A display of GPS status appears. At the same time, a graphical representation of the following
information is shown:
1 The average strength of the GPS signals from the satellites (level 0 to 3 as indicated by the
satellite icon at the top left of the screen)
• If no signal is indicated, check the GPS aerial and locate it such that the signal strength is a
maximum.
2 Your present longitude and latitude (calculated by the GPS)
3 GPS positioning mode (--, 2D, or 3D)
• For “2D” and “3D” definitions, please refer to “What is GPS?” on page 130.
4 Coloured satellite icons representing the approximate position of the GPS satellites in the
directions of the compass
• The colour of the icons indicates the signal reception status. Gray is a known satellite from which
no signal is being received; red represents a satellite whose signals are actually being used for
positioning; yellow means that signals are being picked up but are not currently in use for
positioning.
