Came with NAV from factory, so I'm guessing RA4.
If thats the case, you can get 17.43.01 here: https://www.ramforum.com/threads/info-2013-2018-8-4an-fw-notes-ra4-vp4-na-uax.73871/ and follow the posts/instructions to get it installed. Be sure to get the correct one for your model year, they were model year specific back then.
Once that is done, go here to get 18.45.01: https://www.ramforum.com/threads/ro...sw-update-13-17-ra3-vp3-na-ra4-vp4-na.150150/ This update is not model year specific, so you just need the correct one based on your radio type (assuming you have RA4, just grab the RA4 version)
It might not hurt to try 18.45.01 first, I have heard of people successfully going from 16.x to 18.45.01. I dont think there is any harm, it looks like the installer just wont start the update if it doesnt think you can get to 18.45.01 from your original verison.
