The Kenwood DDX8019 is yet another contender for your all-in-one in-car device dollar. The in-dash system plays CDs, DVDs (audio and video), MP3 discs, WMA discs, and USB audio sources out of the box. With add-on modules, it can be used to play satellite and HD radio and as a Bluetooth hands-free calling interface. Despite all this, however, its touch screen interface leaves something to be desired for playing media. Check our slide show and full review to see what we liked and what we didn't with this system.
