Axxess AXRSCH-GM31 Radio Status Control Harness for Select GM Vehicles

Axxess AXRSCH-GM31 is a vehicle-specific radio status control harness for select 2019-2024 Chevrolet and GMC vehicles. It pairs with the Axxess AXRSC interface to help retain supported factory vehicle information, steering wheel controls, accessory power, and status-control functions when replacing the factory radio.

Exact Vehicle Compatibility

Find your vehicle below, then match the model year and factory-equipment details in the same row. Factory radio, amplifier, navigation, trim, speaker location, and connector differences can change which installation parts are required. If anything differs, contact MCOR before ordering.

Fitment note: Year and model alone are not always enough to confirm compatibility. Match every factory-equipment qualifier shown for your vehicle, and contact MCOR Automotive if the radio, amplifier, navigation, speaker, camera, trim, or connector details are uncertain.

Installation Notes

• Confirm exact vehicle, radio, and factory system compatibility before installation
• Read the current Axxess or Metra instructions before wiring or programming the interface
• Additional dash kit, antenna adapter, camera adapter, amplifier interface, or radio-specific harness may be required for a complete installation
• Professional installation is recommended for proper integration and retained-feature operation
