Axxess AXTC-A12 is a vehicle-specific Total Control radio replacement data interface with built-in steering wheel control retention for select 2002-2013 Audi vehicles. It is used when replacing the factory radio with an aftermarket radio while retaining supported vehicle functions that may otherwise be lost.

At a Glance

  • Built-in steering wheel control retention with Axxess auto-detect technology
  • Provides accessory power where supported by the vehicle application
  • Provides NAV outputs for parking brake, reverse, and speed sense
  • Allows dual assignment of steering wheel control buttons
  • Designed to work with major aftermarket radio brands
  • Micro-B USB updatable for supported firmware updates
  • Designed for non-amplified systems
  • Retains balance and fade
  • Provides 12-volt illumination output

System / Wiring Notes

  • Factory feature retention depends on vehicle trim, factory radio, factory amplifier, and original equipment
  • Retained steering wheel controls require proper radio-brand selection and interface programming when applicable
  • Additional dash kit, antenna adapter, camera adapter, USB adapter, or amplifier integration parts may be required for a complete radio installation
  • Verify exact vehicle year, model, trim, factory audio package, and system/RPO codes before purchase
  • Verify radio type, navigation status, and Bose/non-Bose audio system before purchase.
