I currently have a 2021 JL Rubicon and want to do a total upgrade to the 8.4 and LTE system. I know that there many threads about different parts of this topic, but I have not found one that totally covers what I am looking for. When I bought my JL, my options were limited and I got a great deal so I could not complain. I have slowly been adding on all of the features that I wanted to buy it with after the fact (and for the most part significantly cheaper, IE the stock steel bumpers). That being said, I am trying to form a total parts list to accomplish this. I currently have the Uconnect 7. Has anyone had any success in upgrading not just the size, but also adding the LTE? I know there are other options for adding wifi, but I want to go in this direction. My first concern is that I am finding two different part numbers for the 8.4 68429173AB and 68295725AH. I believe the first is for the newer JL's and the latter is for the older ones. Am I correct? I just want to make sure before I spend $1425 on a radio. I believe 6AB55TX7AB is the number for the bezel and 68293962AA is the part for the LTE antenna, but I can not find a part number for the burgundy fakra cable. I also can't find a part number for the rear view mirror. What other parts am I needing and does anyone know the missing part numbers?
