Radio, Telephone and Navigation System - Self-diagnosis
Self-diagnosis of navigation system III (Route Navigation) (from Wk 29/99)
Adaption

The "Adaption" function can be used to make and store the following changes:

  • ◆ Changes to tyre size
  • ◆ Changes to number of pulses per wheel revolution (GALA)
  • ◆ Disabling/enabling of production diagnosis
  • ◆ Connection of separate or external loudspeakers
  • ◆ Changes to country identification

The individual functions are called up by way of the appropriate adaption channel number (refer to adaption table => Page01-171).

The navigation system uses the vehicle-speed signal from speedometer (GALA) to calculate distance.
