KJam Microphone switches off when connected to car stereo - 8125, K-JAM, P4300, MDA Vario General

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,

how to enable microphone while

is there any way to enable build-in microphone while using 2.5mm audio jack connected to car's stereo?any registry edit?Thanks in advance!
I think that the insertion of a jack into the socket operates a hardware switch so I don't think there can be any software tweaks. It is the same as plugging headphones in to a radio etc. the insertion of the jack breaks the connection to the speakers and diverts the output to the headphones.
I got a 2.5mm 4pole male to 3.5mm 3pole female adapter with built in mic and volume control off ebay for less than £5. A cheap 3.5mm patch lead to car stereo later and it works perfectly, other than a slight alternator induced whine is audiable when charging. This is more likely to be from my cheap car charger as it goes when not charging. I like the way MP3s etc get muted when a call comes in. TomTom, Mortplayer and phone calls all at the same time, I love my Wizard.
Guess u didn’t try it. I have my wizard attached with the car stereo and when I get a call i can receive it and talk, the mic gets activated auto. Works perfect for me. Give it a try should work for u.
didn't try what?how does your mic work?
Well I use a 2.5 to 3.5 mm converter which in connected via RC wire to the car stereo linein, when I get a call I just receive it and I can talk. The music stops I can hear the person call and can talk back, the microphone works perfect.
with mine 2.5->3.5 mm jack(done it myself, the 2.5mm jack has 3 poles, not 4) can only hear but the other person doesn,t hear me
my jack has 3 poles, bougth it from ebay some time back, works perfect for me

Aux jack/ bluetooth

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!!!

wired headset?

Hi chaps,
Do you have any suggestion for a wired compact headset to take phone calls?
I got a bt but its not always on and when I get a call, I dont want everybody around me to hear the conversation but when i pop in a 3.5mm stereo headphone, the microphone stops working
I cant find a combo in-ear headphone microphone thingi with one 3.5mm jack or a mini usb headset... so any suggestions?
What about the original one in the package?
You can leave your device in the pocket and accept or quit phonecalls.
You can set the volume of the incoming call to lowest with the slider left to the navi-stick, then other people do not hear your calls if you are 2-3 meters away.
I'd like to know a wired headset which shows the caller-ID in the microphone case, like the old sony walkman with the display on the wire, showing actual song and volume. The 3.5 jack will not support this, i know.
yeah you can just leave any 3.5mm headphones pluggged in, as long as they are plugged in before the phone comes in you can use the inbuit microphone.
The device still rings, so you just put the buds in your ears and answer.
This is what I do with my senseinhers.
I'd like a decent replacement corded set, don't like the sound quality from BT ones I've tried.
Had a USB one from gpsforless that you can plug your own headphones in just past the mic, but it wasn't well built and lasted about 3 weeks.
I bought this one for use in the car while plugged into my AUX in on the car stereo.

It works great with the Athena, there are a bunch of different types on ebay, just search for "Tytn Adapter" and you will find a bunch.
Pretty much any HTC Extended USB based adapter will work with the Athena.
Good Luck

I don't have such a problem with the original wired headset. The sound is excellent in both WM5 and WM6.
My wired headphones died pretty quickly, so now I use a pair of sennseisher buds, the microphone on the athena works when using standard earbuds, so although not hands free, it is at least a bit more private.
I like this from PPC Techs.
http://www.pocketpctechs.com/main.asp?unit=HTC_Advantage-895&area=accessories&item=PPCPADPT17
It gives you both 2.5mm and 3.5mm output so you can have your headphones in one plug and the headset in the other.
They have another adapter that goes from the USB for the same purpose but I don't have that one.

but maybe causing malfunction the microphone ?
thanks a lots, i will try to change my earbud,

[Resolved] Question re car stereo, aux and bluetooth

I have a feeling that this can't be done (because I looked into it with my XDA Exec a few years ago), but....
Is there any way that I can play mp3s via the extUSB into a car stereo (via an AUX in) and yet answer calls via the same stereo's integrated bluetooth via the headset profile?
The stereo would normally drop the AUX in sound for a bluetooth call, but clearly the extUSB would normally handle calls if a audio output device is plugged into it. With my Exec, I seem to remember that the hardwired audio output would be the default, and so the bluetooth would never engage.
If there is a hardware solution, I would be very keen to know! Even better if the extUSB also charged my Vario IV in a passive holder.

What about playing music through the blue tooth of your car stereo? Tricking the car into thinking its actually engaged in a call so it plays music. Might have to be something done on the phone side to transmit the music as a call and then when you receive a call the music stops and you can answer the call and when the call ends music resumes? Just a thought i dont know if it is possible at all. But you bring up a really good idea.

Thanks for the thought, but the stereo doesn't accept bluetooth streams - it simply just has the ability to act as a hands free device.
Any more thoughts anyone? (Although someone has just posted about a device that looks intriguing with AUX and power in)
It's definitely doable. Thats what I've done with my non BT Pioneer deck. Check out my post here - http://forum.xda-developers.com/showthread.php?p=3278241#post3278241.
Hope this helps.

Thank you too for the feedback, but I can't see a bluetooth device in your chain. Perhaps I wasn't clear in the original post, but in the end I suppose the question is can calls be handled over bluetooth when there is any audio outpu device plugged into the extUSB?
Sorry. My bad. You are right, I did misread your post.

the answer is yes. that is what i do daily.
i listen to music through quality wired headphones, and when a call comes in i use my bt headset WITHOUT unplugging the headphones from extUSB.
all you need to do is answer the call using the answer button on your bt headset and not your phone.
in some phones, if you will press the send key on the phone and not the bt headset, the call will transfer to the phone instead of the bt headset.
hope i was able to help.

Do you think it matters that you're using headphones rather than a headset? I'm just wondering, since you refer to headphones, if the lack of speaker in your wired device means the call will hand over to the BT device - this will allow me to work out what I need to buy.
hmm i think since your aux input wont really have a mic attached it should hand over the call to the bluetooth headset from what the other person is saying.
Hi, I don't know if this will apply to your stereo setup but I thought I would let you know my setup anyway.
I use the HTC multifunction audio cable http://www.expansys.com/p.aspx?i=171925 which lets me charge my phone via a car charger and use the 3.5mm audio output to the stereos aux input at the same time - all of which are in center armrest compartment.
I use bluetooth connection to the factory installed bluetooth prep (BMW 3-Series). When a call comes in the TP pauses the audio and the BT phone then takes over. When the call ends the TP un-pauses the audio
I just installed a Blaupunkt MP57 on Sunday and did exactly what you're describing. Phone connected via aux playing music, answer or make calls via bluetooth on the stereo and the music pauses then restarts when the call is ended.

Both can send all outgoing audio from your WM device via BT headset channel instead of A2DP. It's not advanced audio but it will let you play audio over the headset BT channel. Sound can be tweaked using SRS WOW HD.
ExtUSB is just a port which will enable playing MP3 tracks on for example USB drive? Why not put your connection in USB mode then?
I'm not sure if this will help you, but I bought a Motorola Bluetooth Car Kit. I don't have the "phone" feature built into my car Stereo, so I used the external amplified speaker and mic for "phone" functions. The Car Kit has an Aux Out, with I feed into my car stereo. When I get into the car, the Bluetooth initiates two separate "connections". One for the "phone" and one for the "MP3 Player". You can have either one or both. The music plays through the car stereo (via the Aux Input) and phone calls play the the external Car Kit Speaker. It is like having two independent bluetooth "channels". When I have Voice Commander enabled, it communicates through the "phone" channel, i.e., the Car Kit mic and external speaker. That is also where my incoming email is announced through. My Garmin GPS "speaks" through the Aux out and the Car Stereo though. I'm not sure how these routes are selected. Personally, I would prefer that the GPS also communicated through the "phone" channel, that way if I am listening to the Radio, or Sirius, or a CD (not on AUX-IN), I would still here the GPS voice guidance. I'm not sure if that can be changed or not.
Hope this helps.
I do this all the time. USB to 3.5mm stereo to Pioneer head unit and calls come in over the BT
Thanks all for the input.
Just bought a Brando adaptor:
http://www.inkino.co.uk/zen/index.php?main_page=product_info&cPath=126&products_id=1502
Tested it and Copilot and Music run from the Aux out. Bluetooth hand over perfectly. As an aside, I find WMP is a better MP3 player, simply because I can reduce the volume in the software, but leave Copilot to use the system volume at a slightly higher level so the voice doesn't get lost (the HTC player doesn't seem to have the same capability).
Could have bought the HTC branded device from the same place, but the main lead from the Ext USB is slightly longer and more inflexible so wouldn't easily fit under my car holder.
BTW, since I live close to the shop (plus I love instant gratification as opposed to mail order), I visited the Inkino shop in London. I must say that the staff were very knowledgeable and helpful and the shop has a huge range of HTC accessories (including a branded battery and extended battery for my Universal, which I am planning to resurrect). Not sure about the prices vs ebay, but for the bricks and mortar approach in the UK, where it is difficult to find anything HTC - 1st class!

Handsfree calls using headphone jack + internal microphone

One of the features I miss of my Hero that my Nokia N95-8GB had was the ability to plug in a standard pair of headphones (or 3.5mm audio out cable) and use the built in microphone to make hands free calls.
I use the phone a lot in my car whilst driving to and from work to listen to music and would love for it to recognise the standard cable (which it does - indicated by a pair of headphones rather than the headphones/mic icon used to indicate the presence of the hands-free headphones) and be able to automatically answer inbound calls using the internal microphone.
Is there an app for this kind of thing - I'm guessing it is something that is/can be controlled by software?
have you tried it actually? because i use my ipod headphones quite often and it works as expected, sound from headphones and i hold phone closely to my mouth as its using internal mic.
Really not sure what you are looking for. If you plug the standard HTC headphones in using the jack on the top then you can use of the built in mike they have to answer calls.
Or have I missed something?
I've also done exactly what you're asking with my car. I've had my phone in a car holder w/ an audio cable from the Hero's headphone jack to my car's line in jack. I was able to answer calls just fine, and the person on the other end could hear me. (And it was just a standard stereo audio cable, my car doesn't have any sort of built in mic)

im doing the same thing but people on the other end are complaining about an echo of thir voice. I figure its coming from thier voice being picked up by the internal mic. Anybody have any ideas? how can i cut the internal mic while theyare talking. would a cheap wired headset work using its external mic? i could cut the headphones off and splice it into the line in.
I have had my G2 since late September and quickly found out by accident that it does use the internal mic when a headphone is plugged in.
Mine is a simple adaptor from the 3.5 mm into the RCA in my car. If I have the volume up too high, it echoes. If I have the volume down low, I can have a perfect handsfree conversation.
With the headphones I have had problems. In the car, I have the phone laying down and the mic side up. If I am holding the phone in my hand, I have no problems. Shirt pocket, ok. Pants pocket, no way.
