Do you think it's even remotely possible they hadn't? Garmin is blocking updates for their own reasons. As evidence, try searching Garmin's support site on the issue -- they pointedly do not address it at all.
That seems like an unusually long time to update maps. In my experience it's usually around an hour. Though I suppose it depends on your location, internet and the amount of time since your last update.
I've just bought the Garmin - it is taking hours to update maps. Is this normal? I stopped it a couple of times blaming he computer for running slow but now I'm not so sure it is the computer.
All other downloads (GPI POI file updates) are much faster. Even my ancient GPS was quicker (till it was dropped on the floor and broke...)
I've just bought a Camper 770 which said it was going to take 3 hours to update but actually took just over 2. To be honest I was just going to leave it in a corner to get on with it, but was quite surprised when I peeked and found it was finished.
Well, I have been in update for 7 hours so far. It says: "copying files 44.8KB/s". I'm at 78% with 3 hours remaining. I updated express first. In the middle of this I ran a speedtest. My slow internet said 5.5MB/s download. Yes Garmin, your fault!
I really believe that the problem of download speed of Garmin maps is on their end. As I regularly up and download large image files and do not find the sluggishness that I do when downloading new maps from Garmin. I also want to know just how old their satellite images are with BirdsEye. I checked the map of where I live and fine that it is at least 10 years old. I see more current images on other free applications.
