Instead of building its own car stereo, Apple has started working with car companies to make cars with built-in iPod compatibility [source: Stevens]. Some of these stereo systems allow you to control the iPod through the stereo's head unit or even through steering wheel buttons. Although you may buy a new stereo to fit your iPod, you may not be able to buy a whole car for that same reason.
Until you can purchase one of the recent generations of iPod-compatible cars, you can settle for a car stereo built with iPod compatibility. A few stereos have emerged that do this. Alpine was the first company to develop iPod-compatible stereos that you can control through the head-unit. You can shuffle through your library using stereo controls and even view album art on the stereo's LCD screen.
However, some users get frustrated with the Alpine models' lack of a good dock for the iPod itself. To answer these demands, Fusion introduced an iPod-compatible car stereo with a face that opens and provides a hidden dock. This might be the best option for someone who wants to get rid of clutter completely.
No matter what accessories you buy to integrate your beloved iPod with your car, make sure to check their compatibility first. Certain accessories apply to specific generations of iPods only.
