Any of your guys that have change over to a RER mygig from a REN w/uconnect,
Did any of you use the jumper wiring harness 82211666, if so did you have to completely unhook the uconnect module that is separate from the radio? since the RER has it built in?

 

I believe so. and you have to add a microphone or if you have the mic in the mirror already you should just need the jumper. I am not totally sure but there are tons of sites
