I doubt it's that important you have to bump the thread every hour or so.
Unpair both devices completely and repair them again. It might not be pairing both modes.
You can also see if HFP is enabled in the /etc/bluetooth/audio.conf file via the Root Explorer app.
I use music and handsfree just fine with my SGS2 and my cheap Panasonic head unit. If the 2 options aren't there under the bluetooth device, then it's a pairing issue.

I have paired my device several times in various cars and never had to do any special configuration. I've always worked fine for the first try.

Does your phone pair properly with other car based bluetooth?
If not, it may be the kernel.
I had successful pairing with my original dlev rom in both of my cars and intermittent problems answering or my the other side could not hear my voice. Solution was to switch the kernel.
Hope this helps.

to what kernel you switched?! that exacly my issue! please answer

If you're having that much problem with it, pick up wired headphones with mic (or use the ones that came with the phone). I switched from bluetooth to these and will never look back.

but i need to use bluetooth due to the car's speakers....
thats the whole thing...

Bluetooth is car is always a matter of luck to me.
Feling lucky because I can manage it with my SG2 better than with my previous phone, the original I7000 galay

well that info isnt really helpful

anyone else might help please?

anyone????????

Are you 100% sure the car player has compatible a2dp music streaming?
If so then both headset and media options should be available in the Bluetooth pairing options.

Did you ever solve this issue? I am having the same problems with the same deck and phone.
Cheers.

It is not the phone, it's your dash unit. You'd be better off contacting Pioneer or whoever makes your aftermarket unit.
My SGS2 has sync'd and made calls perfectly via BT since day 1 with my Nissan GT-R... everything is stock Nissan though.

[Q] Bluetooth not working on Galaxy Nexus

Bluetooth appears to be broken on my Galaxy Nexus I can discover other bluetooth devices fine, and they can discover the Nexus, and pairing appears to be successful from either direction. But as soon as I try to connect/transfer a file immediately I get a notification on the Nexus saying 'connection unsuccessful', 'transfer cancelled by user' (when I didn't cancel anything!) etc.
I've tried this with three different devices (my old HTC Desire, my wife's HTC Legend and my MacBook Pro) with the same results on all three.
Has anyone else run into similar problems, or does this sound like I've got a faulty unit and should send it back? Is there anything I can do to troubleshoot this any further? (I've not rooted the phone and its running the stock Android 4 ROM).

I wish I had an answer; just got my Galaxy Nexus yesterday; it won't pair with any of my bluetooth(s) -- they were all working fine in my Droid so I know how to pair. Any suggestions? Help!! Thanks

After further investigation, it seems it's just outgoing connections that don't work on mine. I can transfer files from other devices to the GN fine, just can't transfer from the GN to any other devices. Haven't tried connecting to a headset or anything like that as I don't have one.
I asked an acquaintance who also owns a GN to test it out on theirs and they experienced exactly the same thing - everything works ok except for outgoing connections/transfers.
I'm wondering if its a software bug if that's the case. If it were hardware related you'd have thought the whole bluetooth thing would be broken.

FWIW: I have been able to pair and connect via bluetooth with my car, with no problem. Downloaded my phonebook to my car via bluetooth as well.

Bt phonebook pairing
I'm having BT issues as well with my G-Nex on Verizon. Will connect/pair with my car, works for making/receiving phone call audio, but will not synch the contact list. Thus, cannot use voice dial in my car (Nissan).
Have searched all over the internet, no real answers. Tried to disable the existing bluetooth PBAPservice as suggested somewhere else - no dice, and it just restarts itself anyway. I've seen some suggestion about rooting the phone and replacing the PBAPservice which may be my next step. Hate to root a phone this new when I may end up returning it if I can't make this work ... sorta a deal breaker for me.
Anyone have any suggestions? Could my phone just be defective? Seems like there are a number of BT issues around, but I can't find anything "official" acknowledging the issue(s) ..
Thanks ...

I'm having a problem with my new GNex bluetooth as well. I'm using a Blackberry Stereo Gateway (an A2DP adapter) in my car and it -does- work, but only after I toggle bluetooth off and back on again. That's kinda annoying.
Previously I had been using an Incredible and it was working fine.

Having problems with Bluetooth as well. I have a BlueFusion unit installed in my car. Worked perfectly fine with my Droid X. Every time I got in the car, it just connected and calls and music both played over the stereo fine. Got my Galaxy Nexus paired and it worked great. However, whenever I get back in the car and the Galaxy Nexus reconnects, the audio does not work. It says it's connected, it plays with no audio coming out of the phone or the car speakers though. Tried re-pairing, no go. Tried bluetooth on/off, no go. The only way to get it to work, is to reboot the phone every time I get in the car.

Does A2DP work properly? And what sort of bluetooth device are you pairing with?

Same here, sending files works, receiving doesn't. Pairing with my bt headset also works fine....

I had this problem when I fist boot the Nexus and after the first boot of the update to 4.0.1. Reboot the phone, re-pairing the devices and everything is fine since then.

I can't even get my Nexus to pair with my car (Kufatec FISCON unit for Volkswagen). Just straight up error "unable to pair" when I try it. :/

And I have a problem as well. I did get it to pair with my PC but I can't send any files from my PC to Nexus (it works fine with Desire).

I have two Nexus (one is my wife's) and both car have Blackberry Bluetooth Gateways in them. In both cases I am seeing the same issue as the OP, the bluetooth will not connect automatically. However if I manually power on the bluetooth on the phone when the gateway is in connecting mode than they will connect. I never had a problem like this with previous phones.
Is there a official way to inform Samsung of this issue?

I'm also having problems with bluetooth on my Galaxy Nexus. I wanted to transfer files via bluetooth from my old Incredible 2 to my new Galaxy Nexus and it just wouldn't work.
Edit: A reboot appears to have fixed the problem.

I have this same issue exactly - and had this issue after a System Update on my Droid Incredible for a few weeks before I ended up buying the Galaxy Nexus. I had hoped the new phone wouldn't have this issue. Anyways, it also seems to happen when I take a phone call.
Scenario: I'm listening to music over bluetooth to my bluetooth audio enabled headunit in my car. I receive a phone call, and toggle the bluetooth off so I can take the call privately over my phone's earpiece. When the call is finished, I toggle the bluetooth back on and the phone will connect - however the music is playing, but no audio comes through the phone nor the speakers of my car.
I started having this -exact- scenario issue when System Updates started rolling out for Droid Incredible, and they added the options for "Phone Audio" and "Media Audio" under the bluetooth options. Before these System Updates, my Droid Incredible had worked perfectly with bluetooth audio in my car.

I am having similar problems with both my car's BT phone and BT audio.The phone through my car gets terrible static until I stop and start Bluetooth again, which is dangerous on the highway.
I hope it can be fixed with a little software update.

I have the same problem with new nexus galaxy, pairs well with car bluetooth audio, can hear a confirmation beep on car speakers but no luck in the phone. It just stays on paired but not connected. It doesnt allow to remove pairing and redo it untill rebooting the device.

I'm also having issues with the bluetooth audio in my car. I pair okay with my Sony Xplod head unit, then when I turn off the car and reconnect, the GN starts playing music through the internal speaker instead of the car speakers.

I'm having the previously mentioned A2DP issue as well. Everything connects fine but occasionally, no audio is heard via the deck in my car. Phone calls via bluetooth work, just no A2DP audio.
For those having this same problem, you can fix issue by toggling airplane mode on and off. This is quicker than rebooting (which also fixes the issue).
This has to be a bug. I'm running 4.01. Anyone having the same issue with 4.02/4.03?

Yes. I just got mine last night...ran some errands today. Paired fine in my car, can make and receive calls through the car's audio system, but no sound. I'm running 4.02. Tried this with my BT headphones and the same thing happens.
The airplane mode trick works, however. Thanks!
Hopefully this will get fixed rather quickly!

[Q] No sound from earpiece, but speaker and headset work fine...

My wife's Nexus started to act up here this morning... When she tries to make calls, the following condition exists:
1. No sound from earpiece.
2. Remote callee hears no sound from the microphone.
However, when she activates speakerphone, she can hear the remote party and the internal microphone turns back on.
When she uses a wired headset, she can hear the remote party and the headset's microphone picks up audio and properly disables the internal microphone.
I've wiped Dalvik/cache. No dice. Any ideas?
Update: Also, the Music player -- when played without any headphones attached -- has no sound, not even via the speaker.

Update: Re-flashing the ROM did not help. WTF is wrong with this phone?

Update: Tried an entirely different ROM this time.. same issue.
ALSO... using the Music player (or Winamp) will NOT playback any media through the speaker.

Update: Problem disappeared literally overnight!
But now it's happening with the haptic feedback... The vibration works when the phone is powered on, and when the power button is pressed, but not for anything else. The correct checkboxes are selected in Settings/Sound.
What the eff is going on with this phone?

you can try this

Yeah the app "works" but having to manually turn the screen off when making a call sucks.. I've had this issue with 4 different Nexus phones.. Asurion is getting tired of me..I know..I refuse to take an LG Spectrum or Lucid 2 in exchange for my galaxy nexus

Different bluetooth stack?

Hi everyone,
The bluetooth on my GSIII has been a complete failure. You can follow the saga here (http://www.benzworld.org/forums/w245-b-class/1662643-2009-w245-samsung-galaxy-s-iii.html), but basically it connects to my car and has no sound with the stock ROM and refuses to connect to the car at all with the AOKP JB build. It suggests an android problem, so I'm wondering if the bluetooth stack can be reloaded to reflashed with something different. If anyone has any ideas, I'm all ears. Thank you!

I have a problem with one of my Bluetooth devices dropping and reconnecting. Not sure why is just one. It works fine on an iPhone. I'm guessing your GS3 isn't the international version?

I'm having a different issue. it connects and stays connected, plays music but it doesn't list the song/artist info on my eclipse screen but the SG2 will..

Update: no change with the new kernel. The phones pairs but there's no sound, just as was the case before.

Try CM9. Bluetooth works much better with it. CM10 should have it fixed as well in a day or two.

Here's a 'six months later' update. My phone went through various android updates and I'm now on Android 4.1.1 (up from 4.0.4). The problem was still not solved, but instead of no audio, I now have one way audio, where people hear me but I don't hear them through bluetooth. I have also gone through a number of custom ROMs and kernels for my phone (including CM9/10 and AOKP) and nothing helped with the issue.
A couple of days ago, my girlfriend's HTC One X (finally!) got its Android update, also from 4.0.4 to 4.1.1. Her phone now works like a charm with the in-car bluetooth.
The solution I ended up with was a car cradle and a couple of NFC tags to control my phone in the car. My NFC tag that's stuck to my car cradle turns off WiFi, starts car mode, starts a car home app and turns my volume to max. All I have to do after that is connect the 3.5mm audio cable and I use my phone in place of the car's infotainment system. That way the phone integrates into the car as well and the only thing I lose are the steering wheel controls (they still work for volume).
My less technologically inclined girlfriend now has everything work auto-magicallly with bluetooth. So I guess all's well that ends well, but to anyone considering a US-spec Galaxy S III, watch out: the bluetooth issue is still not fixed. If bluetooth is critical, consider the HTC One X (but be warned: it has awful battery life!)

I have no issues with stereo Bluetooth and mono Bluetooth. Everything and everyone hears and plays fine. It might be an issue with your headset.

Colby. What version of android, kernel / rom combo are you using?? There's SOOO many people having problems with JB and bluetooth, regardless of rom or kernel setup.
If you're on stock... just nm then.

What's wrong with stock? I have no major issues with streaming BT from my phone to my Mazda 3 head unit, or to my Sony MW600 earphones. Even track titles work (the only thing that doesn't work is time display). In my experience, Bluetooth works best on the stock ROM.
Stock Rogers ROM (DLK4 - JB 4.1.1), rooted
KT747 (1/9/2013) kernel
CWM Recovery 6.0.2.3
PlayerPro Music Player
On my old Xperia X10, I had CM7 and had no end of issues with BT:
- Sometimes it would connect and there would be no sound
- Sometimes it wouldn't connect at all
- Sometimes it would cut out after switching songs
- It would stutter a lot whenever Wi-Fi was enabled (but I think that was a problem with the Xperia).
When I tried CM10.0 on my S3 I had similar connection issues, just not as bad. Also, the volume gain over BT was much lower, so I had to turn the car speakers way up. Stock 4.1.1 doesn't have any of these problems. The only problem I had was the audio switching over to speaker after turning off the car, but I fixed it.
Also, BT is apparently broken in 4.2.1 in general, not just CM10.1. Google confirmed a BT patch that works on the Nexus 7, due for release with 4.2.2: http://www.expertreviews.co.uk/smar...confirms-android-4-2-bluetooth-streaming-flaw
TIP: Don't forget to turn up the volume on your phone. I don't know how many times I accidentally turned down the volume and thought that it wasn't working. Now I have Tasker do it for me whenever I connect. :good:

4.1.2 has Bluetooth working use it everyday. (Stock and ROM.) Can't tell u which combo I use at a time. I flash a different ROM everyday. As 4.2.1bluetooth is broken expect for task's AOKP. He has it workingish.
Now as connecting to a car. Depends on what it connects as. And I've learned going to and from ROMs when u connect a source hit the volume up 9/10 times it works

Severe Bluetooth issues

Hey guys,
I'm having some pretty bad bluetooth issues, and my searches haven't really found a solution. When I attempt to connect my phone to my car headunit, my headunit shows it's connected and my phone also shows connected. But the audio still comes out of the phone speaker. After a few minutes it will disconnect and reconnect a few times, sometimes only showing headset connected and not media. Eventually the bluetooth just locks up saying "connecting...". If I turn off bluetooth on my phone, the stereo still shows it is connected to a bluetooth device. I tried to "forget" my device and re-paired, and the process seems fine except the phone never asks if I want to share my phonebook, so I assume something behind the scenes is already broken at that point.
This is a very new problem for me, and my bluetooth was working fine with this headunit for months now using numerous different ROMs from GB to JB. I was on AOKP JB build 1 when this started. I tried a full wipe and reflashed the ROM and still had the problem. I have tested this on about five other ICS and JB ROMs and am currently on CM9.1 and the problem is continuing. I also tried a different phone to make sure the problem wasn't my headunit and the other phone worked as expected.
Has anyone else had this problem, or does anyone have any direction for me to fix this? Thanks!

I have a similar problem with aokp jb, when it wasn't present before. The head unit shows my phone audio connects but the media audio does not connect sometimes. I would have to reboot my phone or fully disconnect my phone from the head unit and pair them again.. no real solution but it is slight work around and to say that you're not alone

Thanks. I've had to reboot or re-pair in the past every once in awhile, but neither rebooting or re-pairing is fixing the connection anymore. Anyone else had this problem? Are know if there is some sort of log I can find on my phone that might give some clues to why this is happening?

Problem Solved....
I tried my phone in a different vehicle, with a different headunit. No problems at all. I went through my head unit menus and found an option to clear all bluetooth data. I assume this clears all paired device information from the headunit. Everything works perfect now. Phone pairs fast, stays connected, and all functions are perfect. I hope this helps someone at some point.
