This is all foreign to me so go easy on me. I have been totally unsucessful in finding a fully functioning hands free car kit that can work with the bionic. Main issue is caller ID. Someone calls that is in my address book and the name is not said by the car kit device. Tried 2 different droid roadsters. Nice device but doesn't live up to it's advertising. I have spent hours with tech support - Verizon Store, Verizon call in tech support, Motorola support(what a joke that was- sent right to the Philippines). Since Motorola made both the Bionic phone and Roadster hands free, voice activated car kit, all functions would work. But it didn't. The Roadster was nice in that it played through the car stereo system. Any ideas or solutions out there?
