Reference Data
GPS Positioning Quality Indicator
Online Road Information Saved in Route Search
The GPS reception quality icon at the top right of the menu screen
indicates the current accuracy of positional information.
This unit can provide you with even better routes, if real-time traffic
information (TMC: Traffic Message Channel) is available.
If public traffic data is broadcast at your location, this unit automatically
takes into account the traffic data received. You do not need to set
anything in the program. The decoded information will immediately be
used in route planning. The moment unit receives traffic information
that may affect your route, the program recalculates the route, and this
unit will continue with a new route that is optimal based on the most
up-to-date traffic conditions.

Explanation
The software is not connected to the GPS receiver. Cannot
perform GPS navigation.
Products with a built-in GPS receiver are always connected. This
icon is not normally displayed for those products.
Although the software is connected to the GPS receiver, the signal
is too weak to measure the GPS.
Cannot perform GPS navigation.
Only a few satellites are transmitting. Positional information is
available, but altitude (elevation above sea level) cannot be
calculated.
GPS navigation is possible, but large positional errors may occur.
Elevation above sea level is available, and measurements can be
performed in 3D.
GPS navigation is available.
