Axxess AXTC-LN44 Data Interface with SWC for Select GM Vehicles

Axxess AXTC-LN44 is a vehicle-specific Total Control data interface with built-in steering wheel control retention for select 2008-2016 GM vehicles. It is used when replacing the factory radio with an aftermarket radio while retaining supported vehicle functions that may otherwise be lost.

System / Wiring Notes

• Additional dash kit, antenna adapter, camera adapter, USB adapter, or amplifier integration parts may be required for a complete radio installation

• Designed for non-amplified models or installations bypassing the factory amplifier. Verify NAV and climate-control notes before purchase.

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 compatibility and factory audio system before installation
• Read the current Axxess instructions before wiring or programming the interface
• Professional installation is recommended for proper radio integration, steering wheel control setup, and retained-feature operation
