Calibrating the built-in gyrosensor
Your Mobile Navigation System contains a gyrosensor as part of the positioning system.
Before it will operate correctly, however, the gyrosensor must be calibrated. To prepare for
this, stop your vehicle on an open stretch of road free of tall buildings and clumps of trees. You
will need to proceed forward for about 100 m (100 yards) to complete the calibration, so make
sure there are not likely to be any obstacles in your path.

A map of your surroundings is displayed. Your vehicle’s present location should be shown in
the centre of the map by the
C
(red) or
M
.
• If
C (black) is shown instead of C (red) or M and the map does not reflect your current location,
proceed as follows.
•Wait for
C (red) or M to appear.
•If
C (red) or Mfails to appear after five minutes, then it is likely that the GPS is unable to pick up
signals. Move to more open surroundings and stop your vehicle.
• The most probable reason for
C(red) or Mfailing to appear is that your vehicle is surrounded by thick
foliage or high buildings.
CAUTION
•
You will not normally need to recalibrate the gyrosensor again. However, if you
reinstall the unit, install it in a different vehicle, or change tyres, you will have to
repeat this process. (See "Location Status" on page 108.)
•
If you are just changing tyres temporarily, such as from summer tyres to winter
tyres, you do not have to go through this process. For these types of changes, just
switch the calibration memory. (See "Selecting a calibration memory" on page 111
for details.)
