The blue "correct guidance" overlay means you are in an area that isn't fully mapped and has nothing to do with your car - it is a limitation of the map data. You'll notice that the streets on the map show as gray instead of brown. That means they haven't been surveyed for one-way, no left turn, etc. and the NAV won't do guidance on them. If this continues with the latest 2005-2 disc, you need to open a report with NavTeq here and wait for a new map.

You should still be able to input a destination address, but it won't perform guidance (or even calculate distance / ETA) until you get onto a mapped road. Once it computes a route, you will see the route on the NAV screen, even onto the unmapped roads, though you will get a "you are not on a digitized road" voice announcement and the "correct guidance" map overlay once you leave the mapped roads.

any ideas what might be wrong with my Nav unit, it says in the middle of the screen:

"correct destination guidance not possible"

and it doesnt work. it tells me where i am but wont let me input a trip.

i have a 2004 M3 and the whole video-audio system was just replaced.

this brings something up. i noticed i could take my 2004-2 nav dvd and make a copy of it, and it works just fine in the car. Anyone have 2005-2 and want to make an ISO for me?

Over in the Yahoo! BMWNAV group, there were pointers to downloads on file-sharing services as well as a FTP server or two.

it worked when i got it back to the stealer. the only thing i can think of that might have messed it up was, i put the alpine MP3 6 disc changer in the trunk and for got to swith it to the mini-bus system before turning it on. i did so after the fact and it worked properly(cd changer).

i tried disconnecting the battery but nothing.
