This is the third time this week I've been warned I need to download an update, including maps, to my Edge 1000 (I'm on an mid-2011 21.5 inch iMac). The two other times, I faithfully waited until the download and installation were complete, even getting the friendly Garmin Express screen telling me it was OK to disconnect my device.
Meanwhile, a quick look at my Edge tells me, yes, I'm up to date. What the heck, guys?
You guys have the single worst interface for Macs imaginable. Nearly every time there's an update, it takes three or four tries to get the notice cleared.
