“iPod” is a lineup of digital audio players from Apple Computer, Inc. Despite the light weight and compact size — most iPods are pocket size — the Hard Disk Drive can hold up to 10,000 songs* downloaded from a computer. Pioneer's CD-IU200V iPod adapter permits direct control and playback of iPod through our “iPod Adapter Ready” headunits. Connect the AVH-P4100DVD/AVHP4300DVD with an iPod via this dedicated adapter, and using the touch panel or soft keys, listeners can play iPod-recorded songs. (*When files in 128kbps AAC format are recorded in a 40GB Hard Disk).
