It's not your cars ladies and gentlemen, it's your phone. I have a set of Motorola bluetooth headphones that I know function normally, (with my very much missed iPhone,) but as soon as I put my Galaxy in my pocket it drops the headphones. Pull it out, push play and it plays until the phone goes back into my pocket.
I believe the Galaxy S II has a very weak Bluetooth signal, very weak!
I didn't read far into the forum as no one was offering any fixes, just issues.
I'll cross my fingers and hope I'm not stuck with this piece of crap for another year, 11 months, and 11 days.
