Brother went to Dealer twice because NAV not working right. They just said it needed update of uconnect system.Still doesn't work.
When my wife wanted new maps in our 2017 I did the sys. update and bought the 2021 map from HERE.
Checked my brothers 2016 uconnect sys. version and it was the original. Dealer doesn't know what they are doing.
But, then operating systems and firmware really don't fall under the category of Auto repair, or maybe the Dealer needs to hire a programmer full time!
P.S. Install your update on another USB, and keep trying until it takes. A guy on another Jeep Forum said his was acting like yours, but he did it while driving to work and it took?
P.S.2 The update is really slow. It will take 20 to 30 minutes. Watch it carefully, and don't get
impatient. Do it with the motor running.
The map update takes well over an hour. I had to open the hood and use a fan when I did the map
update..........
