I am considering purchasing JLU Rubicon when the full color choices become available. I am trying to determine the last few upgrades. Has anyone had any experience with the 7" and 8.4" Uconnect? I am leaning towards the 7" as I will be using Android Auto for Navigation and would prefer the extra room instead of the subwoofer. Does the 8.4" screen offer anything more that I am missing? Is it a better quality screen?
