Hi Tony,
I live in the U.S., It is a Limited Edition AWD. My Edge was delivered Nov. 12, 2010.
I do not have the letters with me as I write this. I'll get the details and let you know. I can't go to my Dealer until later this week to talk to them in person. They asked me to bring the letters in so they could read them. Sort of thought they may have received a bulletin or something about this, but not sure how a recall is handled. I'll find out in a couple of days when I show them the letters they requested.
I've read else where here at this Forum site, that most software updates must be done by the Dealer. I believe if you have MyTouch with navigation, that the navigation part can be updated when necessary by replacing the memory card with an updated version. But that's mainly for maps, P.O.I.'s etc. not the actual operating system.
I'll scan the letters and try to attach them here so you can read them.
Amy.
