In anticipation of my 5X arriving (fingers crossed), I've been playing around with Garmin BaseCamp to prepare routable topo maps (from OSM-derived sources) for a planned April hike in Patagonian Chile. My question is about elevation data / contour lines.
It seems like many of the handheld Garmin GPS units support loading and layering multiple maps, such that you can have satellite imagery, routable road/trail maps, and a "map" of just elevation contour lines, and then turn each of them on/off independently on the device (depending on what you want to see). This seems pretty ideal: I'd probably just look at the trail most of the time, but it would be nice to have the contour data still available, for example, to show the elevation profile mid-route.
Does anyone know if the 5X will support this feature? Did the Garmin Epix? (Without direct user reports, I'm prepared to assume that the 5X starts with the same map/nav featureset as the Epix watches).
I ask because if the 5X can only work with a single map layer, I'm under the impression that I need to "merge" OSM topo maps with contour files in order to create a single blended map. That seems to require playing around with some open source apps and scripts... or paying the (relatively cheap) openMTBmaps subscription to get it done automatically.
Advice?
