[porsche tech]

I have onboard GPS in one of my cars and when I pull out of my garage it takes several minutes for it to figure out where I am. During those several minutes the picture on the screen usually shows me driving around in the ocean. Bought the car used, would never pay for it on a new car…iPhone works great! Back when I was still working, Porsche had the worst GPS. Best one I saw was a customer had a hand held Garmin suction cupped to the navigation screen on his Cayenne.
