8.4" to 12.1" screen replacement

[AGillan]

So, I believeI I have everything I need . I purchased a new in the box 12 inch scree , with new module, the same cable infotainment uses, the one that has (DO NOT USE THIS PLUG) and cable 68417577AA LVDS , new bezel for my trim level( that was a pain in the butt to find correctly, the security gateway by pass by infotainment and the OBD2 module. I will have no problem with disassembly and reassembly , but I have apple computers so I know I have to use JSCAN to program the new unit. So all the parts are brand new that I got from a guy that purchased them from the dealer but traded the truck in prior to ever getting them installed. I even have all the receipts. All in so far at $1500. so I have never done anything like the programming that is talked about in this thread. so to say I am terrified that im going to cause a huge system problem due to me not knowing what im doing is an understatement. So does anyone have a step by step for dummies on what to do/ input with the JSCAN program. I have an 8.4 with nav, xm radio , heated seats and steering wheel and proximity sensors. No adaptive cruise or lane departure stuff. I searched but dee no thread on the JSCAN program for the swap. I don't want to have to purchase an android or PC just to program this on ALPHA OBD. Any help would be appreciated.
