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 a 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.

If I eject and push the Navi DVD afterwards again purely, the system functions again for one drives.
When I had still the version V26, I did not have this problem.
Have you a solution?
Greetings
Jan
