This is a new (old stock) Peripheral (now PAC audio) PXDP3 iPod and auxiliary audio input adapter for select GM vehicles. It includes an iPod connection cable. A vehicle-specific adapter harnesses is required (PXH3GM, for example) to integrate this into factory radio. This version of PXDP3 may control, but not charge, some of the newer iPods and iPhones that require 5V for charging. There are adapters available to connect to the end of the iPod cable to enable charging of these, however, or a newer version of the PAC audio iPod connection cable can be ordered (or an Aux input cable could be ordered and fitted) Compatible vehicles include: Peripheral is now PAC Audio. The PXDP3 allows you to add a stereo audio input through your compatible factory radio (via an unused CD changer, satellite radio, or other port) that can then be used to play an iPod or other music source into your radio cleanly, and without static of an FM transmitter. Installation in W and NW Chicagoland is also available, if needed, for an extra charge. I have a mobile electronics installation business and am selling off some excess inventory. Please feel free to send a message if you have further questions about any of my items, or a question about your specific mobile electronics needs.
