@ m.r. davis - Nokia N78, uses similar software to the N96 if that helps.
It's flakey at the best of times, but it does pair if I do it manually, by going to the Telephone/BT Audio setting and manually connecting, however, if I don't do this my phone just beeps constantly saying "Disconnected" and the head unit does naff all. It occasionally won't connect either, I dunno if it's the phone or the head unit to be honest.
I'm not bothered at all about the BT Audio since that's only slightly less rubbish than the FM transmitter built into my phone (lol), but I managed to get on the hands free last night and it seemed really good (if not overly bassy through the speakers!) - so it'd be nice to have that on there anyways.
Really dumb question, how do you answer the phone on it? Someone called me, I pressed the phone button on the far left and it disconnected the call, lol
