I have a 330S that is having problems.I did a n update from tottom site and now am running into problems.When you try to type in a zip code or type in a letter the next number will appear on the screen,such as type in the number 3 and you will get 4 or type in the letter R and you get S.I tried to do a factory reset as I had nothing but home added to it but did not help.Any help would be appreciated.
