I just purchased a 2005 f250 lariat. I was surprised that it only has the mini message center and not the one with mpg, miles to empty, temp etc. I would have thought that would be standard on a lariat. Anyway, is there a way to easily upgrade this? Being a lariat would the harness already be compatible or would it require the same steps as the xlt, adding pins and wires and such? It would be nice if it was just plug and play.
