I thought Bluetooth was always backwards compatible...that 3.0 (phone) would always be able to connect to a 2.0 device?
I haven't tried going all the way back to DL09 or DI01 and seeing what happens. I've spent SO much time loading ROMs trying to find the answer that I'm ROMd out. At this point it sounds like it might the only way to further trouble shoot it.
I've tried using EB01 stock (including bloat) and a voodoo....and non voodoo. I'm on Adrynalene's now...2.4 I believe.
To attempt to further explain the issue...I can be streaming content (Slacker, mp3s, podcasts), then get a call, hang up call and the content tries to start again but then stops and then I get the "force close" vibrations with no force close message, and both the phone and stereo think they are still connected when they are not.
I can also not be streaming content (just listening to the stereo)...and take or make a call, and upon disconnecting the call the stereo resumes playing audio but my phone still ends up with the force close vibration sequence with no force close message.
