I have a Garmin 680 that i had no issues for years until i had to insert a 4G sd card because the new maps wont fit in the original place.
It loads the maps fine.
My last route planing was from Kitchener,On to Knoxville,Tn A distance about 700 miles.
Before i had no problem with the route calculations even when i planned a route all the way to California.
After the map upgrade it could not calculate the route, it starts to calculate and then after awhile it stops and displays =not enough memory.
I cant find anything after a few hours of search .
Any advice would be appreciated .
