You don't download directly to your etrex. These are the basic steps:
Download the map file
Install maps into either BaseCamp or MapSource
Use either BC or MS to install maps to your etrex
That depends. If you download an img file there is no need to use either BC or MS, you can load it directly onto the GPS.
Indeed, but I've never seen a downloadable img file, have you?
Yes, often. I would not have posted the info had I not done so myself.
Agreed, many sites provide .img files that can be simply 'dropped' into your GPS.
Ok could you give me a specific website that I can do that with for south eastern united states?
