I took delivery of my 2017 Challenger R/T Plus on June 27, 2017. Later that evening when I tried the navigation system all I got was a new screen showing a picture of a blue globe with the land masses in yellow. To the left of the globe it said NAVIGATION LOADING with a series of dots going back and forth. My car is still not fixed after two trips to the dealer and numerous calls and emails to the UCONNECT group and Dodge Customer Assistance. One group tells me it needs a new software upgrade which was to be released in mid July or early August. The Service and Parts Director at the dealer told me he was ordering a new head unit for me on July 18, 2017. So far I have not heard from him. This vehicle is the first Chrysler product I have had. My confidence in this car has been deeply tarnished. It appears that Dodge really does not care about my issue. Is there anyone else out there that has had problems with their 2017 UCONNECT ? Mine was factory installed and is a 8.4NAV/UAQ unit. Everything else on the system seems to work fine. I am very interested in hearing from others that have had UCONNECT issues and how they were able to get the problem resolved. Thank You.
