Updated post 5 with the 2016 RA4 v16.33.29 fw link, TSB Change notes, and update directions.
Note: Took a look online at a few 2017 Rams with RA4's and they appear to be the same radios/architecture. Looks like people will be able to convert ra1/ra2 radios to the 8.4's for another year.
Here's the TSB 08-57-16 Rev A notes:
I successfully updated my 16 8.4n to this software. Thanks for the help!
