After searching this forum, I see that 2010 models had the problem where the Navigation System would default to Washington D.C. I have a 2012, and today I attempted to enter a destination, but first I had to agree to some legal declaration, then it had me in Washington, D.C. so I had to change it back to Florida. I guess it's not only 2010 models with this problem. I saw that folks that had this problem also had an issue with the clock. I need to check that and see if that is also an issue. It seems the fix was a firmware update.
