Car CD changers

The Bottom Line: The Fusion CA-IP500 iPod receiver's internal iPod dock is an interesting solution for taking digital audio on the road, but we've seen more elegant and similarly priced solutions from its more established competitors.

The Bottom Line: The Sony CDX-GT520 is a decent option for those wanting a reasonably priced stereo to play disc-based audio. While it does support HD Radio, it requires the connection of a clunky add-on module, which is almost more trouble than it's worth.

The Bottom Line: The Kenwood KDC X890 is a capable head unit that supports a broad range of audio formats. Voice indexing helps counteract awkward manual file selection, although the system's claims that it measures car performance are dubious.
