The Bottom Line: The Cobra XRS 9960G offers a feature set that goes far beyond standard radar detectors. Its detection performance works for most people, but it may come up short for faster drivers.

The Bottom Line: For people who listen primarily to MP3/WMA/AAC audio, the Alpine iDA-X305 offers one of the easiest-to-use interfaces for in-car browsing of digital media.

The Bottom Line: Stylish, easy to use, and accurate, the TomTom XL 330S is a great all-around GPS but we wish it was just a little cheaper.

The Bottom Line: The Navigon 2200T takes some time to warm up but the GPS offers a lot of bang for your buck, including free traffic updates for life.

Specs: Automotive, Navigation instructions, Street name announcement, 4.3 oz

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: While there is much to like about the Motorola Motonav TN30, buggy software limits its usability.

Specs: Automotive, Audible signal(s), 6 oz

The Bottom Line: For users who spend much time listening to broadcast stations that offer HD Radio, the Alpine TUA-T550HD's increased sound quality and functionality make it a worthwhile addition to an Ai-Net compatible Alpine receiver.

Specs: HD radio tuner, HD radio

The Bottom Line: The Alpine iDA-X100 is a great receiver for people who transport all of their music on an iPod or MP3 player. The unit offers fantastic digital-audio integration without the need for a separate adapter, but should you ever want to just play a CD, you'll be out of luck.

Specs: Radio / digital player, Radio tuner, USB, Audio line-out, Audio line-in

The Bottom Line: The Navigon 8100T offers an impressive feature list, including panoramic 3D map views, but the GPS doesn't deliver where it counts most: performance.
