Offline Maps vs Waypoint & Track Navigation
Knowing your position is not the same as having a full map. Outdoor devices can support very different combinations of maps, routes, tracks and waypoints.
Planning guidance — final supplied configuration remains project-specific.
Tracks and waypoints can work with less map detail
A route line, breadcrumb trail, return path or saved waypoint can still be useful when a device does not offer full map detail. The exact workflow varies by model.
Plan for loss of phone coverage
Confirm which functions remain available when the paired phone or mobile network is unavailable and what route information must be loaded before departure.
