Loading maps on 62S on the SD card.

[borskies]

I have a 62S and have been loading topo maps on a SD card. I went to "openstreet.com" and down loaded a routable map and when I uploaded it to the 62S it removed my topo maps? So I reloaded the topo maps and it removes the driving routable maps. I diablaed the maps in the unit before up loading any new ones but that didn't work. Do I need another SD card for topos and driveable maps? I loaded a Colorado topo and thought the openstreet would just lay over the topo. Not so.

Thanks

The is normal operation.  Both MapSource and BaseCamp send map data to the GPSrs in a file named gmapsupp.img and will overwrite any existing file by that name.

After sending a mapset to the GPSr, rename the gmapsupp.img file to some appropriate name with a .img extension.  Do this with each mapset sent to the GPSr.

It is a good idea to make a backup copy of all the files which came on the GPSr incase one or more becomes corrupted of deleted.

I use Basecamp so if I just rename the file once it is on the SD card it will not be over wrote when I try to load another map?

Yes, you can simply change the name to something else. However, are you running the current version of Basecamp/Mapinstall? If so, it should automatically generate a unique map name if you are connecting the GPS to your computer (as opposed to using a card in a USB reader).

Yes I'm connecting my gps to my computer but it doesn't generate a name other than what it was downloaded as. Also I am running the latest version on Basecamp and map installer.

Look in the Garmin folder on both the memory card and GPS itself. What .img files do you see there?

I have to look at it when I get home later.
Thank you for you response.
