The kit integrates two auxiliary audio sources directly to the factory radio for the highest possible sound quality—ideal for mp3 players, portable DVD players, handheld GPS, laptops, and gaming systems.

  • The plug-and-play installation maintains factory wiring integrity.
  • Direct audio input to factory radio for maximum sound quality
  • Two separate inputs - RCA and 3.5mm minijack
  • Retains factory-installed satellite radio
Compatibility Notes:
  • The vehicle MUST be either equipped with or have the ability to support Satellite Radio
  • Radio must have a "Band" or "XM" button to be compatible

Vehicle Specific Notes

  • 2009 Pontiac G6 - GM changed the radio halfway through the year, so there are two harness possibilities in this vehicle. If the vehicle's radio looks like the first picture, you are good to use the ISGM533. However, if the vehicle's radio looks like the second picture, you will need to use the ISGM532.
