Navigation - Overview
Route Guidance Position
Under certain driving conditions, it is possible that the route guidance may be inaccurate. Some examples are shown below:
•Route guidance may occasionally be given where no turn is required.
•Deviation from a route may cause incorrect guidance until the route has been recalculated.
•If there is no road or only a narrow track to the final destination, guidance will be given to the nearest point possible.
•No guidance is given while reversing.
•If driving at high speed or on very dense road networks, it may not be possible to recalculate the route in time for the next instruction.
•On familiar roads, personal route preferences may not always be followed.
Time and Distance to
Destination
When a route is calculated, the estimated time required to drive the route and the total distance to the destination are determined. The time is based on the vehicle travelling at the current speed settings for each type of road (residential, main road and freeway). The distance is based on the current route preference settings, e.g. Use Toll Roads Yes/No, see ‘Route Preferences’, page 69.
While driving under guidance, the estimated time (if selected) and distance remaining to the end of the route are shown on the screen.
Alternative Routes
During route calculation, up to three possible routes are calculated. The first route is calculated using the current route preference settings. The second route is also calculated using the preference settings, except that for Minimise Time/Dist., the alternative setting is used. For example, if Minimise Time is currently selected, then the second route will be calculated based on Minimise Distance, with the other settings as selected. For the third route, the system tries to find another alternative using different combinations of the preference settings. If a suitable alternative is not possible, only the first and second routes will be shown.
Languages and Distance Units
The screen text and voice guidance are available in a number of different languages. For the list of available languages, See ‘Changing the Display Language’, page 74.
Distances are shown on the screen and given in voice guidance, either in miles or Metric units (kilometres and metres). For information on changing the selection, see ‘User settings’, page 19.
