Review on PAC RP4 CH11 Replacement Steering Interface by John Caldwell

I have a 2011 Jeep Liberty Limited Edition. I installed Alpine ILX-W650. This allowed me to keep the controls on the steering wheel and saved myself the hassle of connecting stock wiring harnesses. Gives you a description of what each wire does and all I had to do was match it to my new head unit's schematic. I haven't tried reprogramming the buttons, but the fact that you can is so cool.
