The Bottom Line: The Panasonic CQ-C8305U performs the basic functions of a digital-age car stereo well with great audio-tweaking options, intuitive file and folder navigation, and a worthwhile iPod interface. The stereo's full-motion color display adds little to its usability or attractiveness and its Bluetooth is disappointing.

The Bottom Line: The Jensen MP66312i provides an impressive range of media inputs, standard Bluetooth connectivity, and a usable iPod interface. Its low-rent display lets it down, but its impressive number of features is difficult to beat for the price.

The Bottom Line: The Sony MEX BT-2500 is a good option for those looking to spend no more than $200 on a Bluetooth-enabled in-car stereo. Its straightforward design and intuitive controls make it easy to use, but its limited calling capabilities and poor outgoing sound quality let it down.

The Bottom Line: The JVC KD-BT-1 offers a hatful of features for its price. However, it can be tricky to master all the controls, and you'll need a seriously tricked-out phone to make the most of it.

The Bottom Line: The made-for-iPod Alpine iDA-X001 is a useful interface for bringing a digital-music library on the road. We like its stylish design and breadth of functions, although its user interface falls behind that of the iPod itself.

The Bottom Line: The Sony MEX-BT5000 is packed with useful entertainment and communications features, although it suffers from some fiddly controls. Advanced Bluetooth audio streaming may be its star feature, but its built-in sound optimization for digital audio playback means that it is more than a one-trick pony.
