Ok i have an iphone 3gs and a kenwood head unit in my car and synced my 3gs with no problem. I can listen to music, make and hear calls just fine. The only problem that i just noticed was when listening to music via bluetooth through my head unit and lock the phone or it locks by itself the music kinda skips and and cuts out. Soon as i press the home key or the lock button to where the "slide to unlock" appears the music kicks back in and plays perfectly. I did this several times just to see if it was a fluke or not, and everytime the phone LOCKS it cuts out.

Any ideas?

PS. I had an ipod touch 2g and could stream music via bluetooth with no problem locking the ipod at anytime did not effect the music at all.

Thanks alot!
