I have noticed that when the code associated with the car does not match to the phone it will connect and then drop when the code can not be verified.

And when you say "code" are we talking about the BMW code that it requests when initially pairing the phone with the car? Or are you talking about some other code?

The phone knows it is paired with the BMW it just fades in and out of connected status. This seems to be very common with HTC android phones and BMW. If you do a google search on the topic there are tons of threads on other forums about BT connectivity and HTC/android phones. Which leads me to believe it is an HTC matter not a bimmer matter.

Someone one of the threads was uttering something to do with the HTC-android phones don't talk to the SPP bluetooth we have in the BMW.

I am still running 2.1 on my HTC desire (Orange UK) in my E46 (330 ci) and never had any problems synchronizing my address-book with he car. I get the occasional connection drop if, when I attempt to call someone, I hang up before they answer the phone or it goes to answerphone. Apart from that it works OK. Some people on an android forum though seem to have problems synchronizing their contacts, most of these people have trouble with contacts that have pictures. Mine are all OK, even the ones with a picture. Just a though. Are your contacts google contacts, phone contacs or sim contacts? I only have phone contacts.
