Radio Status Control Harness for GM 2019-2024

The Axxess AXRSCH-GM31 is a vehicle-specific radio status control harness designed to facilitate seamless aftermarket stereo installation in select 2019–2024 Chevrolet and GMC vehicles with non-amplified factory sound systems.

When replacing the original factory head unit in these modern GM trucks and cars, critical communication links are broken because the factory screen functions as the control hub for the vehicle’s data networks. This harness acts as an advanced data bridge. It interfaces directly with the vehicle's electrical system to extract, retain, and display essential safety alerts, driver configuration sub-menus, and climate status monitors directly on the screen of your new aftermarket stereo.

  • Allows the retention and adjustment of the OE personalization settings
  • Retains audio controls on the steering wheel
  • Works in both single and dual-zone vehicles
  • Retains safety chimes through an included off-board speaker
  • Plug and play installation, no cutting or splicing required
  • All features retained are dependent on the vehicle application
  • Authorized Internet Dealer
