AND / OR sd card in /map
Well, all has been fine, no problems at all. Sudenly, the otherday I noticed all the roads on my route had disappeared. The PLANNED route was there but if I hit "view map", the screen is essentially blank...
If I zoom out I can see my favourites but once again, no roads...
WTF???
So, after resetting the device, I tried again, re-installed the maps but as yet have had absolutely no luck.
As a last resort I tried garmin express to reinstall my original 2012 map. That worked... Deleted those files and replaced with 2015.20. Tried unlocked img, tried locked and used jetmouse to create unl file..
I've been doing this for years, what the hell has happened??
Any input gratefully received...
