I looked for the search function but couldn't find it, so don't slay me. I have the official vehicle dock and lighter plug charger that comes with the dock hooked up. When using the plug to charge and listening to music from my aux port on radio there is a lot of engine noise during audio playback. Is there something I could do to suppress this noise?
I have used something similar to this:
Kensington Noise Reducing Car Audio AUX Cable
The one I have used is from Radio Shack, and works very well.
Thanks! I'll give it a try.

I bought one of these off of eBay http://cgi.ebay.co.uk/In-Car-FM-Tra...s_RL?hash=item3ef725a26f&_trksid=p3286.c0.m14
Unfortunately its very disappointing. It does not charge the phone whilst plugged in. The audio quality is acceptable whilst the car isn't moving. Part of this is due to the very poor quality USB charger supplied, a better one from my Sat Nav improved the situation slightly.
I already have a cheap transmitter that plugs in the 3.5mm socket, but this seems to cut off the bass from the music.
I am looking to replace my Sat Nav and MP3 player with the phone. I have already ordered a car cradle, but would consider a cradle with built-in FM transmitter. I also don't really want the hands free built-in like the transmitter above. I would rather use my bluetooth headset.
Any suggestions?
I know people have mentioned the motorola T505, but I suspect that the battery life on that isn't more than a couple of hours.
Hi well as far as iam aware no of these will charge any of the HTC devices ment for audio only but could be wrong

I got a slightly different one, but the link now shows this item... Universal audio input, usb socket for charging anything you choose. Audio quality is reasonable, but it's a transmitter so it will always sound a bit dodgy. Also, the hero is a phone so its audio quality isn't incredible either, but it'll do for whiling away a road trip!
The only way you'll get high quality sound is with an aux input cable, decent speakers, and a high quality source file playing on a decent mp3 player.
Product-specific docks are stupid.
Use this with the device you bought of ebay...

Plug the fm transmitter into the audio part and the charger into the charging part.
Then just plug this into the phone with those parts already connected
I've got a USB charging cradle in my car which works fine.
I use a 3.5mm cable to connect my mp3 player to the car stereo which works fine.
I tried playing music from my HD to the stereo whilst charging and I get awful white noise and a constant pinging noise. If I take the phone off the charger it works fine. I can't find anything in the wiki or forums and I've seen some people on other forums with the same problem.
Anyone know what is wrong with this setup or I need a different spec cable (I guess its a standard stereo 3.5mm cable, so 3 contacts and I think the HTC one has 4 coz of the mic, but it works fine when I stop charging it. I guess it could also be a problem with the pins on the USB charger, but I thought the HD didn't have the extUSB connection.
I'm off to the USA on Sunday with a hire car so it would be really handy to be able to charge and play music!
I purchased the official Atrix car dock about a month ago before going on vacation. The dock has worked great and was indispensable for using the navigation in our rental car.
But the audio connection on the USB power cable has never worked for providing any audio from the device. My Bluetooth was disabled, but no audio (of any kind - music, calls, etc) has ever come out of the line out/headphone connection on the car dock cable. The only way I can get audio to the car is by connecting the cable to the headphone jack on the phone itself.
I've done a lot of searches for people who have had this issue, and the one or two instances I found have not provided me a solution.
I recently remembered that the multimedia dock I purchased also has a headphone jack on it, so I tried to see if this output works the way it's supposed to. I started playing music through the internal speaker, then connected some headphones to the output jack on the dock. The music immediately stopped coming out of the internal speaker and was audible on the headphones. Disconnecting the headphones sent the audio back to the internal speaker.
So it seems that the USB audio on the phone works and can re-direct audio to the dock audio jack when it's available. But the car dock audio jack still does not function. Do I have a bad car dock? Should I send it back, or is there something else I should try?
Sounds to me, like either your dock or cable coming out of dock is no good. My car dock throws audio out of connection on usb plug with no issue.

I returned the old cradle and cable to Motorola. The new replacement has arrived, and the audio is working perfectly. Thanks for the help.
Do either the HD Station or the Car Dock have an NON-amplified audio line out?
Music sounds pretty crappy playing it through the amplified headphone port or bluetooth audio to my truck. Looking to used one of the docks instead if they have a line out.
The official Motorola car dock has no line out. Only a micro usb charging port in.

Are you talking about the Car Dock? If so, that rules out that option for me.
The HD Station looks like it has a 3.5mm audio port, but i'm not sure if that is a line out or amplified?
The car dock has a 3.5mm female connector at the lighter adapter. I have that running to the front of my truck's deck.
Check the manual here to see if that's what you're looking for.
I have the car dock and have tested the aux out. Its ok but the sound quality is not that good. It like im listing to xm in my car.. sound is ok but not the best. Im am comparing the quality to my Ipod that is hooked up to a digital out to aux cable that sound great. The day someone makes and android player that sounds as good as my ipod is the day i can fully leave apple behind.
this might not directly answer your question but, I have used BT in a few cars and with BT headphones. It sounds fine and I've never had any problems with sound quality. as an AUX input it sounds ok but, playing music off my phone gets pretty old fast. I personally prefer to use USB flash drives. I just put a stereo in with usb and an aux for 90 bucks. i can add on BT for 50 but, i have no use for it really. decks with bt built in cost about 160+. anyway, if u have a usb port, u can use ur phone as an flash drive and play the files directly off of there.
as far as docks go, i just use a cup holder or the dash space that i have.

Wow good catch. Hadn't noticed that. I can't make use of it because I have no aux in, currently using bluetooth, but good to know for future cars.
Thanks!
Has anyone noticed terrible noise when using an S3 docking system or cable to output both Audio and Charging?
- extreme hiss and random noise, machine processor noise, crackle etc. (only if charger is plugged in as well)
- after 2 seconds of no sound, you can hear what resembles to be an AUDIO gate...that kicks in and mutes the noise until you trigger your next button sound.
- Even if you listen to a song, and think it doesn't happen while listening to a song...IT'S still there...fighting the song and causing degradation in Audio quality.
- not too mention, phone calls will NOT route through the USB jack, and music and navigation type stuff.
- if you unplug the charger, the sound cleans right up and sounds fine. It's the combination of having the audio and charging outputs all in one.
- ground loop isolators do not help
I have a background as an audio technician and some electronics skills and I did hours of testing and modding...unfortunately! All failed. I own an Ibolt car cradle (which I did most of my testing with), a KiDiGi desktop docking cradle, and I even hand made a cable that could trigger docking mode. All three of these scenarios FAILED with the NOISE factor.
I have resigned to thinking it is a hardware design bug with the S3. I have modified my Ibolt so that it sends out audio from an extra cable that plugs into the Headphone Jack...which as a bonus, as sends Dialer audio.
(I just realized that this is the i9300 thread, and I have a i747m but maybe this thread could help all the same)
I've had three S3's and used USB audio out to my car stereo via 3.5mm. None ever generated any additional noise.

Eddie...can you confirm these points:
1) You have a usb cable or dock that comes out the bottom of your S3, and it splits into USB for charging....and 3.5mm for audio? (NOT THE HEADPHONE OUT)
Is it a cable or dock and would you mind tell me the name of it?
2) What do you plug the audio into?
- stock car audio input
- front aux input on a car deck stereo system (stock/aftermarket)
- rear aux inputs to aftermarket stereo
- other?
3) with the steareo turned up fairly loud, but no music playing, do you hear any noise when you click buttons (assuming you have audio enabled for button clicks in Android settings) When pausing between loud music, do you hear any white noise, machine noise, hiss etc.?
4) What is your S3 model? (i9300?) and what OS version.

I've used the Samsung Infuse and also iBolt docks. Both have the split USB cable for charging & 3.mm audio.

I don't remember any noise when clicking buttons?
But we're talking about AUX input which is analog, so when you turn the volume up with no music playing, you'll always hear some "soft" occasional clicks & hiss.

AT&T GS3 with various ICS ROM's. I don't use AUX anymore because my favorite ROM (AOKP) doesn't have audio out capability when docked.

Thanks for replying Eddie. I am so sick of this troubleshooting this crap sometimes. I am very happy with the S3. It is a giant leap forward from my HD2...in most ways...but not all. I am suspecting the USB audio out on my S3 has a defect.
Right now, in the car, I have resigned to using the USB for power and the Headphone jack for audio send to the AUX input of my Sony car stereo on a custom wired Ibolt docking cradle. I still get some PROCESSOR noise when pressing the buttons but it is about 5% of the intensity of using the stock wired Ibolt, or KiDiGi desktop dock...or my hand wired Ycable. Without the USB charging wired up, there is NO NOISE whatsoever with either method.
Digital Output
Reading many threads last night, I discovered that with some roms/kernels, it is also possible to output pure DIGITAL audio from the S3 USB port into a select number of little affordable boutique like amps which decode and amplify the audio and power spkrs and headphones.
My first S3 had some weird noise when using bluetooth. So I drove over to my local corporate AT&T store and let them know. They walked out to my car with a demo S3 and we tested it and it didn't have any noise at all. So they swapped out my phone for a new one and I've been happy ever since.
Maybe you could try that?
Regarding boutique amps... this guy in one of my threads was talking about that. I didn't understand half of what he said.

Yup that's it. There are a few examples on youtube. Interesting how it's this TRADE SECRET feature. I mean, I have not seen this advertised anywhere and the places on the net where I found examples....the guys talk about it as if it's this common well known feature. Apparently, next to having one of these setups, the Iphone4 has the the best rating for sound/volume/curve output...almost neck to neck with a dedicated DAC...I think they call it!
I bet if I spent another $100+ bucks for one of these amps, and ran it in my car through a power Inverter (12v to 110v inverter), that I could run the Digital signal out without the interference of my USB analogue out issue. But, I am past that now.
Thanks for your input Eddie!
DAC direct solved this problem for me with Siyah Kernel.
This also happens when you are charged with a car charger and using the line out.

Arkanius...are you saying...
1) You had the same terrible noise when charging in a car.... with usb audio analogue into aux input of car stereo?
2) and that you hooked up a DAC to resolve the car noise issue? If yes, would you mind sharing the DAC model with us and the cable used?
Although I may be digging up an old thread, it may be worth looking into (Currently majoring in Electrical Engineering and having completed two signal analysis classes).
themadproducer, were you able to get a spectrum output of the noise? If it just a set of static frequencies, a cascading array of notch filters may work out
EDIT: reading your mention of the USB charging, its quite possible that if the voltage converter is of cheap quality, the transistors involved in the voltage conversion from 12.0-14.0 Volts DC down to ~5.0 Volts DC may be giving off Radio Frequency noise, with the noise being picked by the audio cable due to physical proximity, akin to cross-talking in network cables ( a form of mutual inductance)
