Hope this helps someone as I struggled over it a long time. I had a RER Navigation unit from a 2009 JK (the older version) and bought a 2011 JK. My issue was whether the unit would work in the 2011's. Some said yes, some said no. My 2011 came stock with the basic stereo plus Sirius and the mysterious "connectivity" package. My hope was simple plug and play - well almost. Everything was exact fit and working minus the mic connection. Seems the mic goes through this bluetooth/Uconnect module and won't work.
Simply use your old mic from the RER or order the Mopar one and you're set. You'll have to manually mount the mic and the GPS antenna but there's a place for the antenna above the instrument cluster! I used nylon ties through the holes to hold the GPS antenna and double sided tape for the mic. Also, the steering wheel controls worked perfectly and my phone paired.
I had hoped to use the factory pillar mic but as I said, it must go through the bluetooth/Uconnect module. I wish I could find the module and disconnect it. Then find where the mic plugs in but I don't feel like removing a bunch of console and dash parts.
If anyone else has been through this, please share your experience with myself and the others.
