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.

 

I am running 3.2 MCR at the moment. Are any of the 2.1 unofficial ROMs quick enough to use day to day?
