Had my '17 XT5 in for maintenance last week. They gave me another XT5 to run around in that had 3rd zone climate control which I knew about but was the the first time I've seen. Thought the feature was very nice.
Does anyone know if it's possible to retrofit from a salvage this feature? Is the system quite a bit more than just the control module on the back of the console? Possible the wiring is already in place?
I know a long shot but thought I would ask?
