Hi Alba,
Your Montana might be set to road navigation and it tries to go back and forth between the closest road and each waypoint. To change that press the arrow on the left-hand side of the home screen to open the menu, click on "Setup" and then "Routing", now click on "Activity" and change that to direct routing, go one step back in the menu and press "Lock on Road" and change that to "No". You can now close the menu and you should be good to go.
Cheers,
Stephan
