NAVIGATION "HOP" CAN CAUSE INCORRECT DIRECTIONS
The customer may complain that the positioning icon on the map display can occasionally "jump" off the route and back on again. Sometimes the display
will appear to be moving parallel to the route of travel. In some circumstances these symptoms could lead to incorrect directions at intersections.
A vehicle warming up in cold temperatures may be more susceptible to the symptoms.
VERIFY UPDATED NAVIGATION SOFTWARE IS INSTALLED
A revised software release V1.20 for the factory installed MK III navigation computer has been introduced. Disc VDW000020 can be used to update the
navigation computer software to the latest specification. To ensure that your customer has the revised software a system software update should be
carried out "Free of Charge" at the next service opportunity on vehicles within the VIN range.
