If your Garmin GPS receiver supports Custom Maps, the Send Map to GPS command in ExpertGPS can send any map or aerial photo to your GPS so you can use it to determine your exact location in the field.
To send a custom map to your Garmin GPS, do the following:
The Send Map to GPS dialog will appear, allowing you to customize the size and scale of the custom map.
Width
Enter the width of the image.
Height
Enter the height of the image.
Scale
Enter the map scale of the image. This will already be set to the current scale of the map in ExpertGPS.
Send Map
Click Send Map to create the custom map and save it to your GPS.
Click Send Map to save the image. The Save As dialog will appear. Select the image type
in the Save as type: list. If you checked Calibration File, a worldfile or map calibration file will automatically be created in the same location as the image file.
After you are finished exporting your map, do one of the following:
On the Map menu, click Hide Send Map to GPS Window.
Click the close box on the Send Map to GPS window.
