After 5+ years of faultless service, my Zumo660 has recently decided not to display roadmaps and literally has no idea how to plot a route to a selected destination anymore. In addition, I normally plan routes on BaseCamp and then load the route onto the 660, which it ignores and just shows me a blank display (see pic). However maps display perfectly if I don't select 'where to' or tell it which route to follow. The unit has Basemap NR 5.01 & I have Garmap NT 2012.3 on the computer.
Perhaps it does not like the fact that I dont use it on a bike anymore.
Any ideas?
