Navigation Update

[richmondguy]

Thanks to the great help of jdbretz, my new disc is up and running. But I don't notice any difference. What is the difference between the disc discussed in this forum and the 2009.1 disc I was previously running?

You may not notice any difference if there hasn't been any new construction in your area. The update includes those new roads and updated POI information.

someone mentioned there is red light camera info in this update - I don't see how I could get it to show up.

Hit the Menu button, go to Navigation, scroll to the right and select Information, On Location, choose Red light/Speed Cams, conduct a search. You don't need to select any of the results, just return back to your map. The icons will now appear on your map for the Cameras in your area. Keep in mind that if you search later for a gas station or restaurant, you will have to go back and get follow the instructions above to get them to show back up. The map retains the icons for whatever POI you last searched for.

According to this thread, the maps for the 2011 cds are provided by TomTom.

I noticed this week that the 2011 cds were giving me some odd routings so I finally ran the TT app on my iPhone at the same time and the app did a better job that the BMW nav in terms of routing choices.

I know OKC might not be a good test case but just wondering how the 2011 maps look to others.

For whatever reason the routing on BMW nav sucks compared to a TomTom, Garmin, Google maps, Etc. I usually enter an address into the Nav, then compare it to what I get on Google Maps on my blackberry. When there are differences, I choose Google's directions. For local address' the BMW nav does fine, I just don't trust it for the best route on any long distance trip.

Can you think of anything worse for a GPS system?

I agree completely! The Nav in my 335i once routed me 67 miles out of the way on a 180 mile total distance trip. Luckily I knew how to get back and caught it before I started following the directions. The biggest thing I hate about it too, is even when it routes you the wrong way, it will continue to tell you to do a U-turn for the next 20 miles before it updates and send you the way you should have gone in the first place. Bmw gets a HUGE on their routing protocol. I haven't used the newer hard drive based Nav but hopefully they fixed all these issues.

I am convinced it isn't the "BMW Routing Protocol", but rather the 'TeleAtlas Data' that is defective: Buried within the data is a 'discontinuity' or 'defect' that the system views as either an "open" in the road, or a section with a very, very low average speed- like a negative number. Hence the algorithm does not choose it as a viable path... and it is not until you cross over the defect that the algorithm then no longer sees the discontinuity and can properly route.

I am convinced that there are broad and manifold data defects in the teleatlas dataset BMW is selling us....
