Possible cause / Remedy
• Switch on the ignition.
Ignition is already switched on:
System is in stand-by mode.
• Push one of the keys on the remote control.
Monitor connector is not locked correctly.
• Slide the monitor onto the support (connector) until it clicks into
position correctly.
At extreme high or low temperatures the built-in protection circuit
switches off the system automatically.
• Operation of the system is resumed as soon as the temperature
returns to a normal level.
You are in a very densely digitized area. The navigation system has to
read a large amount of data from the CD-ROM.
• Make sure that you entered a destination address.
Car is not on a digitized road.
• Drive in the direction of the displayed arrow to a digitized road.
• Wait a few seconds until the system has initialized (options appear in
highlighted letters).
• Make sure the GPS aerial is not covered by any objects.
• Drive outdoors, if you are in a garage, a car park or a tunnel.
• Make sure that the volume is not set to minimum.
• Make sure that an appropriate CD is inserted with the printed side
facing up in the navigation computer.
The CD might be dirty.
• Try to clean the CD with a special CD cleaning fluid.
Address book is full.
• Delete one or more entries no longer required.
Inaccuracy of a max. of 30 m is possible.
• If you frequently discover greater inaccuracy, contact an authorized
service centre.
Bad GPS reception for a longer period of time (for example caused by
interference). When sufficient GPS reception is resumed the position is
corrected automatically.
• If necessary wait a few minutes.
It is possible that the car position calculated by the navigation system is
currently wrong.
The route may have been changed and does not correspond with the
information stored on the map CD.
