Axxess AXTC-LN31 GM Total Control Interface with Steering Wheel Control for Factory Radio Upgrades
Upgrade your GM factory radio system while retaining essential vehicle features with the Axxess AXTC-LN31 Total Control Interface. Designed for select 2017-2023 GMC and GM vehicles, this vehicle-specific data interface provides a complete solution for installing an aftermarket radio while maintaining important factory functions, including steering wheel controls, accessory power, warning chimes, backup camera retention, and vehicle data integration.
The AXTC-LN31 combines Axxess Total Control technology with built-in steering wheel control integration, allowing users to retain factory steering wheel audio controls after replacing the original radio. The interface supports dual assignment of steering wheel control buttons, giving installers the ability to customize button functions and create a more personalized user experience.
Featuring Auto-Detect technology, the AXTC-LN31 automatically identifies the vehicle type, radio connection, and preset control settings to help simplify programming and installation. The interface is compatible with major aftermarket radio brands and can also be manually programmed for additional customization when needed.
Designed for non-amplified GM systems or applications where the factory amplifier is being bypassed, the AXTC-LN31 provides 12-volt 10-amp accessory power and retains Retained Accessory Power (R.A.P.) after the factory radio is removed. It also provides navigation outputs, including parking brake, reverse, and speed sense signals, along with a 12-volt illumination output for compatible multimedia receivers.
The AXTC-LN31 helps preserve the factory driving experience by retaining factory warning chimes through the onboard speaker, backup camera operation when equipped, and balance and fade controls on supported systems. Its Micro-B USB update capability and nonvolatile memory allow programmed settings to remain stored even after battery disconnection or interface removal.
Before purchasing, vehicle compatibility should always be verified. The AXTC-LN31 is designed for select GM applications from 2017-2023, including certain Chevrolet and GMC vehicles, depending on the model, factory equipment, and audio system configuration.
Whether replacing a factory stereo, installing a touchscreen receiver, or upgrading a GM multimedia system, the Axxess AXTC-LN31 delivers factory feature retention and professional aftermarket integration for a clean, reliable radio upgrade.
