Hi there i have been using 2005 Tele Atlas DX discs with no problem. I recently updated to 2007/08 discs which are also DX, however they have iTMC included.

They display an error saying ' please insert a Travel Pilot DX disc'.

Is there an update i need to do for iTMC to work. Do i need discs without TMC, or is it nothing to do with this?
