Hi Forum,
I have a ZUMO 660 Australian version, with the City Navigator North America NT on an SD card (which I purchased legitimately from a store). Everything worked fine until I decided to updated the firmware from 3.5 to the most recent, (4.1 if i remember correct).
Now I get a "Cannot Authenticate Maps" at startup and it only recognizes my Australian maps. Not very helpful considering I'm in Canada!
Any ideas on how to fix this? Can I revert back to 3.5 somehow? Any way to get this working back the way it was before. It's very frustrating.
Regards,
Rowen
