Don't know what the latest version is but my 2019 with the 12 inch has had a non working navigation system since last November. Many calls to the dealer who keep stating don't bring it in we don't have a fix yet. Many calls to Ram Cares and Uconnect and nothing but a run-around and finger pointing. They finally started to advise in early February 2021 that there would be three updates to fix many of our issues. The first two updates would be over the air starting in April. The third and final update must be done by the dealer after the first two over the air updates are completed. I haven't received the first over the air update and calls to Uconnect to advise the person I was dealing with about this and she said she would look into the issue and get back to me. She did not. Calls left on her voicemail have not been returned. I have countless phone calls, promises, appointments broken by the dealer, lies, and I'm still sitting here six months later with a non working Navigation system that I paid for and is under supposed warranty and hasn't been fixed. Pissed doesn't even begin to address my feelings toward Ram. I should have had a new radio or whatever it takes put in a long time ago, whatever it takes to honor the warranty.
