Product safety & precautions
Thank you for purchasing the Street Guardian SGGPSAD
Auxiliary Display
The Auxiliary Display is designed to operate best at
temperatures of between -20c to +70c, operating outside
of these temperatures may produce unpredictable results
and should be avoided.
Clean only with a soft dry cloth, being careful not to use
excessive pressure, the use of liquids or cleaning fluids may
damage the product and could void your warranty.
The Auxiliary Display is suitable for 12-volt systems only
and must only be used with the included connection
cables.
Do not attempt to use the cables to connect to other
devices as it could cause damage, do not attempt to use
other cables to power the Auxiliary Display.

Installation & configuration
Choose a suitable mounting location where the unit is easy
to see and cables can be routed without causing any
interference with the operation of the vehicle. Use the
appropriate mounting option to suit your vehicle, rubber
sticky pad or Velcro adhesive, ensure that the cables have
enough clearance to avoid damage and any excess cable is
cable tied or routed so as not to interfere with the driving
position.
The basic features are pre-configured with logical default
settings and are supplied ready to use once installed with a
minimum of adjustment needed to personalise to your
needs.
If using in a vehicle with an ignition switched power source
it is only necessary to set the time offset, all other defaults
are preset. If the vehicle only has a permanent power
source it will be necessary to configure the power off time
and sleep voltage menu settings so that it will power off
when not in use. It is important to make sure the device
has access to GPS signal to work correctly.

Gps overview
When the SGGPSAD is first powered on it will begin looking
for satellite signals, if the SGGPSAD has not been used for
several hours the time setting will revert to the selected
offset value when there is no GPS signal, once signal has
been detected the clock will update, once this has
happened the GPS will begin negotiating the connection.
It takes three satellites to triangulate your position, the
GPS will increase accuracy as more satellites are locked
and will often lock onto 7 or more satellites at once, each
satellite provides its own position information and
instructions to the receiver known as Ephemeris data, the
download of this information takes 12.5 minutes (if it all
comes down error free, otherwise it starts again), this data
provides accurate forecast position information valid for
the following few hours but only for that particular
satellite, there is also Almanac data which is much less
accurate but valid for much longer periods and for all
satellites, obviously you typically get a signal much faster
than 12.5 minutes and some basic triangulation and
positioning info can be provided relatively quickly in some
circumstances depending in the state of the GPS, cold,
warm or hot.
10
There are three distinct modes for the GPS, Cold start,
Warm start and Hot start,
A cold start is when the GPS has been off for more than 4
hours and this process must begin from scratch each time
based on Almanac data of roughly where the Satellites
might be.
A warm start is around 30 minutes, if the GPS had signal
within 30 minutes prior to a restart then the Ephemeris
data collected is still valid and the GPS has an idea which
Satellites to look for and reasonably close to where they
should be at the time, the warm start is generally quite
quick in comparison to a cold start.
A hot start is when you have a signal already and you drive
out of coverage, through a tunnel, under a bridge or
similar, when you come back into a coverage area the GPS
knows what Satellites you were connected to and will look
straight back to those same ones and will pick the signal
back up very quickly.
