TROUBLESHOOTING Troubleshooting In rare instances, your navigation radio may not function the way you expect it to. Before calling for technical assistance, please read the operating instructions thoroughly and go through the following check list; it may be possible to quickly remedy an apparent malfunction. Symptoms General Navigation radio not functioning. No display. Audio or map CD rejected by the unit. System switches off the sound during driving or display shows "PHONE IN/MUTE". The removable part of the unit feels warm. The display shows "Temperature too high" and the volume is lowered. The egg timer appears and the CD cannot be ejected. The telephone is not being detected even though it has been connected to the radio. Unit not functioning / Not suitable for VW/Audi vehicles Display still showing "INIT". Will not function. Radio Poor radio reception. The display shows the frequency instead of the station name. The required station cannot be set with automatic search. The display shows "Tune to next TA station" and a warning tone sounds. No traffic announcements are being made (CD, CDC or MUTE). CD player / CD changer Distorted sound / skips during CD play. CD player does not work. No sound during CD play. Problems with new copy-protected audio CDs. 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 initialization 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 recognized 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. 57
