Tunnel View; Route Calculation And Recalculation - Audiovox NAV 104 User Manual

5.1.3 Tunnel view

When entering a tunnel, the map is replaced with a generic tunnel image so that surface
roads and buildings cannot distract you.
The top-down overview of the tunnel helps you orientate yourself. The remaining distance
in the tunnel is also displayed.
After leaving the tunnel, the original map view returns.
This feature can be turned off in Settings (page 232).

•
Route planning methods:
•
the speed limit on all roads. Usually the best selection for fast and
normal cars.
•
of all possible routes. It can be practical for slow vehicles.
•
the fuel consumption data given in Route settings (page 224). Travel
cost and CO
