I bought a Garmin 276C for my boat years ago and had only the marine maps. I got rid of the boat and didn't want to pay Garmin for their road map CD. This has saved my unit from being a paperweight.
I have one question. I have downloaded the excellent SE United States topo map and it is great. How do I determine if the Map Datum WGS84 that Garmin defaults to is the correct one to use with that download? Is WGS84 pretty universal?
Thanks. And thanks again for the website.
