Have any of you ever noticed your map screen shrink down to where the map is only displayed on about 40% of the screen? I've seen this 3 or 4 times. If I turn it off and then back on, the screen returns to normal size. Another thing i've noticed ( I saw it a couple of times in my old vista too) is erroneous max speed indication on the trip computor page. Today it said my max speed had been 103 mph and another time it said that I had some how managed to get my Coca Cola van up to 174 mph!!!! :-) What's the deal? God bless! Eric
