iSimple ISGM535 – AUX Input Interface for 2006–2013 GM Factory Radios

The iSimple ISGM535 adds a clean and reliable 3.5mm AUX input to your GM factory radio.
It works with many 2006–2013 Chevrolet, GMC, Buick, and Cadillac vehicles that use the GM LAN (GMLAN) radio system.
You can connect phones, MP3 players, and digital music devices directly to your OEM stereo without replacing the head unit.

Because the ISGM535 plugs into the factory harness, installation is fast and simple.
There is no cutting, no splicing, and no programming required.
As a result, you keep the original look and sound of your dashboard while gaining modern audio capability.

Why the iSimple ISGM535 Is a Great Upgrade

This interface delivers clear sound because it sends audio directly into the factory radio.
Additionally, it maintains all factory functions such as steering-wheel controls and radio display.

Therefore, you get clean and dependable audio through your original speakers.
