[Auto Power On / Off] For your ultimate convenience, when you leave the car and your Bluetooth device disconnects from the Roadtrip, it is designed to automatically power off. Upon returning to your car, the Roadtrips built-in motion sensor will detect your presence, power on, and automatically connect to your device as you open the door.
[Multi-point Connection] Connect two phones in the same car to the Roadtrip and have the option to take phone calls from either. So whichever phone receives the latest incoming phone call, you will be able to answer that call by using the Roadtrip speakerphone. It also allows you to connect two phones so you can use the FM transmitter and stream two different music playlists through your car speakers.
