Am I able to create my own POI's within MM, or do I have to import POI's exclusively from external sources?
No problem observing a track in MM but when I am stationary, the fix wanders erratically until I resume forward movement. My solution is to disable GPS from within MM while static in order to stop my screen becoming one large Etch-a-Sketch doodle.
If I know generally where I will be travelling, it is not difficult to download map data along the route prior to departure, given a WiFi connection. I usually prefer to use google maps. Here's the thing...I repeatedly am unable to download maps beyond a certain zoom level, usually no closer than level 2 or 3.
