I have a 2019 Ram Longhorn ,I am on my 3rd Radio 8.4. I had problems with Uconnect, Gps, and Radio. also back up camera display would go blank at times. Uconnect would tell me it is a Ram Problem and not theirs. Salesman said problem was my I-phone working with uconnect! Well on my 3rd Radio at least my GPS actually works better than before, but radio is still having problems.
