Yes, it crops up from time to time. In my case, I am not able to run a 4.0.4 version of CM9 or I lose BT Audio streaming to my Toyota. I currently run the 4.0.3 version from 3/18 and it works great.

Several others have posted various problems with an array of manufacturers, while a larger portion report that everything works great.

I have seen this same phenomenon since my previous phone (Captivate on CM7), and it seems to change over time with versions, ROMs, radios... nothing consistent I can point at and say THAT IS THE PROBLEM.

However, after just looking at your thread in the Sprint section, we are not talking about the same problem I suspect. I never have any trouble pairing the device, and in fact my stereo will show the connected icons fine. It just wont actually play audio, though the phone portion still works. That is what we usually see here (I think), and jives with my past experience too.

I suggest getting into the BT setup screen on your phone, and just before your stereo tells you to "use your phone to connect", hit the scan button so your phone is actively scanning when the stereo starts broadcasting. I have had the phone seemingly not scanning in time, and erroring out instead of asking for PIN, but doing the above seems to help.

Good luck.

It's an odd issue.

The stereo is always 'visible' to other Bluetooth devices, so all you do from the phone is search, and if your in range, the phone finds it, you tap it, and its 'supposed' to prompt to enter PIN on the phone, but instead, it's like the phone is simply sending a default code and trying to pair automatically. I'm assuming its tossing '0000' out there, and then erroring because the stereo's default is '1234'.

Has to be a BT profile conflict with 4.0.4 & my particular Kenwood stereo, the BT language is just not communicating properly to initiate the PIN prompt.

I will have to check my stereo if I'm able to manually change the PIN code it's programmed with... if i can get it to be '0000' i believe my phone might pair...

Maybe... :-\

Only reason i have this stereo is for the Bluetooth feature, i would hate to have to upgrade it just to 'try' and see if a newer stereo can handle the phone's newer BT profile setup..

More $$$$$ ya know?

Keep an eye out for an update to 4.0.4 too. Issues like this were also back in the GB days, and updates would change things. Not always for the better either, at least not for everyone. It always seems like someone is having BT problems of some sort, with some device, while others are ok.

Not pairing at all is a new one on me though.

Did some quick searching and found this thread about a Droid RAZR with the same problem. This guy fixed it... give it a shot.

I have a similar problem. I connect with the Bluetooth phone in my Nissan Maxima, but I have to manually connect to my Bluetooth stereo gateway. I think the problem is that my car Bluetooth PIN is 1234 and the stereo gateway is 0000. No way to make the PINS the same. I believe that is what prevents my GNex from connecting to both automatically. I don't know if it is a software fix or faulty hardware design. I have a Razr Maxx and have the same problem with it as well.

mine connects to my JVC stereo but the music cuts out every min or so for 1 second then resumes, it also sounds like a cd skipping sometimes and I am using google music so I know it is not the case :)

Fixed mine. I was able to change the PIN on the stereo, however the actual problem was the stereo had four previous phones still paired in memory, which I've now found out is its Max. So it wasn't even attempting to allow another device to pair.

Once I deleted all the previous devices from the stereos memory, and tried to pair the gnex, it prompted for PIN like normal.

So glad to have this feature again!
