Downloading mapsets

Every time you download it wipes the entire memory card. You have to select all the maps you want stored on the card each time you add a new map. To keep from selecting all the maps everytime you want to download you can save the file in your mapsource software then just add or delete maps from your original map list.

All the mapsets that are installed in your PC should appear in the menu bar on a dropdown list. If you click on it you should see "bluechart" city navigator" etc, if you installed them correctly.

Choose one of the map sets, such as bluechart, from the dropdown list and all the maps from that set should appear on the screen.

As you select individual maps from the map set they will be loaded onto a maplist wich should appear under a tab on the left side of your computer screen.

Then go back to the menu bar and pick your next mapset, such as city navigator. A new map set will appear on the screen but the maps you selected from the previous set will still be on the map list on the left side of the screen.

I hope this helps. Please reply if you have questions about my response.
