Please first make sure that both the USB connector and USB cable are free from water, dust, and sand..

Connect the USB cable to your computer and then to Motion.

Press the lower-right button multiple times until the Connect to PC menu shows up.

Press the lower-center button to enter the Connect to PC menu.

A very short popup should display "Connect to computer". Motion has started USB negotiations with your computer.

Once done, the popup will display "Connected to computer".

Your operating system will display Motion as an USB Mass Storage disk.

Use your favourite online or offline route planner and export the tracks as GPX files.

These are two great online planners :

• https://kurviger.de/en
• https://graphhopper.com/maps/

Then place the GPX files in the "/tracks" folder of the disk drive.

To exit safely, the preferred method is to select the disk drive and choose your operating system variation of "Eject safely".
Or, press both upper-right and lower-center buttons on Motion.

Motion will notice the new GPX files and will convert them to much smaller and faster OAO files.

Once done, another popup will warn you of the conversion completion.

You can now add any track to the map by following this procedure : How to overlay a log or a track on the map.
