Griffin Technology's iTrip Auto
The iTrip Auto connects to the dock connector on your iPod which means it has access to the line level out on the iPod. The iTrip Auto then optimizes the output volume so you can then use the car stereo volume controls to do the rest. You won't have to mess with the iPod volume controls.
The iTrip Auto includes a large backlit LCD display to make it easy to see what FM station you're setting the system to transmit on. There are also selectable LX and DX modes for best quality audio under real world conditions. The best part? The iTrip Auto works on any dock connector iPod.
