I think you should be ok going right to 18.x. your, albeit old [emoji16], sw version is on the list in the chart so I think you'll be fine.Chris....if I remember correctly you too have a transplanted RA4 in your Ram? I have a 2017 Ram 2500 that had an RA3 from the factory. I installed an RA4 into it. The RA4 I obtained came out of a 2017 Ram (part# 68270661AF). It currenly has SW version 16.51.19.
My question is: DO I NEED TO UPDATE TO SW 17.43 FIRST BEFORE UPDATING TO 18.45?
I read MGrimm's post #3 on the first page and if I understand the post (and the chart in it) correctly, I do NOT need to update to 17.43 first. But I am not 100% sure since there is so much info contained in the several threads on the forum and I am looking for guidance. You and Grimm seam to be the ACE'S on this. Any input of course is welcomed!
Someone here already even updated to 18.45.01 from a version NOT in the chart and it worked fine there too.
