Route Calculation Error

Edge 830 Software Version 9.75

  • Reset to factory settings

  • Updated maps using Garmin Express (reinstalled)

  • Changed GPS settings

However, I still get a route calculation error when:

  1. I want to navigate to the starting point.

  2. I try to use navigation to an address.

  3. I go off-course while following a route.

What can I do? Could this be caused by a recent update?
