The Griffin 9501-TRIPCB is the most versatile iTrip to date, accommodating every dock connector iPod, including the iPod Nano and 5th-generation iPods videos. The iTrip Auto uses the audio line out from the iPod's dock connector and optimizes the output volume, allowing speaker volume to be controlled solely from the car stereo controls, without having to adjust the iPod's volume level. This unit features all the innovations of its predecessors, including selectable LX and DX modes for best-quality audio under real-world conditions, best-possible RF technology, and Griffin's world-class industrial design.

The Griffin iTrip Auto is constructed with a built-in FM stereo antenna and a high-stability crystal oscillator with phase-lock loop control. This unit can operate anywhere from the 88.1 to 107.9 MHz frequencies, with a frequency response ranging from 50 Hz to 15 KHz, at a range from 10 to 30 feet. The 9501-TRIPCB is powered by an included 12-volt cigarette lighter power adapter that features an easily replaceable fuse through which it also charges your iPod. This unit comes in black, weighs 0.6 ounces, measures 0.49 x 2.84 inches (W x D) with a total length of 33.47 inches including the cord, and it's backed by a manufacturer's limited 1-year warranty.
