Main highlights
- [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.
- [HiFi Sound Quality] Despite its compact design, the Roadtrip is packed with two internal 3-watt speakers. Unlike other Bluetooth car speakers on the market, the powerful dual 3W multimedia speakers provide high fidelity sharp sound quality and louder call volume so you can hear voice from a phone call over ambient background noise.
- [Crystal Clear Calls] The powerful 3-watt dual speakers enable you to always hear your conversations clearly and the built-in dual microphone with noise reduction technology provides the ultimate call clarity for both call and caller – whether you are dealing with freeway or traffic noises.
- [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 Roadtrip’s built-in motion sensor will detect your presence, power on, and automatically connect to your device as you open the door.
- [2-in-1 Car Speakerphone & FM Transmitter] The Roadtrip functions as a handsfree Bluetooth car speakerphone for taking calls with your smartphone with the ability of Siri Assistant to make calls, send texts or get driving directions. Secondly, use the Roadtrip as a FM transmitter to send call audio or music to your car stereo system by setting up a vacant FM channel.
