Thanks a lot for those links. I did download those two files. The only question I have is : when you burn it to a disk - do you load one for East and one for West region or you load two files to the same disk ? Thanks a lot.

For 2010 and newer navigation DVD's, BMW changed their provider for Maps from Navteq to Tele Altas. They now release them in 2 Regions (East and West) and are 2 separate discs. You will burn each of them separately and select the slowest burn speed your computer offers. After you're finished burning the DVD, put whichever region pertains to you in, you'll see a notice on the screen saying new maps detected and to shutdown your idrive for 5 minutes (or something similar). Turn the car off and wait, or you can push both eject buttons and the mute button all together and it will reboot your idrive system and you'll be up and running with the new maps. :thumbup:

*EDIT* You do know you need to the burn the the ISO files with a program like Nero or any other one that handle ISO file (an ISO is image of the info on the original dvd). You can't just add it to a dvd as a file and burn it, it won't work. I'm not trying to insult anyone's intelligence, just thought I would cover that and potential save someone from wasting dvd's and wondering why they don't work.

Good advice. On a PC, just use the free ImgBurn program and preferably Verbatim or Taiyo Yuden DVD-R (but others should work too).

I tried to download the zipped files from the link. The download took 1 second and the files are "invalid". Does anyone have the files? Will this update work on an '07 X5?

The links to the zipped files don't work very well because you will often get disconnected from the hosting server before the file completes, which is what happened in your case. These files are very large and even on an extremely fast internet connection should take at least 30 minutes and probably closer to 1-2.5 hours. I recommend using the torrent links. Send me a PM if you aren't familiar with torrents and I'll explain everything to get you set up.

Does each require dual-layer discs? Can't tell cause they're zipped.

EDIT>> looks like the east is just 4.1GB unzipped... surprised since the previous one (also 2 parts) needed DL.

No, not dual-layer discs (for 2011).

If I remember correctly, the 2010 version was not dual layer either. The initial 2009 version was but then BMW released another version for 2009 maps that was not DL (probably because of problems that some cars were having with DL).

That is correct, 2010 was single layer discs as well.

I would gladly pay for a single double layered DVD like we got in 2009, but I can't imagine the joy of going 120 mph on I-40 when the nav tells me to change CDs as I approach AR state line 4 times a year. I suppose one will also always get the new cd warning asking to stop the iDrive for 5 minutes.

The new maps warning will only appear once when you first insert either East or West disc, and you can switch freely between the 2 with no need to shutdown the idrive. I do agree with you though that a single dual layered disc would have been much more convenient and practical.
