Navman ISDN 3000 map not available?
My Navman ISDN 3000 displays a message 'MAP DATA NOT AVAILABLE'. The screen link for 'route information' is faded.
All connections are in place and unit has been working until now.
The manual says that one can scroll through the maps listed on the memory cards but altough they are displayed it is not possible to scroll.
