GPS Position Quality Indicators

You can nd useful information in the top corners of menu screens.

In the top right corner, the GPS reception quality icon shows the current accuracy

of the position information.

Icon Description

iGo primo has no connection to the GPS receiver: GPS

navigation is not possible.

Devices with a built-in GPS receiver are permanently

connected. On such devices, the icon does not appear in

normal circumstances.

iGo primo is connected to the GPS receiver, but the

signal is too weak and the receiver cannot determine the

GPS position.

GPS navigation is not possible.

Only a few satellites are received. Position information is

available, but elevation (altitude) cannot be calculated.

GPS navigation is possible, but the position error may be

signicant.

Altitude information is available, the position is a 3D

position.

GPS navigation is possible.

Stored Tra c Information In Route Planning

The recommended route is not always the same between two points. Oine

statistical trac information (historical speed information or trac patterns)

can be taken into account in the route calculation based on the time of day and

the day of week whenever suitable data exists. This function is subject to data

availability.

Smart Routes with Stored Statistical Tra c Information

If statistical trac information is stored with the map data, iGo primo can take

them into account when planning a route. In normal cases, these statistics help

you avoid usual trac jams on the given day of week in the given hour but in

some cases like on public vacations that fall on normal weekdays, they can be

misleading.
