I just tried to update the maps on my Zumo 660 that I've had for about 2 years and have updated numerous times with not problems. I started Garmin Map Updater 3.2.2, it found my 660, I agreed to the terms, it showed me the new version of the maps, I clicked continue, it said it was connecting to the server then a message popped up "This Garmin GPS is not eligible for this update because a previous map version is not installed." What the heck!!!!
