Today’s in-dash receivers do more than just play the radio and CDs. Case in point — Kenwood’s DDX271 receiver offers compatibility with many of your iPhone® apps, extensive built-in iPod®/iPhone controls, a bright 6.1″ touchscreen, variable color illumination, and an easy-to-use menu interface. Another big plus — if you’ve got Garmin’s impressive Street Pilot app loaded, you can display maps and directions on the DDX271′s screen while you drive with your iPhone4/4S connected.
