Connecting to car stereo

Hi
Just after some input on connecting to a car stereo. My thoughts
1) I have read the guide on creating your own mini usb to 3.5mm jack plug cable and have also seen similar things for sale
2) I have seen on a car forum for the car i own a guide for making a cable connecting 3.5mm jack plug to the AUX on the car stereo (used for the cd changer).
3) I can charger my kaiser through a usb cable in the car.
4) There is obviously a power source on the stereo.
Given the above, would it be possible in theory to have a direct connection between the phone usb and the stereo that would allow the phone to play through the stereo and also charge it at the same time?
I dont want to go through the process of doing it if there is some fundamental reason why it cant be done.

this might be wht your looking for hxxp://cgi.ebay.co.uk/3in1-usb-Adapter-for-HTC-KAISER-P4550-TYTN-II-VARIO-III_W0QQitemZ190232228190QQcmdZViewItem?hash=item190232228190&_trkparms=72%3A12%7C39%3A1%7C65%3A12&_trksid=p3286.c0.m14

Of course you could. But keep in mind that your microphone won't work for most usb+3.5mm adapter. It's very troublesome to pick up the phone. I would recommend you to opt for BT route. e.g. Stereo bt headset w/ 3.5 mm adapter like Sony Ds-220 or BT head unit like JVC BT-1

Something you might have to research is alternator whine.
I made a lead myself as you described. But as long as the device was charging There would be a buzzing coming from the speakers. This went away when running on battery power and when the device was fully charged.
I also tried a bluetooth device, and again if I tried to use it while it was charging I would get the dreaded buzzing.
I still have not found a solution. FM transmitters have never worked either for me. There is not enough space between channels here.

You can solve this by installing ground looping isolator if the power source from yr car is not clean

Hi.
I had the same problem, see my solution with the help of others:

Good luck.

Well I think based on what I have read and the replies on here I am going to give it a go.
I will update on here once completed

I have a bluetooth stereo in my cab and my phone connects to the stereo using the bluetooth, I am also able to use Btmusic and play anything on my phone thru my car stereo its great for the odd file just wish it would do video as well thru bluetooth.

The original mic supplied works okay for me with the headphones chopped, but its very echoey even mounted as far from my speakers as possible so would agree with the above.
Ive the same setup in my car. The phone stuff was easy, it was getting the right VAG adapter to fit my cars HU that gave me the most trouble.
I also hardwired in my charging cable to keep it tidier and my cig lighter free, might be worth thinking about.

I have made a start on this. I have wired in the cable from the Car stereo and at the moment this ends with a 3.5mm Jack Plug. I have also bought the YC A200 cable from HTC which allows connection of the 3.5mm jack plug, a wired headset and also mini usb charging. In fact two of the HTC cables were delivered to me (one ordered but 2 delivered and invoiced) so I might use one as a development cable.
So far - music plays through stereo ok, not over impressed with the quality so far but am going to fiddle with the settings. SatNav also plays through the stereo - much easier to hear. I have had an issue this morning when having music playing and satnav running that the GPS signal was being lost. Not sure if this is a problem with running the two things at once or an interference issue from somewhere. I have never had problems with the GPS before. Am going to do a soft reset and try again on the way home tonight.
I was looking at hardwiring the charging cable to tidy things up and free up the lighter socket. I was going to use the 12v feed from the stereo. Is there anything I need to do or be aware of on this?
How does the mic etc work? I know you can use the headset but I would prefer to use the car speakers if possible. We also have a number of old nokia car kits at work which I was thinking of using for the mic. Would the speaker side work if I connected the relevant cables from the headset port on the HTC adaptor to the 3.5mm jack plug connections?

Im just using the mic from the supplied headset, chopped off the cable past the mic/volume slider and mounted it in the car. Call audio comes through the car speakers.
To hardwire the charger in you need step the voltage down from 12v to the needed 5v. I took a live and earth from the back of the stereo, took apart a usb cig charger and soldered the cables into it, put it back together and hid it behind the dash. Then just took a mini usb cable from that up to the 3in1 plugged into the phone.
SRSWOWHD cleaned my sound up considerably using Pocketplayer.

Well, my experiences so far,
Got the HTC YC A200 cable
1) Playing music through car stereo works great
2) GPS works fine most of the time, still not sure what the problem is, mainly voice directions not working properly all the time
3) Charging via the cigarette lighter socket, still got to hard wire the charging
Latest development
Got a Nokia car kit mic, just had to trim the locking lugs off the 2.5mm (or is it 2mm) jack plug. The mic works fine and the caller can hear me ok. The sound comes through the stereo but is not as loud as the music but i can change this slightly by fiddling with the plug, gets louder or quieter but still not the same volume as the music.
Any ideas? Would it be that the HTC adaptor is expecting the htc wired headset?

removing alternator whine / hum
Finally solved the alternator whine / hum over at my place too. Key is to take the power for the charger directly from the power feeding the car stereo. That way both the stereo and charger reference the same ground which eliminated the ground loop and thus the alternator noise.

Stereo headphone adapter

Hi, i need to plug my htc juno to the car stereo. I have ma miniusb-headphone adapter but it doesn´t work, i think there should be an app that sends audio signal with the adapter.

i use the first sedio adapter and it works just fine.

[Q] hands free idea for the car

Ive been pondering this and thought i'd post it here for your general feedback.
the plug for the hearphone/mic headset that comes with the device is a triple pole 3.5mm jack - same thing used by video camcorders into the phono adaptors.
On the back of my car stereo unit ive an Aux in which would be the red/white plugs of this cable for the audio feed. This is generally how i'd plug my phone in to listen to my music.
Now with the 3rd wite (yellow) i was thinking if i used a small PC Mic (3.5mm jack) and get a patch cable made to connect this to a male phono would this work? it'd also give me the ability to hear my phone throughthe car, and a lengthy cable i can hide and place a mic in the car leaving a simple 3.5mm jack to plug into

[Q] Car audio?

My car does not have native bluetooth.
Right now what I use with my iPhone is a Kensington cigarette adapter-powered dock connector, that charges the dock and also has a line-out cord - so I charge + get audio out of the dock.
what is my equivalent solution once my android phone arrives? Is there any alternative besides:
USB cable + USB->cigarette adapter, plus a 3.5mm male-male cable
Edit: To clarify, my current car situation is:
NO native bluetooth support. Would either need something like a bluetooth speaker (sucks for music, okay for calls?) or a bluetooth to 3.5mm adapter
I have a center console which has a cigarette adapter and a 3.5mm female port right beside it... so this is the AUX for my audio. Thinking at this time, at least, I'd prefer to keep using this AUX input for my music...

I use this: http://www.amazon.com/Kinivo-BTC8-Bluetooth-Transmitter-iPhone4/dp/B003OTXBY6/ref=cm_cr_pr_product_top
Connects through bluetooth for media and calls. Then connects to your car stereo with either FM or 3.5mm. It also has a charger built in.

Do you want bluetooth audio or hardwired output to an auxiliary input on your car stereo? The latter will have substantially better audio quality.

If you have a relatively new Kenwood receiver, Kenwood offers an app in the Play Store that enables you to play music over USB. The reviews seem to be rather negative though, and I don't think it offers full control. I'll try it out in my car once I get all my music uploaded to Google, but I'll probably just keep using my iPod as it has full native compatibility.

there is only one correct answer to this thread

Also, it's a 2007 Honda Accord...

too bad. these pioneer head units are INSANELY good. the 2 USB connections to charge or plug in SD cards alone is worth the price..not to mention the bluetooth capabilities to remotely control pandora from your head unit or steering wheel controls

Then just connect the headphone out of the phone into the AUX audio jack. Note that you *may* run into ground loop problems when the phone is connected to the AUX jack AND it is charging from the vehicle's 12V, resulting in a possible range of hum and noise gremlins. If you do, power supplies with an isolated ground are available.

Based on your needs i think you're looking for something like one of these. Stream from phone to car via bluetooth and output via mini-stereo to car AUX port. They each work a bit differently and have different features, so i'd compare them and see which suits your needs.
I should note, to charge the phone, you'd just need a separate usb charger or cable.

No mic when 3.5mm audio cable is plugged.

I connect my phone to my car stereo using a 3.5mm cable. but then when i try a voice goodle search, the phone doesn't pick up the sound. Only when i unplug the cable.
Any fix for this?

I had a similar issue with my Moto E2 a while back. Turns out that the 3.5mm audio cable I was using was designed for both input and output, so the E2 was identifying it as a headset, not headphones (my car's audio system does not have a mic). I bought another 3.5mm audio cable that was advertised as just audio output, and it worked as intended (output via audio cable to car speakers, input via phone's mic).
