I started looking for the maps a few days ago and quickly ruled out buying them - the official Garmin Topo maps of Spain and France are over $600 US. I didn't really want to pirate them, but while searching some of the back alleys of the internet I found out about OpenStreetMap, which is a kind of cartographic wikipedia. There are a few ways to play with and download the maps on OpenStreetMap itself, but to get them onto your Garmin GPS you need to checkout another site called: Free routable maps for Garmin brand GPS devices (garmin.openstreetmap.nl). Which is free and awesome.
|Selecting an area around Bordeaux|
|Free OpenStreetMap from garmin.openstreet.nl of Bordeaux, France.|
|The same area from Garmin's TOPO France v.2. Not free, at all.|
The resulting map looks great. I haven't had a chance to ground truth it yet, but in Mapsource, it looks as good or better than the $600 Garmin product. However, I did notice that when I downloaded and installed a second set of maps it overwrote the first set that I'd download, even when I changed the folder name. If someone figures out a way to fix or avoid that, I'd be grateful. Even so, I'm definitely keeping Free routable maps for Garmin brand GPS devices (garmin.openstreetmap.nl) in my bookmarks.
