By design, US TOPO v.3.00, v.3.01, and v.3.02 require the original CDs to be in the disc drive to function. This is because the map image files are not copied to the hard drive during installation. If necessary, the maps may be installed to the hard drive using an unsupported alternative method. This alternate method is provided as a possible workaround and is not supported by Garmin.

Note: BaseCamp will not display these TOPO maps unless the alternate install has been performed.

Before performing this installation, uninstall the appropiate version of US TOPO from the computer.

  1. Press Windows key + R
  2. In the text box, type appwiz.cpl
  3. Click OK
  4. Right-click on the version of US TOPO to be uninstalled
  5. Click Uninstall

Once the data is uninstalled, create a folder to save the map data from the discs:

  1. Press Windows key + E
  2. Open the C: drive
  3. Open the Garmin folder1
  4. Press CTRL + SHIFT + N on the keyboard to create a new folder
  5. Change the name of the New Folder to US TOPO

1 Create a Garmin folder if it does not exist in this location.

After creating the US TOPO folder, transfer the data from the discs to the new folder:

  1. Insert Disc 1 in the drive
    • If an autorun window appears, close the window
  2. Press Windows key + E
  3. Right-click on the disc drive
  4. Click Open
  5. Press Ctrl + A on the keyboard to select all the files and folders
  6. Press Ctrl + C on the keyboard to copy all the files and folders
  7. Open the newly created US TOPO folder
  8. Press Ctrl + V to paste the files
  9. Repeat these steps for Discs 2 and 3

After the data from all three discs have been completely copied to the US TOPO folder, run the installer:

  1. Remove any US TOPO discs from the disc drive
  2. Open the US TOPO folder
  3. Run Setup.exe
  4. Follow the prompts to complete the installation

When the installation begins, the installer may display a prompt about connecting to the internet to update the GPS device. If this occurs, select NO. When asked to confirm, select YES.

After the installation is complete, ensure that MapSource is up to date. The latest version of MapSource may be obtained at

Now that US TOPO has been successfully installed to the hard drive, the map images will display on BaseCamp and MapSource without the discs inserted in the computer.

Note: If the US TOPO folder is moved or deleted, the maps will no longer function.
