'Others' had problems because 'others' used incorrect part numbers (for the older lower bus speed CANBUS). I have researched the sheet out of this and now have the correct part numbers to do the factory uConnect install as long as I can get a Jeep dealer to update the VIN via the STARScan tool.
So yes, you can get uConnect working on an REQ 09 JK as long as you know what you are doing.
For my 09 JK the requirements are below (or at least this is what I am doing
)
Manufacturer Part #: 82211878
