I wonder if anybody else has seen this problem. I bought this 2004 prius used 1 1/2 year ago, it had 100k miles then. Only thing that didnt work was the Navigation. When i turn on the NAV, the screen is not showing the current location of the car, it's showing somewhere random. When the car is moving, the marker of the NAV screen moves too. But they are not showing the car's true location.

Any idea what step i can do to fix ?

thanks for any inputs
