How to install contour lines on Garmin Edge devices?

Garmin Edge cycling devices come with preloaded maps.

However, the preinstalled Garmin cycle maps, which are based on OpenStreetMap data, have a disadvantage: they do not have any contour lines. Although a shaded relief can be activated, it does not replace the helpful contour lines.

But you can install contour lines!

Where can I find files with contour lines?

• garmin.opentopomap.org (worldwide) (SRTM)
• osm.thkukuk.de (european countries) (SRTM)
• speichenkarte.de (european countries) (SRTM)
• kleineisel.de (Germany, France, Iran, Nepal, Scandinavia, Alps, West Africa) (SRTM & LIDAR)

Contour lines based on SRTM data are somewhat angular in contrast to LIDAR data!

How to install contour lines?

• Download and unzip the files
  • Names
    • garmin.opentopomap.org: Garmin contours
    • os..thkukuk.de: … SRTM …
    • speichenkarte.de: e.g. Italien
    • kleineisel.de: … lidar …
• Copy the IMG files with the Windows explorer or Mac finder to the folder "\Garmin"
  • Edge in mass storage mode
  • Use the memory card if available (e.g. Edge 1030)!
  • If you like you can rename the IMG files
• Unplug and restart your Edge
  • Activate the map containing the contour lines (activity profile > navigation > map > map information)
  • Activate the function "draw contours" (activity profile > navigation > map)
• Enjoy!
