Can i tranfer audio through BT to my mercedes BT HFP? - Windows Mobile Development and Hacking General

well the title is clear, my car Mercedes Benz take my Advantage as its phone, i tranfered my contacts and i dial and talk using the car, i was thinking maybe instead of burning the songs i have on my advantage i would just play them of the advantage using the phone system and speakers of the cars, so far i tried audio toggle which works fine with my jabra to transfer sound from and to headset but when connectect to my car it does't work, now i noticed that while the music is supposed to be playing from the car, and i dial any number i get the music appearing for a second from the car system before it actialy starts ringing on the other side or what where, which means if there is a way to suggest to my car that its actually calling someone while its not it could play music from my car system, can anyone scratch there head with me, also know the services found on the car are Handsfree BT profile not more

Looking for a good aftermarket car stereo to use with Titan bluetooth

I'm considering putting a new stero in the car but if I do I want to get one with bluetooth that will work with my XV6800. Does anyone out there have one that they are happy with? Handsfree dialing, access to contacts and streaming MP3s to the stereo would all be nice features to have.
Try Sony radios?
Me and my wife have the Sony BT2600 each. Reasonably priced below 200 and will bluetooth phone and stream audio as well (she has the Instinct and I have the htc 6800). You can't upload contacts to the radio but it will use the voice tags stored on your phone. The radio has a built in mic with abilty to adjust mic level from low to high. I love when I stream mp3's/listen to radio stations, the radio cuts to the phone and then resumes when u hang up. The phone's ringtone doesn't play through the speakers. Instead, a series of beeps play through the speakers alerting you to the call.
My wife's phone/audio connects to the radio automatically when her stereo is on. Mine, however, will connect the phone automatically, but I have to manually connect the bluetoothed audio. Not a problem though, all I have to do is press button 6 on the stereo and it will automatically connect the last device. For a budget stereo, I don't know what I'd do without it : )
Best Buy does have some Bluetooth stereos (that's where I got ours) but beware. Some stereos are bluetooth ready and need an adapter/accessory to bring bluetooth functionality to the stereo.
I had read a few reviews of the Sony units where people say that people they are talking to through the stereo couldn't hear them well. Some of them thought it was because of the placement of the microphone on the stereo. Do you not have any issues talking to people through yours?

[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.

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!

Mobile GPS and Bluetooth Car Stereo

Any of you use a gps program on your phone? If so, do you also have a car stereo with bluetooth? If so, do any of you know if it is possible to listen to an ipod or a cd while the gps interrupts gives you instructions every now and then. I'm asking because I'd rather not have to always listen to music on my phone, just to have the gps also going though the speakers.
I have Tom Tom 7 on my HTC HD2 and I also have a Sony BT3700 Headunit in the car.
I have used navigation many times when the phone has been ready to receive a call and I have also used the phone many times without the navigation switched on.
The other day I was using tom tom and somebody rang me but at the time I had the voices on mute, so I do not know about the sounds.
I have never had the chace to be on the phone and use TomTom voices as well.
I am pretty sure what will happen, is the sound for the phonecall will come out on your stereo and the sound for GPS will come out of the phone.
I believe that is the best way and I would have no problem with that.
If you want to use the GPS voices over bluetooth, you will need to use the bluetooth overaudio function which you would also use to play a song or watch a film.
Hope that makes sense?
Well I have the Xperia x1i and tom tom navigator 6, as well as a dual xhd7720 with the bluetooth adapter. What I want to do is play my ipod while I have the gps navigation going. The only way I can have the music and gps playing through the speakers is to tune to Bt streaming on my radio and have the music playing from my phone. I would just set my phone to have the gps voice go through the phone speaker, but those with the Xperia should know that the speaker isn't very loud.
I understand what you mean now.
But I believe it is not possible. The problem is not with the phone, but with the headunit. You can not listen to BTaudio mode and ipod or CD at the same time.
It would be like trying to listen to the radio and your ipod at the same time on your headunit, just not possible.
My onyl suggestion is by some cheap speakers to plug into the bottom of your xperia for better sound? and keep using the btaudio mode for the phone.
Just to clarify at bit more. What I'm looking for is a way to trick the head unit into thinking that whenever an instruction is given (such as turn left in a quarter mile) the head unit mutes the music, much like it does when there is a phone call. I figured that would be something software could take care of on the phone.

Does anyone have a problem to link x10 to a car hands-free and audio system?

Just got my x10 few days ago.
was trying to link it to my car via bluetooth.
I have a 09 mazda 6
the bluetooth hands free and aduio works well with my previous device, which is x1.
but for x10, it shows that link is successfull, but when i play the music, there is no sound comes out from the car's speaker at all.
so then I tried with hands free, so i make my frd to call me, the display of the car does show the number, but when i picked up the phone call, my frd's voice wont come out from the car's speaker as well, it comes out on the phone's speaker, during the main time, both car's mic and the mic in the phone, wont get my voice, my frd didnt hear anything.
my other frd, which owns a 09 arcura tsx have the exactly same problem with me.
does anyone else have the same problem with me ?

I have the same issue with my connectors in my car (mercedes benz 09 12V) hands-free and stereo syncs with the X10 but does nothing at all. I think this is in particular a bug to be fixed with the Android update. I dont really mind since I use the car´s system to bump it up.
hopefully the 2.1 will fix this, thks bro.
Connection to car audio system via auxiliary cable
Hi, I am new to the forum and this is my first post.
I tried to connect my X10 via auxiliary cable to my car's audio system and I am able to hear music through my car speakers but if I want to use this method to call someone I can hear the ringing and the other person through car speakers but they cannot hear me, even if I speak directly to the phone's mic. The only way they can hear me if I unplug the auxiliary cable from the phone. Does anyone know if there's a solution to this ? Thanks,
i have nissan 370z touring with bluetooth. works fine my with car. shows phone number and i can place calls and receive calls fine.
Hi - I've got a few bluetooth options - A retro fit bluetooth kit integrated into the car stereo for my work phone - which work with my X10 too.. A sun visor mounted blue tooth kit.. which works fine.. and a jabra bluetooth headset.. which also works fine.. !!
Sorry for that.
The bluetooth works for me very well in my car. Renault Megane '09

Hi
I connect to a Parrot 3100 with no real issues. I did get better performance when putting the latest firmware on my parrot.
The issues I DO have is from the key lock. If its on, I have many issues with phonebooks, answering calls and ending them.
cheers

To fix this you need to plug in the sony adapter that came with your phone, then plug in your auxiliary cable to that adapter then your car system. The x10 doesn't recognize mic that aren't manufactured by Sony, so they have to pass through the adapter for someone to hear you on the other end.
I am trying to use my x10 with nokia's bluetooth carkit 7w. I get an connection, then it disconnects, shows its connected on the top of the screen, but i'll be buggered if it is. I have to reboot the phone to get it to connect, and then o repeat the sequence of events. If this is a compatibilty issue, can anyone recomend a carkit?
X10 connected to Toyota Prius hands-free with no problem. But turn on X10's bluetooth before turning on your car.
Sound like most of you guys showing off your car more fine
My bluetooth have the same problem (chrysler pacifica 06) and locale suck as i have to flip on the phone for bt to turn on.
It is 50 50 chance it pair up for me

Bluetooth Car Stereo

Finally got bluetooth in my car stereo and reviewed some threads prior to posting, but not sure anyone asked / answered the question I have. I'm basically wondering how people are using their bluetooth stereo's. From what I can tell so far I have 2 options.
1. Phone pairs, i listen to my car stereo and if a phone call comes in the stereo picks up the call if i say, and upon completion back to my car stereo
2. Phone pairs, put the car into BT Audio mode and stream audio from my phone including phone calls.
The problem is, i'm looking for a way to combine both. For example I'd like to be able to listen to my car stereo, and if i get a notification i hear it over the radio, not just phone calls. I haven't tried yet, but i'm guessing the nav will be the same way, if i'm listening to the stereo and running nav on my phone i will get no turn by turn like i would if i was listening to music on my phone and running nav.
Is there a way to do this? Am I missing something? I have the Sony Xplōd™ MEX-BT3900U. Is this a limitation of my stereo, or just not how most people use their bluetooth?
I just ordered a replacement radio as well with BT support. I'd be curious wth what other people have to say with experience as well.
I use this all the time.
Both options will work provided the head unit you bought supports media streaming.
Your phone will connect both phone and media over Bluetooth. You listen to your media and if a call comes in you can take it while the media is paused. Media will resume after call completed.
Notifications and navigation will pause and resume media as needed.
Sent from my NookColor
I've found the quality of the audio over bluetooth to be very degraded. Have a rear AUX 1/8th port and run a cable to mount, Then use BT headset for all if need be, but have Pandora playing Excision & Downlink radio the entire time
