Central Console Navigator operation check

Connect

• Check that the map disc is consistent with the vehicle model.
• In NAV mode, check that the number of satellites is at least 3, which indicates that the satellite reception is correct. If the reading for the number of satellites is less than 3, then the reception is not good enough to locate the vehicle. It is probably a question of insufficient coverage. In this case try and move the vehicle to an area where there is good reception or compare the reception with other cars located in the same place.

The satellite reception test should be carried out in an open area. In this case, without a comparison it is impossible to say whether or not the navigator is defective. If, on the other hand, the comparison reveals even worse reception, check the connection of the satellite aerial, the electrical continuity, the correct power supply and, if necessary, test with different equipment that is definitely working properly.

For the road test:

• Exit in NAV mode
• Check that the arrow moves consistently with the vehicle speed, otherwise check the presence of the mileometer signal.
• Check that the arrow changes direction in line with the vehicle. If the arrow does not change direction this means that the gyroscope inside the map reader is broken and the Connect should be replaced.
• Enter a destination and activate route calculation. Wait for the first instruction and the route to appear on the screen and check that it is correct.

Irregular instructions: before or after junctions, arrow out of position - may be due to CD maps that are not up to date: a missing instruction stems from the fact that a road is not on the map because it has not been processed in digital form or the road network has been changed compared with the one on the map.

The navigator calculates the position of the vehicle both by means of the satellite signal and using the wheel rpm and the internal gyroscope bush signal. Problems of accuracy may arise when:

• The odometer speed signal and reversing signal are not received correctly.

Occasions when the navigation system should be initialised:

• The vehicle is being transported with the battery disconnected and travelling in a tunnel (the navigator loses the references).
• Immediately after having changed the tyres (since the wheel rpm/distance conversion factor is not accurate).
• On replacement of the Central Console

To initializethe navigator it is necessary to drive about 50 km in optimum satellite reception conditions.

If all the tests have highlighted no defects, then the problem lies with the Central Console, which should therefore be replaced.
