Question about Teasi ONE³ Extend
can you also use topo switzerland v.4?
Topo V.4 is a Garmin map. It does not work on a TEASI. However, the trail coverage (even small trails) is really good in the standard map from TEASI (based on OSM). If that's not enough, you can use raster maps from MagicMaps or Kompass. But you don't really need them.
The Teasi is based on a different mapping system and I can't imagine that topo switzerland v.4 can be loaded onto the device. I don't see how?
