In the bottom left corner of the screen there is a lamp, which has more colors and 
represents more values: 

• 

 a blinking green lamp means that there is communication with the GPS and 

data is being received, 

• 

 other colors may not appear with a built-in GPS. Should any of 

these appear, this means a faulty operation of your device. 

In the top left corner there is a satellite dish to show the quality of the GPS position. 
Different icons represent different signal quality: 

• 

 red dish with a cross means there is no connection with the GPS device. 

•   white dish without arcs means the GPS is connected but no GPS position is 

available, 

•   one arc means 2D reception. A GPS position has been acquired, V7 Navigation is 

ready for navigation, but the GPS is using enough satellites for calculating the 
horizontal position only. Elevation data is not provided, and the position error may 
be significant. 

• 

 two arcs means 3D reception. The GPS receiver has enough satellites to 

calculate altitude. Position is generally correct (yet it can still be inaccurate due to 
different environmental factors). V7 Navigation is ready for navigation. 

Having explained the contents of the map, the description of the other parts of the 
map screen follows. 

There are several controls that are described on the following pages.
