You could use a B1 to stream Bluetooth audio in your car if you use USB power from either a cigarette lighter USB power adapter or USB port, and your car audio has an aux 3.5mm input. You can then pick up a RCA to 3.5mm adapter for the connection and the B1 will be ready to pair to your device/play through the car stereo. Let us know if you have any other questions.
How can I connect the B1 for my car audio?
