Re: Worldwide routable Garmin maps: URL REMOVED

I have an OSM map already loaded in the computer, downloaded from http://garmin.openstreetmap.nl/.

I used JaWaVa GMTK to change the FID and all the map names.

I have downloaded another OSM map from the same site and using the windows installer have tried to install but get the error message "OSM generic routable already installed...".

Is it possible to install a second OSM map when one is already installed on the computer?

thanks
Gavin
