Re: 2011 Jeep Grand Cherokee MGIG RER Install
The RER needs to have an AE engineering change on the part number. I forgot to add you need to replace the mic cable. As soon as you install it starts working but you have to get the CPU reflashed. I didn't right away and there's some conflicts going on such as the alarm going off a few minutes after locking with the push button on the key plus when you express up on the windows, they expressed back down. It only happened twice so it's not like a huge deal. Also, the instructions in the box for the mic cable are for a '05-10.
