FREQUENTLY ASKED QUESTIONS
GPS navigation systems require a clear line of sight to work effectively and will not work indoors.
Function may also be impeded in heavily wooded areas and city streets between high rise buildings
that may impede line of sight to satellites.
In conjunction with the map software loaded on to the GPS unit, the system can calculate your exact
location, heading, speed and correct time and overlay the results on a map of the area. The software
in the system can also calculate the best route to other locations and give instructions to the driver
on the best route giving fair warning of impending turns. These warnings can be given visually or
audibly depending on the model of the system. Different models can have a wide variety of
functions and features.
Q: How accurate are GPS systems?
A:
In perfect conditions, GPS navigation systems are generally accurate to 3mtrs. Several factors can
impede the accuracy of the GPS unit. These include atmospheric conditions, signal reflection (or
multipath) and clock errors. Most of these errors are small and are usually only apparent when
stationary. Typically a personal GPS unit is accurate to within 15 meters.
The GPS system is only as accurate as the mapping software in the unit. If the map data is incorrect
the visual representation of you location may not be displayed correctly.
Map data is compiled from several sources and may not be 100% up to date. Councils and regulatory
authorities may change road signs, add or remove traffic lights and roundabouts and change the
direction of traffic along roads at any time and these changes may not have been made at the time
the mapping software was complied.
Q: Why does my Navig8r receiver show that I am moving when I am standing still?
A:
Occasionally, GPS satellites may broadcast a signal error called Selective Availability (SA). This can
be displayed as up to 4KPH of movement on the GPS receiver.
Q: The GPS unit will not turn on after charging. What can I do to get it working again?
A:
In most cases this problem is easy to resolve. Make sure that the GPS is charged or connected to
a power supply. Remove the Mount Cover form the rear of the device and locate the reset button.
Using the supplied stylus, press the reset button. The GPS unit should now start and load the main
menu. You will need to reset any settings such as the system time and date again.
If the above does not work and the system will not start, please contact the reseller or tech support
