Troubleshooting
In very rare cases, it can happen that your
multimedia system does not function as you
would expect. Before you contact customer
service, please read the detailed operating
instructions on the DVD-ROM and review the
following checklist, as an apparent malfunc-
tion can possibly be remedied quickly.
Symptoms
Possible cause/remedy
System does not start, screen dark.
Ignition switched off:
• Switch on the ignition.
Ignition is already switched on, and system is on stand-by:
• Press one of the cursor buttons, the OK button, or the menu button
on the remote control.
The system switches itself off after a
period of normal operation.
At extremely high or low temperatures, the system is automatically
switched off to protect against damage. It switches on again as soon
as the temperature has returned to normal.
System does not react to actuation of
the buttons if remote control is not in
its active holder.
No batteries inserted or batteries empty:
• Replace the batteries in the remote control, or install the remote
control in its holder.
Guidance information not audible.
• Check whether “Audible information” has been activated in the
“Settings” menu.
• Check whether “Volume” in the “Settings” menu is set to minimum.
If no external speaker is connected:
• Check the volume setting of the monitor.
Some of the symbols or specifications
shown in the operating instructions are
not displayed in the status line.
• Activate the required specifications in the “Settings
–> Screen config. –> Status line” menu.
Colour of the satellite symbol in the
status line is constantly red.

An accuracy of 50 m falls within the specified tolerance limits. Please
contact an authorised dealer if greater inaccuracies occur repeatedly.

matically as soon as GPS reception is satisfactory.

the navigation computer has been set correctly.

tual traffic conditions.

gation data medium.

nently red, and no traffic information
