I'm seeing some weirdness with my HD2 when I connect the headphone socket to my car's stereo (via an aux in that I have soldered onto my head unit). Basically, as soon as the jack is connected, the phone resets itself and then works perfectly until i disconnect the jack (when it resets again).
I know the connection to the car is OK as I've tried it with other phones and MP3 players, but for some reason, the HD2 doesn't seem to like it.
Possibly worth mentioning that the phone is also connected to the car's handsfree kit via bluetooth, but this doesn't support A2DP so need the headphone output for music. Also, normal headphones seem to be OK, it's just the line in that doesn't appear to like!
Anyone else seen something similar or (even better) have a solution?!
Thanks

Hi,
I have connected my KJam to my car stereo via a cable from the 2.5mm jack to the aux port of my car stereo. Tom Tom voice and phone calls are routed through my car stereo. Sometimes, the microphone will not work when I take a call. I can hear the caller perfectly but they can't hear me. Other times, the phone functionality works perfectly and we can both hear each other great.
If anyone can suggest any ideas, I would be very grateful.
Thanks
if your using a jack to connect it to your car, then its will prob. stop the mic working as its routing the audio to you car in the same way the headset with mic that you got with the k-jam does. I had this problem on mine, but due to the fact that i use a bluetooth neadset in the car fixed that little problem 8)
That's the end of my k-jam desires then.
I use my MDA compact in the same way you describe, for TomTom, Hands free calling and to play my music through.... and my microphone works fine with the headphone jack in.
I guess one thing to check would be the number of rings on your 2.5mm jack. If you have 3 then theres a possibility the k-jam thinks you have a mic on the end of the wire. If you have 2 rings (normal stereo headphones) then there must be another issue somewhere.
thanks for your replies. My concern was around the fact that sometimes the microphone works and sometimes not. I wonder if there is a workaround or a specific type of cable that I need to ensure that only the audio is routed and not the mic as well.
Thanks for all your help.l
never tried this myself, so i can only assume it would work. you could hack a cheap wired headset up, removing the earpieces but leaving the microphone. then add a stereo 3.5 plug so you can hook it up to your car stereo.

I have that very problem also, it's gotten that annoying that i've stopped using it through my stereo. you are able to get around it by popping the cable out of the kjam, then putting it back in.
pain in the ass though none the less.
What is the phone is set to Speakerphone ?
Even though Speakerphone is currently not working...
Hey all,
Just wondering if anyone has had any success in fixing this problem? I am having the same issue. I have a 2 ring 2.5-3.5mm adapter connected (so it should only be routing the audio, not the mic) and sometimes the caller can hear me, sometimes not. At one stage I found by unplugging the cable, setting to speakerphone, then unsetting speakerphone and plugging the cable back in would get it to work, but not anymore...
Any ideas?!?! I love my XDAII mini but this is driving me up the wall!
Cheers,

I need some help I have a U-Connect in my car and a PCC-6800 Mogul Phone. Here is the problem, when the phone is plugged into the Aux Jack of the radio for the use of the MP3 on the phone. The U-connect will make the call and hang up with-in seconds. So from what I can tell, when the phone is plugged into the radio its seeing itself plugged into a headphone mic jack and will not let the Bluetooth work correctly. (I have the same problem if I am in the car using a Bluetooth headset for phone calls and the phone plugged into the Jack for MP3. In another car.) So my question is this does anyone have a reg hack to fix this problem. And or does anyone know how to or which pin I can removed in the jack if that’s possible? Thanks!!!
I have an 8525 and I have an external FM transmitter which has an USB input. I am trying to go from my 8525 to the transmitter so I can listen from the handset on my radio. When I plug in the factory headset I get sound out of the headset. When I plug a mini USB into the same place the sound still comes out of the handset. How can I switch the sound to the USB so I can port that to the transmitter and hence to my radio and eventually to my motorcycle helmet? I realize that there must be a trick or else when synced you would not hear a ring or when charging, but I can not figure out what it is.
What brand/model is the transmitter?
transmitter
The problem is not the transmitter. It works fine with my mp3 player. The problems is that when hooked up the phone still sends the signal to the onboard speaker. The plug will redirect only for the headset included not any other usb attachment.
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.

I Have an aftermarket Bluetooth adapter in my old crappy car which connects to my phone through Bluetooth and outputs the sound to my speakers through an FM transmitter. The phone audio streams perfectly to the car speakers, but the issue is that the person on the other end cannot hear me because my mouth is nowhere close to the microphone on the unit (which is plugged into my car's cigarette lighter).
Ideal solution is to use my phone's microphone instead of the aftermarket device's while still routing the audio out through Bluetooth. Is this possible? I am rooted and am willing to tinker around in areas of the phone no one should dare go...
I did some Googling to no avail. I've downloaded SoundAbout thinking it might be able to, but no dice.
Thank you in advance!
