It's at least 6 times better than single CD. The CDX-P686 6-disc CD changer is compatible with many 2009 or previous Pioneer's "IP Bus" headunits, and plays 6 of your favorite CD's, CD-R's, and CD-RW's. It remembers and displays the name of the last 100 CD's it's played, as well as your special track programming. The CDX-P686 mounts in a variety of locations and angles in your vehicle, and you can control it via your Pioneer IP Bus headunit and remote. The Premier two-year warranty applies.
