Zumo 660LM deranged.

I downloaded the 2024 Euro map updates for the area I need. My Zumo 660LM suddenly took me off the Autobahn route I had onto lots of little local roads.... now it won't talk to me and it would not find an address that another routing app found instantly. When I try to use it, it tells me there are no roads there... seems I should simply delete the newest maps and reinstall?

That would be a good first step.

I'm not sure which the actual updates are. I've deleted all my trip logs and favorites, but not sure which the updates are.

thanks, Zigy/Currently in Belgium

These are the files dated as having been installed downloaded in spring 2024 just before starting this trip.

Are these the ones safe to delete?

I don't have a 660 and this is more a device issue but those should be safe to remove. You may be better asking at https://www.zumouserforums.co.uk/
