Now I'm unhappy. Called Garmin support, and their techies say that the maps in the 430n can't be changed from wherever they were set.
And I wasn't, apparently, the first customer to call about this. Someone had previously called, moving from Australia to the U.S., and now they have useless navigation. I'm over in Europe, with U.S. maps, and useless navigation.
Shoot, the damned base map knows where I am-- the main highways are shown, apparently, the world over. How can it be impossible for them to allow a map change/update? Heck, I know it's all about the $$$, but I'm quite willing to pay the extra bit for European maps.
