I'm not sure how the radio is setup to receive the phonebook. I have gotten a Sony and Pioneer car radio to accept the phonebook from a Galaxy S Epic (as well as do in-dash calls and audio streaming on the Sony, still trying to iron out the Pioneer). So it's possible, but do you know if your radio is set up for Android or iPhone capabilities, or both?
How do I cope/transfer my phonebook t6o the car? It's"looped" when I'm paired but not transfered meaning on the harddisk. When sking for phonebook even when paired and connected I get the voice saying "phonebook is empty".
