If i put a memory card containing ,garmin topo great britain pro 1:50k into my etrex touch 35 . Will i need to enable any other maps or will just that one do. Thanks

The touch 35 won't need any other maps, using the topo as the only map is fine, there are some transparent maps which are used to ' lay on top' of existing maps like contour only maps for example, but the topo should not be one of those
