I'm having real issues establishing and maintaining the bluetooth connection between my HTC Hero (1.5 Rooted) and my Pioneer Car stereo. It is a DEH6000UB with a BTB100 Bluetooth adapter which is plugged into the IP Bus. I usually have to search a good 3 or 4 times from both the phone and the head unit before I can establish a connection and then am lucky if it lasts 5 minutes before it drops out. When trying to play Bluetooth mp3 audio, both the phone and head unit recognises the connection but I can't hear any music. I have made and received a few phone calls using bluetooth so it is obviously not totally incompatible. Is there anything I can do to help stabilise it all? Predictably, I tried it on a Nokia and everything fell into place straight away.
