This Maestro ADS-MRR radio replacement and steering wheel interface allows you to control an aftermarket radio from the steering wheel of your compatible vehicle with programmable buttons that you can assign functions to from the Internet.

This AXXESS add-on amplifier interface is designed for use when replacing the factory radio, such as with Metra’s dash kits. This retention interface will retain the Bose amplifier and the balance audio feature when replacing the factory radio in select 2014-2021 GM vehicles, and is micro USB updatable.
