Review on 🔌 PAC RP5-GM11 Interface: OnStar Retention, Steering Wheel Control, Navigation Outputs for Select GM Class II Vehicles by Ron Collins

All connections soldered and heat shrunk, installed and tested before zipping up the dash. I go out the next day and none of the SWCs are open. It's still beeping, reverse horn, remaining power etc so I know the box is still alive. About once a day my head unit (Jensen CAR10) goes haywire like someone is randomly pressing all the buttons on the steering wheel. When that happens there is nothing I can do about it, incredibly annoying. It will take hours to take the dash apart and see if I can figure out what the problem is with this box/replace it. I wanted to update the firmware but no, I'm not going to pay PAC any more money just to update their crappy box.
