I have a eTrex Vista HCx and a microSD card. I am trying to load both Canada Topographic maps and BlueChart maps for my area. I can do each separately but when I try to put them all together I only see the BlueChart maps.
So far my only option seems to go to the menu and select/unselect all 180 Topo maps or all 165 BlueChart maps.
Is there an either way to switch back and forth on the same card such as a single menu function?
Thanks
