@Johnt999 Without connected services I am unable to receive over the air updates to the infotainment system. I still lose all my radio presets every couple weeks. Dealer was going to update it when it was in for a recall but they said the guy that does it was really backed up. Also, with my 2020 I was able to use the app for remote lock, start and navigation. None of the remote services with the app work. I did a pm (private message) with RamCare w my VIN to see if connected services could be added. Was told no way to add it.
But after all of this I am satisfied with my 3500, mechanically it is sound. I purchased it for towing my fifth wheel and I love the extra payload and the air suspension. And I am still very impressed with the Cummins, on my 3500 and the 2500.
