KJam Microphone switches off when connected to car stereo

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,

Decent sound in car?

Hi, I have an XDA Serra, very pleased with this phone so far, the only downside is battery life, but hey I can live with that.
I am using it in the car for Sat Nav (Co Pilot 6) or in car holder for calls on the move.
Unfortunately the sound generated from the handset speaker isn't great and therefore I would like to be able to either use a car holder that amplifies the sound, or use the phone through the a car stereo.
My current stereo is pretty basic so I am looking to change it for a Bluetooth model, however I would like to know what works and which model to buy (not too expensive).
I would like to be able to 1) hear phone calls 2) run co-pilot 3) play music through the car stereo. Is it possible to do this through a BT capable Stereo? anyone got this working succesfully?
Cheers, Blair

There is another issue with the sound: as the speaker ist on the back side of the phone, most car holders will cover the speaker, so the volume goes down. Same happens when you lay it on the table.

re
dark_lobito, thanks for your response, I must admit I didn't pick up on that at first, just checked my car kit and it appears that the speaker is not fully covered, but is blocking some of the speaker.
I bought this http://www.expansys.com/d.aspx?i=169986 which is OK for the price, and gives enough sound for a quiet room indoors. It's not amazing but is good enough for using as a portable radio/music player, but not in the car.
I have been looking and there are quite a few car stereos with BT audio streaming, as well as phone capabilities. But I need to know if it works as I want it to before splashing out.
I am hoping somebody has got these functions working with a BT Car Stereo to advise me.
Cheers, Blair

My car has an Auxilliary input, so I used the adapter that came with the phone and plugged the charger and Aux In wire to the phone. That sends the sound through the speakers of your car.
Also when you use the adapter that came with the phone it lets you use the microphone also so it works perfectly.

re
samz465, thanks for reply, but I'm not sure what u mean? The only adapter I got with the phone (O2 XDA Serra version) was a cable that allows u to connect to a 3.5 jack.
Sorry to be a pain, any pictures showing what adaptor you mean?
Cheers, Blair

Can I jump in here?
I have the HTC Pro too (Sprint)
I also have a car with an IPOD input
Well tonight I connected that to the phone's dongle via the 3.5mm input.
It sounds so good with my speakers ..BUT when I connect the USB headset that came with it, and make a phone call, they can't hear me but I can hear them just LOUD
Am I doing something wrong?

You might want to check out the Motorola T605 - Bluetooth hands-free car kit. It has stereo BT profile and an FM transmitter.
Might save you the cost and installation of a new head unit.
I've never used the T605 so I can't vouch for how good it is.

i've bought a car kit fm transmitter from ebay & made a quick review of it here. it works ok but you can only charge it if you don't use the fm transmitter & vice versa, it does not have a speaker unfortunately... does the job ok otherwise. decent/good enough sound for GPS & even for music playback

Too get better sound you should also try SRS WOW HD. It boosts volume and certainly clears up the mumble. Voices are recognizable as voices instead of monsters coming out of a can.

[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.

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.

Thank you.
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!

hands free device

has anyone tried using your d.i. through the car speakers while talking?

On my SYNC equipped Ford it works fine once I downloaded the phonebook to the car...

I didn't bother and just use the built in speaker which is loud enough. I'll have to link it in to the stereo to see.

Okay so , Right now with my mt3g, I can hook it up to my car stereo via the mini-usb to 3.5mm adapter that it came with(it has a microphone on it),and I can make calls and hear people through my speakers. With the Inc. am I going to need another kind of adapter or will the speaker on the phone itself be good?

I found this out accdentally, but using a regular stereo cable from my DI to the car's aux input, I was able to hear calls through the speaker, and they could hear me via the phone's built in Mic. I was surprised the first time I heard it ring, but it worked very nice, no issues that they couldn't hear me and the sound quality was top notch. I really like how it will mute whatever else is playing in the meantime, like Slacker / Pandora, and continue once the call is over.
Hope this helps.

Mic not working with MyTouch/Pioneer CD-BTB200 Bluetooth Wireless Adapter

I just installed a Pioneer AVH-P4200DVD head unit in my car with the CD-BTB200 Bluetooth Wireless Adapter.
Everything with the CD-BTB200 works except I can’t be heard by the person I am calling through the mic. No static, distortion - just nothing. Friends I call just can’t hear me, but I can here them.
My phone is a T-Mobile MyTouch Android 2.2.1 and it pairs and registers just fine CD-BTB200 Bluetooth Wireless Adapter.
Streaming A2DP Bluetooth music works fine from the phone. I can dial out and receive calls (and hear this through my car speakers).
I can hear the person on the other phone through my car speakers but they cannot hear me.
I have tried resetting CD-BTB200 by pushing the reset button with a pen, plugging and unplugging the mic from the unit and making sure it is secure, erasing the CD-BTB200 from my phone and starting from scratch, connecting and re-registering to the AVH-P4200DVD.
Everything works as described before except the mic.
Anyone have this problem? Any thoughts or a work-around?
Wondering if this is the CD-BTB200 unit, the mic or my phone.

same problem here
hey! i have exactly the same problem here...
mine is a DEH-3UB and my cell is a samsumg galaxy 5.
i was having the problem with 2.1 android. now i updated to 2.2 and the problem persists.
i was just about to go to the store where i bought the sound to have them checking the cable connections... but i think i will try with someone's iphone just to make sure it's a physical problem...

Maybe SoundAbout can help, it sure helped me with my problem I thougt it'd never be fixed
