New Axxess® Total Control SWC Retention and Data Interfaces for GM and BMW Now Shipping

Jul 16, 2020

Holly Hill, FL –  July 16, 2020 – Axxess® by Metra Electronics®  is now shipping new integration products for a wide range of GM and BMW vehicles. Adding to the Axxess Total Control Interface Series™ (AXTC) are eight new solutions for radio replacement integration, which include vehicle-specific harnessing and the AXTC data interface. When replacing a radio, the interface utilizes patented Auto-Detect® technology1 that automatically detects the vehicle type, radio connection and preset controls, while allowing the ability to dual assign steering wheel controls. The AXTC interface also provides additional patent-pending features to give installers a single solution that offers total control. It also provides NAV outputs, accessory power and a 12-volt illumination output, in addition to retaining R.A.P. (retained accessory power). Additional features vary by vehicle application and may include chime retention, retaining balance and fade, and more.

The Total Control Interface Series is designed to work with all major radio brands. In addition to Auto-Detect, it can be manually programmed for most vehicles and will retain most settings even after battery disconnection or interface removal. Axxess has upgraded the LED feedback for simple, easier programming experience and provided improved, user-friendly instructions and a smaller interface box with a low-profile footprint. The entire series can be seen online at
