RHB Navigation Update

The disc reader went out on the second REZ that I put in my 09 Routan. I found a great deal on an RHB out of a 2012 Grand Caravan and have it installed and running great.

However, I would really like to get the NAV maps up to date. According to Garmin, there should be able to go to an "Update Maps" option where I would be able to update the maps using their Garmin Express software and a Thumbdrive. However they say the RHB needs to have NAV software version 5.13 or higher and I can't find out how to get mine to that level.

I went to mygig-disk, downloaded the 2 updates that they have, and my radio is now at a software version 50.01.01 but my NAV software still has GPS: 2.90, Text: 3.00, and Audio: 2.30

I have looked around and there is some pretty good information on Jeep sites with regards to the map updates on this radio but I can't seem to find information on updating the NAV software.

Does anyone know how to go about getting my NAV software updated to 5.13 or better?

Hopefully something in this post can help. If it wasn't for the RES, I would have replaced it with a modern HU.
