Does it work outside of cellular network?

GPS track recording works anywhere on Earth (e.g. mountain, sea), without network (4G, Wi-Fi).

[Without network, initial GPS fix may take several minutes. ]

OpenStreetMap and its variants work without network with Offline Map Cache. Other on-line maps require network.

Does it support Offline Map Cache?

Yes, offline map cache is supported for OpenStreetMap and its variants.
You can use GPS-Trk with offline map, even in foreign country (without roaming) or outside of cell network (sea, mountain etc.) anywhere on Earth.

  1. Go to Map screen and press Menu button.
  2. Select 'OSM' or its variants. Press 'OK'.
  3. Scroll and zoom the map so that the desired map area is displayed.
  4. Press Menu button and press 'Cache' button.
