I just bought a new car stereo and it has a USB port and is iPhone compatible. When I plug my iPhone 4 in it works fine and plays the music and shows track info and all that good stuff on the stereo BUT on my iPhone it locks me out of any iPod controls. When I goto iPod app it just says accessory connected and doesn't give me any controls.
Is there something I can do to bypass this, so I can control the music from both phone and stereo?!?
