I have a iphone 3gs everything works great, music, movies etc... but i can't get the phone to stay connect via bluetooth, it connects and then disconnects every time, i have tried it with the cable plugged in and with the cable unplugged. I have also turned the phone off, reset bluetooth and repaired it. Any help let me know please thanks!

Do you have any BT hacks on your phone? If you do, disable the hack and see if the problem goes away. If not, try pairing another phone. If the problem goes away there is likely a defect with the BT radio on the phone and will need to be replaced.

not sure why but next time i went in the car it worked thanks for the quick response
