It's great music x 6 with the CDX-P680 6-CD Changer. You can control it with many 2009 or previous Pioneer "IP-Bus" headunits (consult the headunit's owners manual for compatibility) and the headunit's remote control. This changer plays CD Audio, CD-R, and CD-RW discs, and has an 8x oversampling filter and a 1-bit D/A converter for clean, powerful music. Its memory can store the names of up to 100 CDs, and it mounts in multiple angles (vertical, horizontal, etc.) to best suit your vehicle.
