Like Griffin's other iTrip products, the iTrip Auto for iPhone connects to your vehicle cigarette lighter, and features a built-in FM transmitter that lets you stream your audio from the iPhone to your vehicle's radio.
The iTrip Auto for iPhone features "SmartScan," which seeks out and locks the best frequencies available as presets. It has a power switch with a three-color charge indicator, and saves four preset frequencies from 88.1 to 107.9. The transmitter has a built-in LCD display so you can see what frequency the device is tuned to.
