Review on 🎵 PAC RP4-GM31: Premium Radiopro4 Stereo Replacement Interface with Steering Wheel Controls, Canbus Enabled for Select GM Vehicles by Ryan Fuhrer

This kit was purchased for our 2011 Chevy Impala no Bose system to install an aftermarket stereo system. The instructions are a bit confusing as the diagrams show 3 connectors and only 2 connectors are included in the kit. Two is all you need. If you know the basics of radio installation, you shouldn't have any trouble. The interface retains standard steering wheel controls and also retains doorbells and accessory power after the key is removed. When installing, you teach the interface the keys you have and it remembers them. This learning process was very easy and the interface works absolutely perfectly. I was worried about spending a hundred dollars on a kit that I would have to solder/crimp. My fears were unfounded as this kit works great. This allows you to use the steering wheel control with most newer stereo systems that have a steering wheel control feature in the harness or connector. I highly recommend this interface if you are considering a factory upgrade. Radio, steering wheel controls and factory functions work perfectly.
