Re: Worldwide routable Garmin maps: URL REMOVED

If you don't want the windows installer, you can use the _macosx.zip = Installer for Garmin BaseCamp/RoadTrip (Mac OSX)
Unzip it and place the .gmap folder to the default Garmin map folder. The location of this folder depends on the Windows version.
In Vista or W7 this is: C:\ProgramData\GARMIN\Maps or C:\Users{user}\AppData\Roaming\GARMIN\Maps (please note this is a hidden folder!)
Windows XP: c:\documents and settings\all users\application data\garmin\maps

Or you can use http://www.javawa.nl/gmtk_en.html to install the gmap maps (still needed in case of more custom maps with the same Family ID)
