Good morning all. I updated to this pile yesterday, and once the mac book finally accepted it my edge has now decided it cannot unlock maps. On some earlier posts they suggest deleting the files. They even write them down, but the name and numbers they put do not correspond with what i have. I have tried the master reset to no avail, i have deleted the most recent downloads from what i see on the download history. but no difference, can anybody help, obviously Garmin won't bother, and the Garmin connect website is about as clear as mud and as helpful as a chocolate fire guard.
