CN EU 2023.20

Ah ok, I turn that off as it can lead to weird routing. Is it normally updated with the map? If so try a map reinstall using Express

map reinstall using Express:

3x time try, i send to email to garmin support,  it's their job to find a solution, to fix it,  i see a lot of user have problem with new map eu 2023.20 and download Garmin express

I along with many others had no issues, your experience is unusual. Let us know what Garmin say.

Garmin support informed me that it did a rollback with the nuvi model and maps 2023.20, now garmin express shows version 2023.10.
