GPS / cruise malfunction
On 4 recent trips from Tampa to Atlanta , my gps speed info malfunctioned. At one point it changed the speed limit to 80 miles/ hr. Does not exist in FL. But several times it suddenly dropped the speed limit from 70 which was correct speed to 40 and the cruise control hit the brakes to slow car, which could quickly lead to an accident. Dealer suggested these might be old work zones, which I know is incorrect. Dealer ran computer check and said no malfunction . He really didn’t have a clue and suggested I call MB customer service. I suspect this is a software problem from the map vendor, but cannot find how to contact them. Any ideas?
