I have a 2013 JKU with the 430n unit installed. I'd like to install a backup camera and use it while in motion. I'd also like to "unlock" the navigation input & video while in motion. Does anybody have advice/recommended parts I should be looking at. I'd like to keep this as a DIY project (although I’m not electrically savvy) to keep the costs to a minimum. Install tips would be appreciated as well. Thanks folks!
