I am in the same boat on the wife's 2015 journey R/T. A complete waste of time so far. Had it 2 weeks, booked the appointment at Chrysler dealer where they updated the radio and nav..still "can't unlock maps" they say call Garmin...Garmin says its a chrysler issue call Chrysler. So I call a different chrysler dealership and they say we just replace the unit with a refurbed one. They need to make an appointment to confirm the defected radio then order one....then go back to have it installed and cross their fingers it holds till the warranty is over...NICE!
I really hope I can do this myself and find the right files.
