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

Used for 2012 GMC Sierra with premium BOSE system. Apparently there are at least two different Bose systems. There may be a third Bose system, but either way this interface works on all the different Bose systems. I tried the proprietary Scosche interface on a truck of the same year and model, but it didn't work with this particular Bose system. The steering wheel controls are already integrated and programmed, so all you have to do is connect the cables to whatever new radio you're using and you're good to go. Worked great.
