Global Positioning Satellite Status Icon and Screen
GPS – The GPS symbol is placed at the top right corner of the screen.
The color of this icon and the number displayed have the following significance:
Red – A GPS receiver is not connected or the power supply is interrupted.
Orange + number of received satellites – A GPS receiver is connected, but the received
signals are not strong enough for navigation purposes (for example, inside a tunnel).
Green + number of received satellites – Strong signal; navigation may begin.
Tap the GPS icon to display the current GPS status:
GMT – Greenwich Mean Time (time in London, without daylight saving time).
Longitude /Latitude – current position; indication of east longitude and north latitude.
Satellites – Number of received satellites. At least three satellites must be received for
navigation purposes.
HDOP – Horizontal Dilution of Precision indicates the quality of position determination.
Theoretically, any value from 0 to 50 can occur. The smaller the value, the more accurate the
position.
Speed – Indicates your vehicle’s current speed.
Position – Indicates the address of your current position.
Save – Tap this button to add the current address to the saved destinations list.
Quit – Tap this button to exit navigation and return to the Main Menu Screen.
Command Buttons with Caption
Command buttons – You will find command buttons with captions on almost every screen.
There are three groups of command buttons:
1. Command buttons with a defined functionality. These buttons are designed to execute
a functionality, which is indicated by their caption: Save, OK, Cancel, Select map, One
destination, etc.
2. Buttons to select one of two functions. Use these buttons to select one of two options.
The current state is indicated by the caption of the button: User mode, Yes-No, On-Off.
When you tap one of these buttons, the caption switches to the other function. Confirm this
change by clicking another button (
OK or Save) before the current screen closes.
3. Buttons to enter data. These buttons will be referred to as entry fields throughout this guide.
The caption is either your last entry or <please select>: City, Street, Category (of a POI), etc.
When you tap an entry field, another screen with a software keyboard, a list, or both opens
where you can make entries. Confirm this entry by clicking another button (OK or Save)
before the entry screen closes. Your entry then becomes the caption of the entry field.
IMPORTANT NOTE: When turned on for the first time (or if the unit has been idle for several
days, or been moved more than 250 miles while off), it can take several minutes to acquire a
GPS signal.
GPS signal acquisition times will be typically less than a minute when the unit is turned on
again.
