My sister-in-law just purchased the e Trex Vista H and wants me to upload the Europe NT maps on it. We plan on buying the DVD that the Garmin site says is compatible with it. I have a few questions.
1) The e Trex doesn't have any SD card input, only USB and only has a 24MB memory. Will I be able to have the US maps (preloaded) and the Europe maps fit? If I delete the US maps, will we ever be able to get them back?
2) I have a PC and she has a Mac. If I install the maps for her on my machine using the "one-time-code", will she ever be able to use it on her computer? What if it needs to be reloaded?
