I have a rvr and my screen on the mcs system is now blank. It first asked for the cd and then it went blank. I can see the cd turning but still nothing on the screen. The cd that I have is the navigation software version 8.1K I think that the cd is too scratched to work or I need a reboot cd or something. can you help me? I will pay if i need to get a new cd, I just want this thing to work.
