The AXTC-A12 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 driving experience.

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-A12 helps maintain a factory-style experience by retaining balance and fade controls while providing reliable communication between the vehicle and aftermarket receiver. 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-A12 is designed for select Audi applications from 2002-2013, with compatibility depending on the specific vehicle model, factory equipment, and audio system configuration.
