This new in-car device for iPod nano seems worth trying. Produced by Griffin Technology, they have brought along a cassette adapter with Tune Flex. So, with iPod Nano's TuneFlex car adapters users play music from their iPod using the car's cassette-based audio system. Easy and simple, the Flex runs on 12-volt power from the car's cigarette lighter adapter.

It also supports uses of other accessories through the dock connector. It is available for $49.99.
