3/3/2004
The 2004 Innovations Award winner, the Peripheral Electronics PXGM24 is the industry’s first stand alone auxiliary input for GM Class2 vehicles. The PXGM24 interface will allow up to two auxiliary input sources to play through OEM radios that are equipped with the GM 24 pin harness. The PXGM24 was created to provide a fool-proof method for supplying a direct audio input for multimedia installations. This plug-n-play solution surpasses FM modulation which is the current method of introducing audio in these systems. Selecting an input source is as simple as pressing the source button on the radio. The head-unit can toggle between all the possible sources as if they were factory installed, displaying CD, FM, AUX1, AUX2 or whatever source is selected. Some of the vehicle applications include 2003-2004 Full Size Pickups and SUV’s, Trailblazer, Monte Carlo and Impala just to name a few. The PXGM24 also has four independent level adjustments for each input channel. Adding a multimedia system or XM radio without degradation of sound quality is now a plug and play interface away.
