Pre droid I had my HTC xv6900 paired to the 2010 Camaro's stereo and also an iTouch paired through bluetooth for playing my music. When I made a call with the onstar button the stereo would mute the iTouch and dial the phone number using the cell phone.
I would like to have the same ability with my new droid x but can only get it to pair on the phone side... sort of. Now the only way to get it to go through my cell plan with it paired is to dial the phone manualy. If I use the onstar button it uses my onstar plan. Anyways... I would the Droid x to work through the Onstar Automatic bluetooth dial button. also...
Has anyone had luck setting up / playing music from their droid with GM cars? I assume I can't have it paired twice but if I delete the pairing with the "phone + Stereo" setting and attempt the "phone + GPS" pairing it still does not allow music. It just connects it as a phone. If I really had to choose between the two i would choose the music.
