Axxess AXTC-LN29 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-LN29 Total Control Interface. Designed for select 2006 and newer GM vehicles, this vehicle-specific interface provides a complete solution for replacing the factory radio with an aftermarket receiver while maintaining important factory functions, including steering wheel controls, accessory power, warning chimes, balance and fade controls, and vehicle data communication.
The AXTC-LN29 combines Axxess Total Control technology with built-in steering wheel control integration, allowing users to retain factory steering wheel audio controls after installing an aftermarket radio. The interface supports dual assignment of steering wheel control buttons, giving installers the flexibility to customize button functions and create a more personalized user experience.
Featuring Auto-Detect technology, the AXTC-LN29 automatically identifies the vehicle type, radio connection, and preset control settings to simplify programming and installation. Compatible with major aftermarket radio brands, the interface also supports manual programming for additional customization when required.
Designed for non-amplified GM systems or applications where the factory amplifier is bypassed, the AXTC-LN29 provides 12-volt 10-amp accessory power and retains Retained Accessory Power (R.A.P.) after replacing the factory radio. 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-LN29 helps maintain a factory-style driving experience by retaining warning chimes through the onboard speaker, balance and fade controls, and steering wheel functionality. Its Micro-B USB update capability and nonvolatile memory allow programmed settings to remain stored even after battery disconnection or interface removal, making future updates and servicing easier.
Before purchasing, vehicle compatibility should always be verified. The AXTC-LN29 is designed for select GM applications from 2006 and newer, with compatibility depending on the specific vehicle 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-LN29 delivers reliable factory feature retention and professional aftermarket integration for a clean and seamless radio upgrade.
