Hey guys, I bought the official samsung/verizon car dock for my charge the other day for a 4.5 hour trip I was doing, and while the built in power/audio ports on the dock were great....the audio out on the dock always lets out EAR PIERCING squealing randomly. if I plug my audio cable into the headphone jack OTOH, it works flawlessly.....
Anyone else use the dock and have similar issues? also, im sure this is from my cigarette socket...but charging like to randomly drop off and on >.<
Other than that, if I plug into the headphone jack versus line out on the dock it is great...albeit annoying
I will have my car dock from VzW tomorrow and will test this out.
It sounds like it could be a ground loop. Do you hear the the sound change when you rev the car engine? What about when the engine is off?
Ok, so I seem to have figured out the problem with the squealing audio through the line-out on the car dock.....the leaked GB roms are to blame so it is. I tried humble and gummy GB roms and the speaker blasting squealing was there, then went back to Froyo and BLAMMO no more squealing.
just food for thought hehe
EDIT....*grumbles* nevermind, started squealing like a stuck pig again this morning....PITA but oh well, not that big a deal, so I have to plug the audio cable into the headphone jack instead of the oh so convenient line-out jack on the official car dock.

I just got my official car dock the other day. It works fine, but one problem I have with it, is when my phone is in the dock, it causes noise/feedback on the auxiliary in to my stereo(which is hooked up to the n1). If I pop it out of the dock, it's fine, no noise.
Anyone else experiencing this problem? Any fix? It's pretty much at the point where I don't want to listen to music on the phone if it's plugged into the dock....

A friend of mine (@gIMpSTa) told me it's caused by the car-dock power supply (cigarette lighter) sharing the same ground with your car-stereo...Which makes sense..... Change the ground wire on your stereo or cigarette lighter and you should be good to go!!
yep, its alternator noise caused by a poor ground, could be the lighter port or could be in the engine bay. I would suggest just hard wiring the charger which is what im gonna do when i get the car dock.
I should be able to hardwire it anywhere I can find 5v? It only draws 2 amps if I recall, so that shouldn't be much of an issue...
Hey guys, would this solve my problem?
http://us.kensington.com/html/14484.html
I wouldn't think so, since it's still being plugged into the same adapter, but just thought I'd check
I got one of these yesterday:
http://www.amazon.com/Google-Nexus-One-Retractable-Charger/dp/B002W52DVK/
I was playing some audio through the aux jack connected to my car's speakers. As soon as I plugged in the charger, the audio was distorted. It sounded very electronic/mechanical; hard to explain. As soon as I unplugged, the audio went back to normal.
Is this how all car chargers operate? Or is this one defective?
Does anyone know of a similarly priced car charger that doesn't have this issue?
your car audio system and charger are sharing ground. I don't recall the exact solution...so search forum... solution is on the forum.
EDIT: I just remembered... change the ground on your car stereo.... just attach it to some other metal piece.

Sorry, attach what?
Not too knowledgeable about car stuff.

your car audio system should have bunch of wires in the back. Look in the user manual, one of them will be "ground wire". It is either attached to the "ground" wire coming from your car or just attached to nearest metal piece. usually a screw etc... in the vicinity of the audio system. Just remove the wire and attach it to some other metal.
If you don't want to mess with your car audio, do the same thing to charger outlet. try to locate the wires coming into the charger outlet. One of them is ground. change it's location.
If you are not too comfortable with this, just as your car mechanic to do it. it is fairly easy if you already know which wire is what... so it should be an easy task for him.
So all car chargers with the N1 will behave this way?

Lord I hope not, I was in the market for a good car charger too..

the problem is not with N1 but rather with the electrical arrangement in a particular car. I do not have this problem,but, unfortunately for paul, all chargers will cause this interference.
Isolate the Ground!!! It's not rocket science, and it sure as hell ain't the n1....
So there's definitely 0% chance that it's the charger and getting a different one wouldn't make a difference?
I tried just plugging in the power, without any audio playing, and the speakers play a lot of metallic interference garbage. Unplug/plug in, plays weird sounds every time.

Try this to know for sure:
1) don't connect charger, and play music through car speakers
2) use charger and play music through battery powered speakers
Both should turn out ok.

A ground loop is simply an antenna formed by the cable from ground, to your phone (charger), to your radio, and back to ground. The noise you're hearing when you don't play music is random noise from any and all radio waves that might pass through this giant loop antenna.
Think of all the stuff that emits RF noise: ignition/sparks, power supplies, phones, BT, wifi, electrical mains and poor connections. All these faint signals are picked up by your giant ground loop and amplified by your radio.
There are also some audio ground loop isolators, but I don't know how well they work.

I know this thread is old and dead, but I just wanted to thank arkavat and xdZKu7 for their answers. I've had interference since I got my car and plugged my DHD into the aux in, and it's been driving me mad for ages. The sound is crystal clear until I plug the charger in and then I get some nasty alternator whining. I searched and found this thread last night, today I went with arkavat's answer and I found the cigarette lighter's ground wire and earthed it nearer by, now the alternator noise is gone almost entirely. I'm going to look into what I can do to reduce ground loop antenna noise also, although it's bearable for now. Thanks guys.
I bought the "official" OEM HTC micro USB CC C200 at amazon.
And it works fine. No problems with audio and navigation so far.
For those of you that have one. Please dock your phone, play a song and put on a headset. Listen to the quality of it. Now unplug your headset and plug it to the headphone port up on top. Hear the difference?
Its night and day, the port on the dock not only sounds low but there is no bass. Or is it just my dock? Please check your dock and let me know.
Thanks in advance.
anyone? Can you test please?
If you have a case on the phone and if the jack on the car dock is standard size, it might be too thick to go plug all the way. If it is not plugged all the way you will experience the symptoms you just described...
Hate cases so its in all the way. do you have the car dock? if yes can you please try and check to see if the sound is the same at the car dock verses the top port.
I am not sure if anyone checked it (I know the thread is one year old), but I have the same problem. Actually I stumbled across this thread because I wanted to know if there are some settings I can play with, so the sound out of the microusb is the same with the sound out of the headphone jack on top of the phone (my car has an aux input where I can plug a 3.5 jack.
Thanks for helping

I picked up the car dock and desk dock for $11 with my corporate discount. I downloaded the sound redirector app from the market and things were working great.
However, with the desk dock I noticed that I get crackling every time the phone is plugged in. If I unplug the charger the crackling goes away. Does anyone else have this problem? Also the sound is very hallow and tiny. There is almost no bass, and it not just my headphones, because the audio is much better if unplugged from the dock and plugged into the 3.5mm jack on the phone. I like the option of these docks, but this is a big bummer for me.
Anyone whose car dock audio port works? Where you can plug the audio cable into the dock and the phone's audio (Pandora) would come out of the car speakers?
If so I'd like to know what ROM you are running. On my GummyCharged GBE 1.5 I have to plug the cable in the phone itself to get audio out to work.
go into settings/dock settings/ there you check off Audio output mode. That should force it to use external speakers. Just a heads up your phone call audio will NOT go through external speakers if you use the line out jack....dunno why >.<
Let me know if you get pig squealing through your car audio....happens to mine regardless of GB rom or Froyo...think it may be ground looping but it works fine through the headphone jack.
Let us know!

I wonder if that external speaker setting will effect Car Dock Home v3 also.
Okay, it now works through the audio port on the dock. I'm not sure if this is the pig squealing you're referring but, but there is a squeal when there's no audio being played, like between tracks on Pandora. But once audio is engaged the squeal goes away.
lol no, for me as soon as I attach it it goes "WEEEEEEEEEEEEE GARBLE BARBLE TSSHSSHHHHHHH" at like 100db >.>
scares the **** out of me hahaha

But do you hear it once music is playing? The squeal is constant for me as well when the audio plug is inserted. Once music starts it goes away, and I'm not talking about the music drowning out the squeal either, it goes away as if another signal takes over.
ya, it would come in and out randomly regardless if music was playing or not. I think its just a pesky ground loop cuz I do not get it when plugged into the headphone jack, only the line-out which shares the power. I'll do more experiments.
ok I just figured something out....the squealing only happens when the car dock mode is on....when I disable it on the phone it goes away. will be doing more testing to make sure it was not placebo
Awaiting for details then, the troublesome sounds I hear are related to the power plug, not the audio plug.
ya, i imagine that too, BUT even with the power disconnected from the port, and only having the audio cable hooked into it and my head unit, I would get the piercing, and i mean PIERCING, squeal. but as soon as I turn off 'car dock mode' it goes away. weird....

Have you tried different car dock apps?
My brother thinks something like this may solve the problem: http://www.amazon.com/Kensington-No...7?s=electronics&ie=UTF8&qid=1311182929&sr=1-7
He has a HTC one I will be borrowing to see if it solves the problem.
The audio filter thing took care of distortions when no sound is playing. One thing that does piss me off though is the I'm having to plug the AUX from car directly into the phone instead of the dock since Voodoo sound does not work when not plugged into the phone's audio port and it makes a huge diff in sound quality (with Headphone Amplifier set to 0dB from default -10dB).
