A friend has just updated his maps on a Garmin 660LM and now gets a " Cannot unlock maps" message each time the unit boots up.
The Map info shows that it has the latest CN2016.10 installed on to the SD card and the unit seems to be navigating fine, but we still get the error message. We are downloading direct to the unit from Garmin Express to which the unit is registered. He did have another GPS registered on Express which has been removed.
So far we have tried:
Formatting the card
Soft reset of the 660
Removing the card & loading directly to the unit.
Unregistering / re-registering the unit on Express.
Any other ideas before we contact Garmin?
Thanks
