but haven't been able to validate yet.

So did you find someone that would sell you one of these modules in the end? I'd still like to get hold of one as I had the um02wbs-8723bu-v1.2 which I removed and replaced with a USB MD-725 Type 2 (this was before Oreo was out).

I'm looking for a Bluetooth remote to use in my car, to control my G1 when it's hooked up as a music player. This is both a safety and convenience concern.
The starting point is finding a remote control that transmits Bluetooth directly to the G1 (i.e., not infrared or wired). It needs, at a minimum, a forward and a stop button. Reverse, pause, and other functions are nice, but not mandatory.
The other half of the solution is software to control the media program in Android, which may or may not already exist; if not, I'll commission someone to write it. Maybe I can even offer a turnkey system for sale if there's enough interest.
I know someone's will say "search the forums", and I did. What I found seemed to be focus on wired remotes for another HTC phone, or remote controlling your PC with your phone. But if I missed a relevant post, please do correct me.
Ideas are greatly appreciated.
remote
there is a remote for gaming used for the n95 i saw on a website it worked for android on a basic level. maybe that might help. in the development of this
Found this on another thread http://www.youtube.com/watch?v=87Wc0KqnW2M that some people are using. Jabra BT3030
Aux cable from car stereo plugged into remote. Remote paired with phone. Not *completely wireless* but atleast you don't have to look at your phone.
Does that get you anywhere?

Hmm, I posted a reply to this, but it isn't showing up. Maybe forgot to submit.
Anyway, thanks for pointing this out. I had seen this a long time ago and forgot all about it. That's exactly the kind of thing I want. Here's the instruction manual, for anyone else who might be interested. It's about US$55.
The only problem I see here is that it'll register as a headset and thereby disable the sound coming out of the extUSB connector in the car.

It's the Zeemote JS1, and this blog has a video showing it interacting with a G1. This may ultimately be what I'd have to go with... it seems to be designed solely as a controller, without A2DP getting in the way. But looks like it needs some kind of interfacing software, at least on the Nokia. At US$20, I should just get one and play around with it. Cheaper than buying another car stereo with BT built in.
Dual Infrared + Bluetooth Remotes
FWIW, I ran across two rare, interesting items.
One is the RicaVision Vave 100 Universal Remote. Unfortunately, it's $349... but in theory, it would control both your car stereo (via infrared, which the majority of remotes use) and the G1 (via Bluetooth). It's able to "learn" commands from 24 infrared devices, and has a 2.4" 240x320 color LCD screen. No PC or internet connection is needed for configuration.
The screenshots show artist/track info being received from Windows, so it's Media PC-oriented, but still a possibility -- assuming you could program it accordingly. If so, just carry it back and forth between home and car: use it inside for your TV and PC, outside for the car stereo and G1.
The other device is the Ricavision SideShow Remote for the same price, also having IR + BT transmitters. This is purpose-built for Windows SideShow, and has fewer buttons -- volume, play/pause, prev/next, etc. It's smaller than the Vave, but still has a 2.5" QVGA screen. This is perfect for my car setup, but there doesn't seem to be a learning mode or any way to program, so the chances of it working are about zero. Boo!

If that worked in my case it'd be perfect, and it's the smallest form factor yet. The only problem I foresee with this and the Jabra is that they'll want to subvert my wired headphone output over to A2DP. But for $13 I'll probably take a chance.

Well, I finally bought a Jabra from there. I'll play with it and report back on whether it'll work like I wanted above.
Meanwhile, I didn't realize until looking more closely that most of them were fake. I've been burned by counterfeits before, and sure enough, there are a ton of them on fleaBay. I made this graphic to demonstrate:
Aside from the logos, they look identical. Price is an obvious warning, but not always. Location is another: I'm wary of shipping from Hong Kong. OTOH, just because it says Jabra doesn't mean it's real... the Motorola H700 is another example where it's nearly impossible to tell them apart online.
Unfortunately, even with VeRO and the rules against keyword spamming, this junk can be found all over eBay.

In theory, if it's able to connect to one phone's A2DP, it should connect to any. But I wonder if it has something to do with the ROM you're running?
I've noticed the G1 needs some finesse when connecting and pairing BT. Also, there are different steps you can take that all arrive at the same result (ergo, lots of trial and error).
Anyway. Now that I have the Jabra, my next problem is keeping A2DP, HSP and AVRCP separate... more on that soon.

Here is whats interesting; I have tried the BT3030 with several ROMS and I get the same results (I even tried it on stock and then rooted). When paired placing and receiving calls work fine. The problem arises when you try to listen to music, the sound skips constantly and I haven't figured a way to fix this permanently. Do you experience this problem (skipping sound)?

I got 3 knockoff bt3030s back in october (from dinodirect... shady) at $15/ea it was an ok price...
I too have the skipping problems on my Droid, but I just discovered how to fix them. Go into bluetooth settings, long-press the jabra bt3030 device, select options, and deselect phone audio and reconnect the device. Now, no more skips.
I don't know if it's the bt3030's fault, I think it might be an android bug where audio gets routed over phone audio instead of a2dp. This is evidenced by the skipping audio--headset audio only has something like 8khz of bandwidth.
It kind of sucks that phone audio has to be disabled, but in all seriousness, I use the bt3030 for a2dp far more than phone calls, if I need to make a phone call over the bt3030, I'll reconnect the phone audio and disconnect it when I'm done.
Don't know if anyone still cares, but for the record, and for searchers, there are these options:

Hello,
I have a major problem with my lower microphone (on the USB flex board), the microphone does not register much sound at all (very faint sounds are possible if you scream as loud as possible into the microphone directly).
I have replaced the USB flex board (properly, everything is connected correctly and the USB port works perfectly), but the microphone is exactly the same...
Anyone have any ideas? It seems a couple of people have similar issues, has anyone found a fix yet?
Also, does anyone perhaps have any ideas about how to force the top microphone (speaker phone mic) to engage as the active microphone during regular voice calls? I am 100% sick of using speaker phone for every voice call, especially considering I need to make private/confidential calls for work :\
and yes, I have removed the rubber housing as well and tested it without it, it makes zero difference.
Youve tried to repair it on rhe cheap and failed.Maybe take it to a repair shop and get it done properly.
And from your other thread,the spare one I have here has part no gt-i9100 rev2.2(so maybe the one you bought is still faulty )
Sent from my GT-I9100
So you've followed me to my thread because I made a post you didn't like in another thread, and offered complete shinfo.
Please, do not post again.
I am a fourth year EE student, I know how to replace a minor circuit board correctly.
Anyone who has any real advice, specifically about whether or not this may be some form of software issue, and with regards to my question about using the other microphone in voice calls, please let me know.
My mistake-I thought I was replying to a poster named Bodurr as he made a couple of threads about mic problems aswell.
He replaced the board and its still not working.
And I see what you mean about the other thread-I can assure you I never twigged it was you.
Anyway,if you require help,its advised to state what rom etc your running.That way someone could say "if your rooted make a nandroid backup then flash stock rom and see if problem persist".

Have made a nandroid backup and reflashed to stock a couple of times (including stock kernel and then CF root kernel) and nothing makes any difference.
The issue started whilst on gingerbread and has now carried on to ICS...
I'm seriously completely stumped and have no idea what is causing it :\
I've had a quick look and its advised to test using voice recorder to eliminate a hardware issue.
Other thing mentioned was to change audio values(but maybe need to be on GB to access and change values in the *#197328640# menu.
I don't know if you've done this already.

Just tested again with voice recorder (first time I have done this since swapping the USB flex board) and it's exactly the same issue.
There is SOME sound, but you need to have the volume on full with your ear right against the speaker to hear it, and it's still very faint like that.
What a bizarre issue, it seems no-one knows how to fix it either :\

Yeah, got the solution. It's actually the board/flex cable itself. Took me three boards to find that out. There is a lot of b-ware boards on eBay that were actually thrown out by Samsung because they did not pass QC. Just get a genuine spare part and your mic will be fine.

Why wouldn't it be compatible. A higher revision number usually suggests that something has been improved. BTW I initially had a 2.2 sub circuit board, now it's 2.3.
Well the new board should look like the old one. I think I took a picture the day I switched my board out. I'll try too find it later.

I purchased an Enco B046 Android-powered head unit for my car, and there are some things I'd love to be able to fix, if I could somehow acquire root access. Most importantly, the GPS functionality. Here's what I know about it:
1. It's a Telechips TCC8925
2. It only has one USB port (Female-A), and it appears to be Host-only. Hooking up a Male-A to Male-A cable between it and a PC, the PC doesn't detect anything on the other end. Hooking up an OTG cable between it and another Android device, the Enco B046 tries to mount the other Android as mass storage..
3. It's running ICS (4.0.4)
4. There's no pinout on the board for another USB port, nor any other pins that are giving +5vdc
5. It does have an SD slot and a card in it. It mounts and works fine.
It's relatively similar in size and form to this:
http://www.slatedroid.com/topic/36988-cx-01-cortex-a5/
Since I can't connect to it via USB and control it with ADB, that eliminates all of the ways to root the device that I have come across.
The most important thing that I need to do is to update the framework.jar, as it suffers from an incorrect GetSpeed function that throws off pretty much every GPS application. It's calculating my land speed at 1.852% of the actual speed. I have fixed the error, and repackaged the framework.jar, but to updated it, alas, I need root access.
It's a shot in the dark, but without some sort of physical connectivity, I'm at a loss. Does anyone have any ideas how I might acquire root on this thing, via software only? Or other ideas as to how I might be able to connect to it?
Thanks!
After further examination, the board has one button on it. If I hold it down during bootup, it goes to a black screen, but a red LED light stays on solid on the board. Generally, that light flashes. I'm wondering if that button doesn't enable FWDN, or Fastboot mode. Maybe that's the ticket.
Hi my friend! Any news?

No news yet. I do think I've figured out how to get into FWDN mode, so I should be able to take a complete backup of the NAND, etc. That doesn't do me a whole lot of good, though, since I don't think you can inject something into an FWDN image.
I suppose I could try to recompile it completely from source, but I'm not sure what all drivers are compiled into the current system, and have no experience doing anything of that nature with Android before.
I wish there were a magic "root" apk I could install, and be done with it!

As usual if we push hard enough and make enough noise on the forums we'll get there, if Charles has to refund every paypal customer because the GPS is crap....he'll find a way to get us root, it's as simple as that
Found this, I don't know if it can help but perhaps the guys who are playing with it can help you....
http://www.cnx-software.com/tag/telechips/
I think the button on the board may actually put it into FWDN mode, but the USB port configuration doesn't seem to allow the board to act in Device-Mode in any way. If you power it on while holding down the button, it seems to do something. The screen shows "NO SIGNAL" which is what would happen if it goes into FWDN mode. But, I can't get anything to communicate with it. It doesn't show up in device manager at all, on multiple PCs.
Looks like for now, our only hope is for someone to create an APK that somehow magically roots the thing. I'll go ahead and hold my breath.

I am also searching for an answer to this one as i have the same issue.
Got it! follow this link and use the package and instructions provided

Sure did just rooted my car stereo... had to update the Superuser app and a few others...... next task is to figure out what tweaks to build.prop i need to get all apps in play store.... especially the google apps.
FYI - after applying the update the screen flickered on the boot up. I reset the device (power cycled via the reset button) and then powered it back on and all is good!
I may be able to post some screen shots in a little bit if you like.....
Car stereo..... as in Enco B046 ?

WHOA!!! That bad boy is $800 now I only payed $378 shipped
For which car was it ? Because 800 is a bit expensive, we're at 450-500 for a BMW unit, look at www.szenco.com
Thanks a lot for the link anyway, I'll try that tonight....

Well, because of you it can be rooted now so the price went up the ceiling
I bought it to use in a 2005 Ford F-150
If you can pay for the gas you can pay 800 for the stereo

This is awesome, thank you very much! Going to try it tonight.
Any luck with build.prop?
Have you guys experienced of the following problems(before rooting)?
-SD Card error message(not related to external microsd)
-Some apps installs but then give a "no sd card present" error
-Google Nav: works for a short while then all you get is "searching for GPS"
Im running the Malaysk ROM for RK3188 on my Eonon GA5153F
Since flashing the Malaysk ROM my bluetooth settings keep reverting to default, carkit device name etc.
Even if I manage to change them and even hold the settings for a coupe of boots on rare occasions they always revert to carkit and the default pin.
This problem has repeated over 2 versions of the ROM and posting in the Malaysk RK3188 thread brought nothing useful in the way of info.
Anyone have any ideas or suggestions how to sort this out, its very annoying and I desperately need bluetooth handsfree back for work purposes.
Dont know if its relevant - I also have the GA5153F and although everything was fine with Malaysks 4.4. ROM - when i updated to his 5.1 version - bluetooth did not work until I changed the bluetooth adapter in Factory Settings to the non "b" version (same model number) since then it works great.
Yep, youll get nothing with the wrong adapter set.
Unfortunately this is a different fault.
Anybody?
I know others have suffered this problem, doesnt anyone have any other suggestions?

Im sure it is, but it doesnt help solve the real fault with the kit Ive already purchased, fitted, and seriously need to function as I regularly need to take calls when driving, Im a courier.
Frankly I didnt have any call quality issues when it was working, its the total lack of function thats a bit of an issue!
Is this a hardware fault? Is it a Rom fault? IS it a media board fault? IS it as simple as a file somewhere being over written or with bad permissions?
Non b worked for me but now I have no wifi

It is essentially a manufacturer (software) issue. Malaysk has mentioned somewhere that Chinese developers messed up the BT stack. You must understand that these units use a plethora of BT boards from various suppliers AND in various HW revisions. Nobody will work on a universal BT service that accommodates all these boards. Your best bet, if you want to use the on-board BT, is to find a ROM that works, through trial and error, and stay with that one.

Thanks I am aware of the hardware diversity. It is frustrating that these companies have a weak attitude to stability. However the original rom had functional Bluetooth, and the Malaysk rom is supposed to be based upon it, thats what is also frustrating.
I tried posting in the Malaysk thread but it was largely ignored, scoffed at and lost in all the noise.
Anyone else?
Hi there,
At 4pda, they are writing, that some PX5 units have troubles with WiFi/USB below 0°C.
It looks like my Witson unit (MX2 MCU, PX5, Android 8) suffers from exactly this problem. The last days we had warm temperature and USB and WiFi worked perfectly.
Now I went outside and the issues are back. It's 0°C now here!
Can anyone confirm this issue?
At 4PDA, they suggest a fix by adding a screw-whole + screw to better fix the proccessor unit:
https://4pda.ru/forum/index.php?s=&showtopic=883219&view=findpost&p=77467642
It looks like the processor unit is only fixed by 2 and not 3 screws and especially the two most outside pins, which are responsible for wifi and usb suffer from loosing contact with cold temperature.
I'm keen on trying to hardware fix. But I'd like to know if someone has experience with this?
Christian
Seems like a easy issue to check for and then apply if your unit has this issue. You might help others by testing the solution and posting result/images.

I now read the whole post in an ugly into german translated version.
The theory with the processor unit is not confirmed, the people over there discuss about powering issues for the usb ports, temperature-related problems etc. No finally confirmed fix seems availbale yet.
As my unit is less than two weeks old, I am claiming warranty. At least I purchased trough an UK dealer with paypal, so first I hope for a replacement.
If I don't make progress with that, I'll open the unit and look for the issue.
If someone elso would have a confirmed working fix, I'd try it.

There's another thread where a few of us have been researching this problem. The fix is posted HERE. There's no need to open the unit.
There's links in that thread to the 4pda forums where they explain what the issue is also. Long story short, it ends up being a manufacturing defect relating to the USB host controller. Newer versions of the board don't have this problem. But I can confirm the above fix does work like a charm, I've tested it several times.

Hi there, will comment in the thread you linked. I have running that fix with tasker already but still have partial drops of the host controller. I'm also working on a tasker task to switch WiFi on as soon as it gets off.

If anyone is still interested in a hardware fix, my KSP units have a 5-pin IC for USB current limiting and I found if the part is cooled, the USB will not turn on when it wakes up. I replaced one with a TPS2001DDBVT, same package and pinout but better specs. It passed the bench test. I haven't gotten around to installing the HU yet.
Update: I installed the unit with replaced ic, and it behaved differently, though not yet correctly.
It's worth noting, a Dasaita HU which has not exhibited the low-temperature wifi issue has the same USB hub chip, but a different (much larger) crystal attached.
I installed the newer usb hub chip as mentioned in the other thread. No more low temperature problems, however if I reboot the unit via software (with a rooted app), the wifi does not come on. One must reboot with the reset hole. Do not try this while driving.

Hello
Can you make a photo of crystal and send it here?
Dasaita change something in board design (usb hub for sure) and currently doesn't exhibit cold temp bug.

Hi
I have the same problem on my Dasaita bought on september 2018!
which upgrade do you suggest? hardware or software?
the problem occurs only with the dab module connected to the cable with 2 usb, while the single USB cable, which I connected the 4G wi-fi router, always works.
If I will installed the hal9k ROM, could I fix the problem?
thanks

I'm going for HW repair. I've ordered GL852 sop28 from ALiexp (0,55+3,4USD shipping).
Dasaita knows about problem with GL850, but they proposed to replace chip by myself or to send them SOM board and wait till they resend it back. well, i'm definitelly not happy with their response.
I hope that replacing USB hub will solve at least one other problem - random unmounting usb drives and problems with copying files from usb to sd-card.

You need to open-up your HU to check. Also there is a thread on xda regardig WiFi/BT issues;

Ok. I'm going to check the chip model.
I haven't problems with the Wi-Fi or BT.
when the temperature is low the DAB module connected to the double USB cable doesn't work, everything else are fine.
could I have your same problem?
I changed the gl850 ssop28 with the better version gl852g. Now I have no real problems anymore with my xrc unit. There is a software fix in hal9k 3.1.1 in the mod settings but it was only working when it was not to cold. I had in cold days allway to wait and reboot the system ...

No, it's not really easy, but without no skills before I did it. I just watch some desoldering and soldering videos and tried a bit with an littel another broken board with a ssop8 socket on it. I desoldered a lot and soldered a lot on it and then I change the chip on my mainboard.

I used a soldering iron beacuse I din't had a hot air station.
