If you have a 2011-2012 vehicle with the RES radio that has no Uconnect buttons, there is now a MOPAR kit available. They have had it for a few weeks now. The kits consists of:
the module, wire harness, external mic, a small UCI touch pad that has the Uconnect buttons and instruction disc. (Approximate cost $349)
After the installation of the kit, you'll need to have the vehicle flashed to code "RSP". The kit is an easy installation and flashing needs to be done by the dealer. They'll try to charge you for an hr labor; it takes less than 1/2 hr so tell them that you're willing to pay $50.
You will also want to purchase the iPod / USB cable (about $35) PN 82212160, this will be needed for any Uconnect SW updates as well as iPod/ USB media playing.
the kit PN's:
Low Speed CAN BUS vehicles --82213219
High Speed CAN BUS vehicles –82213221
I have also just found out that this kit will work on any year RES radio without the Uconnect buttons on the radio. This appears to go back to 2009 vehicles. I have placed the installation guide at the link below.
