How to Create a Garmin Custom Map

This is a tutorial on how to create a custom Garmin map by using google earth to create a KMZ file with an image overlay. Then take the KMZ file and drop it into your CustomMaps folder on your Garmin device. In this example, I am using a GPSMAP 62s.

 

Compatible models are:

  • Dakota
  • Oregon
  • Colorado
  • GPSMAP 62 series
  • GPSMAP 78 series

Other notes: the size of the image overlay should be up to 2000×2000, otherwise you will have problem with google earth. Also resize the images to 155 dpi if they are higher. Don’t need to increase from 72dpi up, as that won’t make a difference and only will increase file size.
