There are 3 different suppliers for the uconnect system. This particular update is not for the 2013 Uconnect system in your truck.
Unfortunately, it doesn't appear that Dodge get a very good job at Validating this system before releasing it to be built into the vehicles.

I was wondering if anyone could help me with getting the update downloaded? Any help would be greatly appreciated!
