Nav OS V27 has been released

@tom, @jjd

The brown screen you see is from the TV module. It looks like the update to your NAV unit did not work so the TV module has taken over as the bootup OS. Hence the brown screen. I'd make sure that when you burn a new copy of the update, make sure you use the slowest burn setting within Alcohol120% and also the media is of some reasonable quality (ie maxwell, tdk, etc...)

Ensure that you downgrade with the steps mentioned above and then follow same steps to upgrade.

If you make the update by yourself you always take the risk to destroy your nav hardware. That's the reason, why the dealer should make the updates.
I know some cases where the dealer shoot the nav computer, too. Then you'll get a new one.

In germany we took wounded mkIV's to VDO, to reset them. It's not cheap (~90$) and took a lot of time (~30 days), but there's no other known way this time.

Can you send me the address of VDO, please. Just in case that I will not be able to get the MK4 workin again.
In fact $90 is not as expensive as buying a new mk4.

I had the nav unit unplugged for the whole weekend. After that it did not boot from an older CD. (It's not been the first time I was upgrading my nav so I am quite familiar in how to create/burn the cds)

Hi.

I successfully upgraded the MK4 Navi with the V27. Thanks!

After the installation, I had no problem and drove one way. At the next day, I would like to use the Navi again. But now I have one problem. If I make my car on, and/or I make the ignition key on position 1, and turn on the Navi, the System can not find the Navi.-DVD 2006/1.

When I had still the version V26, I did not have this problem. Have you a solution?

Greetings
Jan

Ups ...

I forgot something. If I eject and push the Navi DVD afterwards again purely, the system functions again for one drives.

This must have been one of the hardest installations ever. I had the beta 26.09A and tried to install V27. Ended up with a programming error. Burned and installed another V27 disk and that disk refused to come out and wouldn't upload the firmware. Thanks for the hint on waiting until the module stops reading and then quickly pressing the eject button. Worked everytime it got stuck. I was able to upload to V26, then burned another V27 disk and it finally uploaded. 1.5 hours later, 4 CD's used, I had version 27 in my X3...what an adventure.
