Thanks to Ferri, V26 is available. I loaded it this morning on my X5 with a MkIV nav computer and it went as smooth as silk. Below are some pictures showing the update progress and the end result.

Note that this update is for MkIV nav drives only. If you have a MkIII, do not even consider using this release because it is reported to have some issues that could render your nav drive inoperable.

A few notes on the upgrade, but first a reminder that there are risks to doing the upgrade on your own, so do so knowing that risk is present. Although rare, problems can occur if update steps aren't followed properly or there are issues with the media. Such conditions can cause problems with the nav drive which may not be recoverable.

- The image files have been rar'd (compressed), so you will first need to un-rar them. I use a program called TugZip, but there are other programs such as WinRAR that will also do the trick.
- Once you have uncompressed the image files you will need to burn them to a CD-R using a program called Alcohol 120%, which is available as a free 30 day trial here - http://trial.alcohol-soft.com/en/download_120.php
- Burn the disk using a high quality CD-R disk at the lowest possible burning speed using these steps:

1. click on "image burning wizard" then click "browse" and find the folder that you extracted the two files to.
2. click on "bmw v26 software" (there's only one to choose) and click "open" it.
3. Under Image file information, it should list the two files and the total size is "288.66 MB". Click "Next"
4. If you didn't insert a high quality CD-R earlier, insert it and set the write speed at the slowest one (mine was 2x). Make sure the CD/DVD Recorder is set on the right drive.
5. Click "Start" and it should start burning. Once it reaches 100%, it'll be done and the disc will eject on its own.

- Once the disk is ready, follow these steps

1. Go to your vehicle and turn the ignition switch to the first position. Let the navigation system boot up and get into a normal operating mode.
2. Leaving the system on (never turn the power off during these steps!!), go back and eject the navigation CD from your drive unit.
3. Put in the V26 disk you created into your drive unit. Watch your screen and be patient. It says it will take about 6 minutes to do the upgrade, but it doesn't take that long. When it’s done it will eject the CD automatically.
4. Put your navigation CD back in the drive and make sure everything is working properly.

Here are some screen shots from my update to V26















As you can see from the last couple shots, the screen has a whole new look and feel - and my first reaction is - very nicely done

Now for what you have all been waiting for - the download link - or http://bmwnavigation.com/software/Na...tware_Updates/
