Why did my Terrain Navigator Standard Edition stopped importing from my GPS?
One possible way is communication between software and the GPS and that communication is affected by:
Drivers installation. Check that your device is properly recognized in Device Manager (Start > Run > devmgmt.msc).
Faulty cable. Replace the cable and then check its behavior.
Wrong settings. Start the GPS device and make sure that it's configured properly.
The GPS device also has various working modes. You can switch between them to see which one works better. More info here: https://tnp.uservoice.com/knowledgebase/articles/172079-why-do-i-get-a-gps-error-about-two-modes-of-opera
