I'm one of those who upgraded a One to a 2GB card with North America v710maps. Everything had been working great for several months, with the Home program recognizing that although I have a One, I'm entitled to MapShare updates for the NA maps actually installed on my device.
Suddenly, within the week or so, Home doesn't seem to recognize that I have NA maps, and it doesn't download any MapShare updates. (In fact, Home wants me to download & install USA & Canada 665!). Home says
"Your map is up to date", and that I have "0 MapShare map corrections in use"!
My 1-year timeframe for updates hasn't expired, and I'm afraid all those MapShare udpates are no longer on my One.
Ideas?
