Hi people,
I lost my original post somewhere in this forum - my apologies if it shows up somewhere it shouldn't
My problem: I loaded 3 sets of maps onto a micro SD (Bluecharts, Tides and Shonky Topo). When I viewed them in the unit, they all seem to be overlayed?
I cannot disable each individual set? I tried loading the same via USB cable and the same result.
Is there a way to load these and be able to enable/disable them on the unit?

Cheers
