Review on PAC RP4 CH11 Replacement Steering Interface by Bob Schultz

so I decided to fit this new radio on my 2015 Jeep Patriot Crutchfield said I need this module I am sure the module comes with instructions easy to read and understand and when you do the wiring MAKE SURE WHAT YOU KNOW IF YOUR CAR HAS A FACTORY AMPLIFIER ANYWHERE OR NO I made the mistake of thinking I had a boston speaker system and literally had to redo the speaker wiring, just to adjust all colors. but this thing requires no programming if you set the dial to the correct brand of head unit that you install BEFORE PLUGING IT INTO YOUR VEHICLE.
