2004 C230K, CD based navigation system ver. 1/04. Shows my car in the wrong location all the time. Watch the car symbol on the map and it is 300 feet behind actual location, so the voice directions cause you to miss turns, shows you still on the freeway when you have already exited, thinks you exited so it tells you to turn left in 1000 feet when you are still on the freeway. Dealer says that's how the system is. Magnification is wrong, too. I show 7 satellites, so that's not the problem. Can anyone relate their experience? Is it accurate? I see streets with wrong names, missing streets, etc. I used the satellite to locate my house and it is perfect, use the address and I'm a block away. Can it be a software problem? Drove another at the dealer and it tracked way behind too. Help!!
