Hey guys this is for Ram owners doing uconnect upgrades. If you do not already have nav in your truck (such as bighorn) it ia very hard to upgrade. I bought 12.1 display module and lvds cable. And still would not work. It has to be programed to truck with sales code by dealer. Dealships will not do it on a self install, nor will mopar sell u a module. Might be ok if you know a dealer.
