Working with Garmin Data Cards

You have the option to transfer all data types in MapSource to a removable storage card. The storage card accepts all data types, but only some Garmin GPS devices are capable of reading all data types. All Garmin GPS devices, however, are capable of reading the map data.
The following are possible scenarios when transferring MapSource data. NOTE: Not all data transfer options will be available in MapSource unless you own the specific GPS device:
  • Transferring only maps to the storage card: The storage card is completely erased before adding new maps.
  • Transferring maps as well as other data (waypoints, routes, and tracks): The storage card is completely erased before adding new maps, waypoints, routes, and tracks to the storage card.
  • Transferring only waypoints, routes, and tracks (no maps): There are two scenarios. 1) If the data card currently has maps stored on it, the maps stay on the storage card and the other data is erased and replaced with new data. 2) If the data card contains no maps, the storage card is completely erased and replaced with new data.
NOTE: Preloaded (pre-programmed) BlueChart or Fishing Hot Spots data cards should not be used in the USB Programmer or in a GPS device for saving MapSource maps. The preloaded data will be lost. If you have a BlueChart or Fishing Hot Spots data card in your GPS device, remove it before transferring maps sets to avoid losing the preloaded data. If you choose to overwrite the preloaded data on a BlueChart or Fishing Hot Spots data card, Garmin will not replace or recover the lost data.
