Moeyhc & tympg,
Just to elaborate on the issues, when I downloaded maps from OSM and when load into sd card the Nuvi reads them as OSM generic routable.
Having changed the mapset names as per moeyhc suggestion didn't solve the issue cos when displayed under map/info I got beside box for ticking.....OSM generic Routable and in finer print the mapsets I renamed.It doesn't allow me to have diff. listing for the diff maps.
Maybe it has something to do with the way the maps are ''linked'' cos with other maps I don't have such issues.
Anyway I've 'bout given up . it doesn't matter i can always load one map at a time.
I'm not savvy at all with computers .
Thks & rgds
I believe we have a disconnect between what you ask and the solution provided.
The members solution is changing the file name as displayed but managed by a PC operating system. You change names and put them in the Nuvi SD card/map directory and this can only be seen through a PC
What you want is the ability to rename the maps as displayed in the Nuvi Map Info vs the solutions by members who gave solutions. This requires a mapping software to edit the file and to change the name on condition you have the source code.
As you are not wanting to be involved more in depth into the technicalities of "mapping", putting into different SD card is on solution with the label name on it is one solution but this involves carry around a bunch of SD cards. The other solution is to put all maps into one SD card/map directory and maintain a written database co-relation between the map file name as displayed by a PC vs the actual map name.
