Make your Garmin Montana 680t actually useful

Your knowledge about this unit is fantastic but I could not follow you with the computer screen work. I have this same unit and find it complicated to work with when you only use it once or twice a year.

Pode me instruir melhor em português a cerca da eficácia deste aparelho? Posso fazer demarcação com este aparelho?

Este gps sirve para hacer trabajo de topografía o cual me recomienda

[@foodieryder]

I have used it to do multi-day motorcycle trips. It needs the maps for routing.
