ControlPRO is a free Android app that works with ControlPRO Steering Wheel Control interfaces from Pacific Accessory Corporation (PAC). The main purpose of the app is to provide the ability to custom configure the vehicle's original steering wheel controls to operate the functions of the aftermarket radio.

The app is easy to use and offers a range of customization options for the steering wheel controls. Once connected to the ControlPRO SWC interface, the app allows users to assign different commands to different buttons on the steering wheel. This means that users can fully customize the way they interact with their car radio, making it more convenient and intuitive to use.
