That is I turned the ignition to position 1, got Sat Nav working and then removed the map DVD and inserted the CD. A message comes up to say that an incorrect DVD/CD has been inserted and to replace with an appropriate disk. This also came up with the v27.1 CD I had burned. In both cases I used Nero to burn the discs and used the option for burning a data disk. Can anyone help?
