OK, so your vehicle still has a factory stereo. All you have to do now is to add a Pioneer CD changer, like the CDX-FM1277. It's a 12-disc changer that works off the FM signal in your existing stereo, giving you hours of CD, CD-R, and CD-RW play. The CDX-FM1277 can be mounted in various locations and comes with a wireless remote and a control/display unit.
