OK, so you have a factory car stereo. We won\'t tell anyone, IF you buy the CDX-FM687: it\'s a 6-CD changer that uses your stereo\'s FM signal to reproduce CD sound (playing CD Audio, CD-R, and CD-RW). The CDX-FM687 has an 8x oversampling filter and a 1-bit D/A converter for superior audio. It comes with a remote control and a wired control/display unit that shows disc and track info, and it can be mounted in multiple angles (vertical, horizontal, etc.) to best suit your vehicle.
