I ordered a Griffin RoadTrip to replace my iTrip (which doesn't work with my video iPod model). The RoadTrip arrived this morning and it's already turned out to be a great accessory. The unit incorporates a power supply and broadcasts on radio frequencies and the iPod sits up nicely when you plug the RoadTrip into the vehicle's cigarette lighter. In fact, it's even easy to watch videos while you drive--a dangerous distraction, no doubt.
