2002 Jeep Grand Cherokee
Crutchfield Customer Review (What's this?)
Installation was easy enough, programming was simple. They include way more wire length than most will probably need. It works great. My wife loves that she was able to retain her factory steering wheel controls.
Pros: It does what it is supposed to do without any hiccups. Included references are all you will need to get it working.
Cons: It felt a bit lighter than I anticipated, but I suppose it is just a tiny pcb in a black plastic box.
