I have a 2004 325xi with factory installed nav. I am at a loss here since I dont have access to the bulletins and cd's I used to have at the dealership (havent worked at dealership in 3 years now). The NAV works, shows multiple sats in upper right picture (dots around globe) and will show streets correctly as well as current location.

My problem is the display will have a message accross the screen (CORRECT NAVAGATION NOT POSSIBLE).

anyone know what is up with this.

I am thinking I have wrong cd in nav computer in trunk but like I said I no longer have access to the cds and documents I had at the dealer.

thanks
