It can be done,
infotainment has a complete kit and makes it easy but you can absolutely piece it together for cheaper. Good luck finding any used screens.
At a minimum: you need the screen, control module, a couple harnesses, bezel, center stack, auto climate sensor if you want that, alfaobd and bypass harness. I'm sure there's more stuff, there are others here that have done the swap on 1500's and it is largely the same. You won't need the xm or nav antenna to add those functions, just the module and cable.
