Extension Harness AX-Series Interface - Fits GM 2016-2021

YIf your GM vehicle needs an AXGM-Series radio replacement interface, an extension harness might also be necessary, depending on the vehicle setup. Many GM models locate the factory tuner remotely, such as in the rear of the vehicle or behind the passenger-side kick panel, which requires extra harness length for proper installation. The AXEXH-GM10 extension harness offers the additional reach needed to connect your AXGM-Series interface at the radio location to the factory tuner.
