RoadTrip Handsfree is Griffin's complete automobile solution for iPod and all Bluetooth-enabled smartphones. RoadTrip holds your iPhone or iPod securely in place on a flexible steel neck in a cleverly-designed cradle that accommodates most cases (so you won't even have to take your iPod or iPhone out of its case). RoadTrip uses a powerful FM transmitter to send the music wirelessly to your car's FM radio so you and the whole car can enjoy it through your stereo speakers. And while you're enjoying the music your iPod or iPhone is enjoying a battery-charge. You can also use RoadTrip as a handsfree speakerphone in your car. RoadTrip's built-in microphone picks up your voice and your caller's voice plays through your stereo speakers. RoadTrip's handsfree phone features work with iPhone and other Bluetooth-enabled phones. Griffin innovations and user-centric design make the difference: like SmartScan a Griffin feature that finds the best FM frequency and performs the setup for you; and user-definable presets that let you save and recall the most useful FM frequencies with a single button push; and Griffin SmartSound that analyzes the signal and adjusts the output to make sure your music sounds great. RoadTrip even puts track controls at your fingertips. Play pause skip tracks forward and backward from RoadTrip's buttons and your eyes never have to leave the road.
