I bought my Garmin c330 the summer of 2006. I let my daughter inlaw use it to go out to New Mexico, it worked good going out but comming back she came back by way of the central part of the country to go to branson mo. and she said it was working real slow, like she would find a place for the night about the time it would tell on the GPS then it quit working. I try to punch in the state and all i can get is the first letter then the center part of the screen goes blank, I have taken the face plate off like the instructions says and pushed the reset button, I have done this 3 times and its still the same.
