There are two icons on the left to show the
status of the GPS connection and the qual-
ity of reception.
GPS Connection Indic ator
In the middle to the left there is a lamp
similar to the ones used for switches. This
one has more colors and represent s more
values:
• A fast blinking green lamp means that
there is communication with the GPS and
data is being received,
• Other colors may not appear with a bui lt-
in GPS. Should any of these appear, this
means a faulty operation of your device.
GPS Data Quality Ind icator
In the top left corner there is a satellite dis h
to show the quality of the GPS position.
Different colors represen t different signal
quality:
• black with a red cross means there is
no connection with the GPS device. This
should ne ver be th e case if your devi ce has
a built-in GPS.
• red means the GPS is connected but no
GPS position is available,
• yellow means 2D reception. A GPS posi-
tion has been acquired, Cydle is ready for
navigation, but the GPS is using enough
satellites for calculating the horizonta l po-
sition only. Elevation data is not provided,
and the position error may be signifi cant.
• green means 3D reception. The GPS re-
ceiver has enough sate llites to calculate
altitude. Position is generally corre ct (yet
it can still be inaccurate due to different
environmental factors). Cydle is ready for
navigation.
Time Synchronization
In the top right corner of the screen you have
another button that leads to a new screen
where you can synchronize the clock of
your VRVD640G to the very accurate time
provided by the connected GPS.
Turn on the Auto Correction switch to let
Cydle frequently check and correc t the
VRVD640G time with the GPS time.
Below that button you will see the cur-
rent values of the GPS and the VRVD640G
clocks. You can check here whether any
correction is needed. Touch the button to
manually synchronize the time.
Below the VRVD640G time you have hour
and minute controls to man ually cor-
rect the time with or without a valid GPS
time. It also gives you the chance to cor-
rect the time after synchronization if your
VRVD640G does not support tim e zones or
daylight saving time.
The Map
The most important and most fre quently
used screens of Cydle are the two scree ns
with the map (Map screen and Cockpit
screen). They are similar in look, but are
optimised for different uses. The m ap they
display is common.
TIP: You may move the map by pressing
the screen and dragging your fi nger across
the screen. The map will move in the direc-
tion of your fi nger.
Map Controls and Functi ons
The maps look similar to paper roadmaps
(when using daytime colors and 2D map
mode). However, Cydle provides m uch
more than regular paper maps can. The
look and the contents can be changed.
