Possible cause / remedy
• Check the fuse (unit and vehicle) and the connections
(see installation instructions).
The CD may be dirty.
• Clean the CD with a special CD cleaning fluid.
Speedometer signal connected to the wrong pin of the power supply
connector.
• See pin setting ISO chamber A in the installation instructions.
No error. The unit always generates some heat.
An integrated safety circuit prevents the temperature in the unit from
exceeding a certain value.
• Allow the unit to cool (set lower volume) and wait until "Temperature too
high" disappears from the display.
• Disconnect the power supply from the unit for at least one minute then
reconnect it. If this does not work, return the unit to the Service department.
• Call up the initialisation menu, select "Telephone ON" and select "12 V" for
Nokia hands-free units.
The power supply connector pin assignment for VW and Audi is not the same.
• Use the VDO Dayton MA1910 adapter for the connection.
The unit is faulty.
• Take it to the Service department.
• Check if the antenna is completely extended and correctly connected.
• Verify that the supply power negative pole (brown lead) is correctly
connected to earth (vehicle chassis).
If the unit is being installed in VW and Audi vehicles, you will need a power
supply adapter for the antenna.
• Use a suitable adapter (e.g. Votex).
The unit is set to a station that does not transmit RDS signals or the
transmitter is too weak.
The required station is too weak.
• Set required station manually (manual tuning).
• Check if the antenna is completely extended and correctly connected.
"TA Scan" or "TMC Scan" has been activated
The radio only tunes to stations with traffic news or TMC information.
• You may need to deactivate the "TA Scan" or "TMC Scan" function.
Tuner standard (tuner grid) wrongly set (EUR / USA).
• Check the "Tuner Grid:" option in the "Radio" menu.
"TA Scan" is switched on, the selected station, however, is too weak or does
not transmit traffic announcements (TA).
• Deactivate the "TA Scan" function or set another station.
• Activate the "TA Scan" function in the "Information" menu.
Player cannot read CD. CD is damaged or soiled.
In cold weather conditions, condensation may occur on the laser.
• Wait approximately 5 minutes until the condensation evaporates.
Some CDs contain multimedia data which is not recognised by the unit.
• Select the next track until music is heard.
Some copy protection procedures are incompatible with accepted standards for
audio CDs. This is not a fault on the unit.
