Service Mode Menu
If you have a MK2 Nav System (female voice), you can bring up a Service Mode Menu as following:
- Set ignition to pos. II
- go to "settings"
- push the MENU button for at least 20 seconds
- The service menu has some TV options, GPS Data and telematik. Unfortunately, I only have an MK1 system, so I cannot tell you exactly, what youcan do with these options.
