I was driving home from work and about 15 mintues from home, I look down at the Nav screen and it is shutting on and off rapidly at about a pace of 40 times per minute. Next, the face plate starts to rotate down like I want to put in a tape, but stops half way through and starts to go back up. Up, down, up, down...this goes on until I get home. No matter what I push or do, it still is going crazy and driving me nuts. :hihi: Oh well, I am bringing it in for service tomorrow, but has this ever happened to anybody? If the nav system is bad and they have to order a new one under warranty, do you think they would do the DVD version if I paid the difference and/or what would the difference be?
