2.4.10.2 Camera directions

A speed camera can measure the speed of one direction of the traffic, both directions, or even several
directions in an intersection, when they are mounted on a rotating base. The same directions apply to
red light cameras. Clarion Mobile Map warns you only if you drive in a measured or possibly
measured direction. The measured direction of the camera appears with the following symbols:
Icon
The camera checks speed in the direction into which you are driving.
The camera checks speed in the opposite driving direction.
The camera checks speed in both directions on the road.
The camera can check speed in any direction.

2.4.11 Speed limit warning

Maps sometimes contain information about the speed limits of the road segments. This information
may not be available for your region (ask your local dealer) or may not be fully correct for all roads on
the map.
You can configure Clarion Mobile Map to warn you if you exceed the current limit. Tap the following
buttons: , ,
When you exceed the speed limit, a voice message is played using the selected voice guidance
profile.
These speed cameras work in pairs, and do not measure your current
speed but your average speed between the two speed cameras. Both
identify your car and record the exact time you pass them. They use the
difference between the two points in time to calculate your average
speed.
Clarion Mobile Map warns you when you approach one of these speed
cameras, but as you pass by, the warning stays on, and your average
speed is measured until you reach another speed camera of this type. If
your average speed exceeds the speed limit between the two speed
cameras, you receive the same special warning sound as with the other
speed camera types.
In the rare case Clarion Mobile Map cannot register the moment you
pass the second speed camera (for example, it is placed at the exit of a
tunnel where GPS position is not yet available) the warning continues.
Just tap the speed camera symbol displayed on the screen to stop the
warning.
Tap again to display the second route event with the possibility to open
the Itinerary.
These cameras check if you obey traffic lights. The warning is similar to
mobile speed cameras: as there is no speed limit given, only the
proximity is announced.
