If your car has a removable radio with the standard 2- by 7-inch single DIN opening, the Alpine CDA-9853 radio lets you play store-bought, MP3, and WMA CDs, connect Sirius or XM satellite radio by adding a $100 tuner kit, and play and recharge your Apple iPod with a $100 adapter cable. The touchpad-like GlideStrip under the Alpine's display lets you select choices found on the bottom of the multicolor display. Other buttons are small and impossible to read, except for the volume knob, so you'll be using the 12-button remote a lot.
