iSimple ISGM531 – Dual Auxiliary Audio Input Interface (2007–2012 GM Vehicles)

Add modern audio flexibility to your factory stereo with the iSimple ISGM531 Dual Auxiliary Audio Input Interface. This plug-and-play module integrates two auxiliary inputs directly into your OEM radio, giving you CD-quality sound from portable devices without changing your factory system.

With both a 3.5mm stereo jack and RCA inputs, the ISGM531 works with MP3 players, smartphones, tablets, or satellite radio tuners. Installation is simple, since the adapter connects to the back of the factory radio and retains the integrity of your original wiring. Even better, it keeps your factory-installed satellite radio fully functional.
