DESC: This unit not only plays burned DVD's and Karaoke CD/DVD's, but it can also play MP3 and MPEG-4 formats which make it ideal for the technologically savvy consumer or anyone who wants the freedom to play almost anything on their system. The backup camera input makes hooking up a camera both easy and convenient. The USB and SD Card inputs allow you to play MP3's right off your phone or flash drive - it's that easy! ZpodLink provides iPod and iPod Video playback through your vehicle sound system via a direct connection between the iPod and In-Dash unit.
