What’s the advantage to this over google maps

10

It is entirely offline once set up. No other benefit.

11

You downloaded the torrent file, which is just a link to the actual download. They have a non-torrent download option.

12

I don’t see anything

13

To enable direct downloads, you have to make a donation first. I’m trying to upload the USA map to my google drive so everyone can download it for free. It’s 5 GB, so it will take a while to upload.

Its hidden. Try typing in ProgramData in the address bar of file explorer

Yeah I know that
But in the Garmin dir I don’t have a dir called maps

Did you run Basecamp yet? I think that the Maps folder might be created the first time it runs.

Yes I did
