Route calculation error on Forerunner 965 after updating to 20.29

hub 2 months ago

Hi everyone,

Since updating my Garmin Forerunner 965 to version 20.29, I've been experiencing issues with the navigation feature. Either it won't start at all, or it starts but shuts down after a few minutes, displaying the following message:

"Route calculation error. Missing routable roads in this area."

The issue is not related to my location, as I’m on normal public roads where navigation has always worked perfectly fine in the past. I've already reinstalled the maps via Garmin Express, as suggested in another thread, but the issue still persists.

Has anyone encountered this problem or have any other ideas on how to resolve it?

Thanks in advance!

I went on Garmin Express and redownloaded the Canada map and it works fine for me now. Give that a try if you haven't yet for the map that you use

I am also having this issue

Me too. This is usually preceded by a map/navigation screen which is empty (only direction arrow and a scale). Using map is non-navigation mode is fine though.
