google car dock - headphone jack noise - Nexus One Accessories

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?

I wouldn't think so, since it's still being plugged into the same adapter, but just thought I'd check

My solution to the lack of aux jack on the car dock.

I agree that having an aux jack on the Nexus One car dock would be pretty sweet, but it is what it is, and I wanted to move on... Here is what I did:
Nexus One (duh)
Nexus One car dock (...)
Kensington LiquidAuxbluetooth car kit: us.kensington.com/html/14484.html
Micro USB cable
Plug the Kensington L.A. into the accessory outlet, and connect the audio output plug to your AUX on your stereo. The L.A. provides a USB port to use for the Micro USB cable. (for charging)
Plug the micro USB cable in this port and route to your car dock.
Once you pair your phone with the L.A. place it in the car dock and setup the audio to be whatever combination you would like. I personally use the dock for calls (because the mic is better) and the L.A. for audio.
One accessory outlet, (no splitters) one wire coming from it to the dock, audio routed through the AUX in your stereo, and (IMO) really great call audio thanks to the dock and noise canceling, which still works with the phone in the dock...
Just sharing my experience, YMMV, IANAL, OMG, WTF, BBQ...

+ 1. That looks like a really good solution. Another benefit you did not mention is that by powering the Car Dock with the Micro USB cable, you do away with the spiral lead that is on the Car Dock power supply. So easier to route and hide.
Any issues with charging the phone and powering the car dock? Isn't the car doc charger higher output than regular chargers and perhaps the one on the LiquidAux?
how's the music sound quality?

No issues I have noticed so far, there is no additional <warmth> on the LiquidAux I have been able to detect, and the phone charges just as quickly as it would when plugged in using OEM adapter. And yes, losing the spiral lead is a nice bonus...

Sound quality for me is great, there is no interruptions, etc I have noticed. But I suspect that this would be a YMMV kind of thing based on the car stereo used and the distance / path (if that even matters with the relatively short distance) between the LiquidAux device and the phone...

Why yes, but some people in this particular forum were voicing their displeasure of having a mass of wires dangling all over their car / phone etc...
I was offering an alternative, and it worked well for me, nobody said or implied that you need to do it too...
<Sheesh/>
How long is that cable(the 3.5mm one from the liquid aux). Looks pretty short..

Hmm. I guess, worst case scenario, I can just buy a short extender.
Another question for you... Does the remote work with the phone? I'm waiting for mine to get here but I had read from many reviews that the control did not work properly with the iphone, just wondering if the nexus one had the same problem.
Sent from my Nexus One using the XDA mobile application powered by Tapatalk
awesome writeup... Even if this thing doesn't work to pickup calls I don't care, I always have a bluetooth headset for the car anyhow. I think I'll get an extra socket and mount it all under the dash out of sight.
Even thought you can plug in a wire to the headphone jack I want a solution where I can stick the phone in the holder when I get in, and pull it right out without messing with cables every fricken time... Most the time I don't plug my phone in right now just because of that very reason.
With a nice setup like this I'd plug my phone in every time I get in the car... awesome, Thanks!
Just ordered mine off amazon.. seems like a great price for the product.
Nevermind, reread your first post, missed the info I wanted the first read through. Well, since I'm stuck with this post existing, may as well clarify, you said you can choose to have the phone calls go through the dock with this, right?

4 inches, is that all you've got? - that is short
I think perhaps you meant 4' or four feet.

The media functions work fantastic with the Nexus, the iPhone does not support track skip, where the Nexus does. I have not been able to get the phone button to start voice dialing like the iPhone does. I have not actually had a call while driving to pickup yet, so I can't say for certain whether that (pickup incoming) works or not...

I have call audio go through the dock, yes. The LiquidAux has a microphone, but it is quite far away from the the speaker's mouth IMO. Additionally, the dock still uses the extra Michael for active noise cancelling and is quite crisp and clear for calls. (I have so far made several outbound calls with great results.) The music pauses, audio routes up to the dock for the duration of the call, then the music resumed on the car speakers automatically...

Car Charger - Interference with Audio?

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.

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?

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.
For information about ground loops see this pdf:

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.

problematic car dock

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.

Where can I a find Multimedia Car adapter?

So I'm in the planning stages to dash mount a Galaxy Tab 7.0 Plus (still haven't bought the tablet yet), and wanted to know where I could find an accessory similar to the Galaxy Tab Multimedia Dock. My goal is to have one connection that will give me both power and audio out to my stereo. The desktop dock can accomplish this for me, but its very bulky and wont be easy to fit in my dash. I could take the dock apart and make it work, but would prefer not to waste 35 dollars like that.
So far the only other item I found that may work is this RCA Composite Cable with USB, but it says only for the original and some of the reviews mention the cable not having the usb attachment as pictured.
Does anyone else have any suggestions?
Finally found it on Amazon after a few days of looking. 30 Pin to USB Charging and 3.5mm Audio Out
Just ordered it and will post pics of my finished car installation and let anyone else who's interested know if it works or not.

Let us know how you make out with this. I'd be curious to see if it's compatible with the 6210.
Both of the cables I listed work great. The only issue I have noticed is that at when the stereo is turned up you can hear interference from the power cable. When the music is playing you can't hear it at all.
As I mentioned, here is a picture of the final product. It's hinged on the bottom and clips into place with the standard mounting hardware. FYI it's inside a 2000 Nissan Xterra XE. The volume knob is where the second lighter adapter was. I just hooked in an inline volume knob to adjust the output from the tablet to the stereo. I replaced the included knob with one I ripped off an old stereo. You can barely see that I also installed an auxiliary input jack that somehow miraculously reduces the volume of the tablet when another device is hooked in. All of the "guts are stored inside the dash where all of the other wires are located. If anyone is interested I can post more pictures.
Thanks for the follow up. The final product looks very good. Nice work!
Nice install. Thanks for sharing.
Man, that cable would have come in useful when i was still direct-connecting my tablet. I'll have to keep that in mind.
Put a PAC SN1 inline with your audio to reduce your ground loop interference - that's what i used when i was direct connecting the audio.
Also have this set up on my dash, but I've jumped to the 7.7 and gave the 7 Plus to my wife. I actually prefer to use bluetooth to connect the audio because i can use the car's steering control to control advance/reverse of media.
I'm putting up pics soon of my setup in the 7.7 forum.

Thanks for the heads up. I was prepared to live with the interference because I didn't know I had a choice. I found a PAC SNI-1 ground loop noise isolator for 14 bucks on eBay. Can't wait to install it and get back to clear audio.
On a side note; after about a month with this tablet in my car, I have to say I'm in love. With the power plugged in and screen on while charging activated, the tablet turns on when I start the car, just like any stereo would. Also when I take it out at night it makes my car look already-broken-into and deters the motherlovin thieves that have been breaking into neighborhood cars.
By the way, does anyone know how to remove the annoying 100% charged sound? It can get especially irritating when I have plenty of stops to make and the tablet loses a percent and gains it back everytime I turn the car off and on again.

[Q] Dock for Car

Hey guys,
i need some help / ideas for the best solution for my "docking"-problem in my car.
I have a bmw and since there are no snap-in adapters for htc i have to go over audiojack for listening music with spotify and i can't just put it to the place where the audiojack is because i have to control music with the touchscreen (iDrive 1 so no bt-audioplayback/control...).
Now i got 2 problems:
1. the cable looks ugly when its plugged in the phone and
2. i have no idea where to place my holder because every place i put the ugly holder the car looks cheapy.
So, my idea is to go over the pogo-pins!
Yeah pogo-pins but i don't know the assignment of the pins so the solution would be the cr s650 dock.
BUT! i think i my car won't be able to provide enough power through usb (is it possible to power the dock with usb?!).
The plan was to place the dock (please see the attachment) in the red circle and put the cable under the cover to the usb charger and the audiojack.
And also i have to modify the dock so i can plug in a jack into the dock or just solder a cable or whatever...
So my questions are, do you think this will work? And what problems i will have implementing this? Any other better ideas maybe?
Thanks for help and sorry for my bad english i think
No ideas?

I have no idea about the pogo pin dock, but I would avoid making any permanent modifications to a BMW and deal with the ugly look...it will decrease the resale value...you could always take the dock down when not in use (which is what I do)
Regarding the pogo dock, Make sure that the phone stays still and will not fall off the dock with some hard driving.
Not the prettiest solution, but I use this: http://www.amazon.com/Mountek-nGroo...1131802&sr=8-1&keywords=cd+player+phone+mount
and just hard wired a power cable behind the dash (as to not have wires all over coming from my cig lighter)
The reason I went for that dock is because the phone is a lot closer and more accessible vs mounted to the windshield or elsewhere...also, regarding your proposed placement: having it down by the gear shift while driving would be pretty disorienting to me using GPS
