On the Oregon 600 and 62s the switch between 50k and 25k is made automatically at a certain zoom level (based on map-detail) with the same draw priority (20) for all maps.

Makes sense, doesn't work on the Oregon 550T either. But in both the 300 and 550T the 1:50k is listed higher up in the list of maps.

Ok, just changed parks+trails to priority 21 with Gmaptool, all looking good!

But only worked by deleting maps from card and re-copying them with the changed priority, when I used Gmaptool directly on the files, on the card, no difference, even though Gmaptool showed priority has changed,don't know what was going on there.

Thanks everyone.
