Failing for me. Droid Charge (my third!), Nissan LEAF.
My OG Droid and my wife's Droid 2 Global both work perfectly (I haven't tried music playback with her phone, but it's fine with the old Droid).
With the Charge, it'll pair, but upon receiving a call, it'll drop BT audio, which made me think the call was dropped, but it wasn't. Comical for the folks on the other end, who could hear me fussin' and cussin' while I tried to figure out what was going on, but I couldn't hear them.
I've tried the workaround to kill the pb service, which seemed to work...except that I couldn't get music playback to work when I tried it last night. Which may have been partially due to another Charge problem, which is that the SD card becomes unusable for media playback: You can see music and video files, but all players refuse to play them. Played havoc with a custom ringtone I was using--calls would come in silently, 'cause the ringtone couldn't be played. After my BT music playback attempt, I noticed I couldn't play music at all (or local videos). A reboot fixed that. I'll try the BT music playback later today, see if it's OK now.
This phone could be great...if it wasn't so buggy.
EDIT: Playing music works (except for the occasional skip) when the "kill the service" workaround is used, and when the SD card hasn't gone missing.
