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
Baz
 
what computer is he on and what version of basecamp are you using? Might find that he needs an older version of basecamp to see/unlock maps. There is also a google reult somewhere for creating a machine account and giving garmin program admin rights to execute the unlocking etc

Probably missing .gma file.

Had a similar problem after an update. Gave garmin a call, straight through as soon as 'open' on the Monday morning. Diagnosed as missing .gma file. I was sent the file by email and instructions on how to use. Problem fixed. Still have the file and instructions somewhere if you don't get through to Garmin. May be worth a try.

There was a post on the first link which did the business:

" Cannot unlock Maps

I removed 'gmapsupp.img' from my Garmin, & then reinstalled the maps from within Garmin Express. My Edge no longer shows the Cannot unlock Maps warning when I start it up."
