So here's the story. Sent my unit in for the the ribbon repair(not pioneer) got it back and installed it today. When I put in the east coast disc I get "incorrect disc please insert appropriate disc" So all I can figure is I loaded the 50mt disc about a year ago(to upgrade) but that wasn't the one the unit came with. I don't have the original discs (were they the 40mt?) So what should I do now. Everything else works,ipod,dvd,sirius,xm just cant use the nav
