I am using two different maps on my Garmin GPSMAP 64s, the Garmin GB Discoverer 1:50k map and the Talktoaster (OSM data based) map. As I am sure everyone knows, the Discoverer map looks rubbish when zoomed in beyond about 200m. I noticed that when I zoom all the way in to 5m, the Discoverer map disappears and the Talkytoaster map is visible. What I want to do is change this so that the Talktoaster map layer takes over at any zoom closer than 200m.
I can't see a way to do this within the unit itself so presume I need to edit the map. Using GMaptool I see levels and zooms listed in the Discoverer map and I presume these are somehow important. My initial research suggests that I need to see if I can change the draw priority at a specific zoom level, is this possible? As I understand it, the maps are displayed as layers on the device, and the draw priority controls which is actually displayed. My thinking at the moment is that I somehow need to make the maps either only display at certain zoom levels or change the draw priority at specific zoom levels. This however is as far as I have got and, rather than reinvent the wheel, I thought best to come here and see if anyone else has solved the problem.
My other idea to potentially get this to work, based on noticing that the Discoverer map disappears at the highest magnification, is it possible to stop that map being zoomed in that much, making the Talktoaster map default to the front once I zoom closer than the 200m setting? Or conversely, remove the extra data from the talkytoaster map so that it is only visible after 200m, but has a higher draw priority than the Discoverer map?
