5.1 Switching on for the first time
The GPS Mirror receives signals from the network of 24 satellites orbiting
the Earth, called the Global Positioning System, and uses the latest SiRF
Star III GPS technology to work out where you are every second.
When the GPS Mirror is searching for satellite lock the display will show
“GPS”. Once satellite lock is achieved, a voice alert will confirm “GPS
ready” and your current speed will be displayed. The first time your GPS
Mirror is switched on, it may take up to 20 minutes to calculate its current
position and lock on to the satellites. This is normal and happens with
all GPS-based devices. If you use the GPS Mirror regularly, subsequent
satellite lock will be greatly reduced; normally between 5 seconds and 2
minutes.
5.2 GPS Speedo
The GPS Mirror calculates your vehicle’s speed using GPS data. The speed
reading is continually updated and is extremely accurate when you are
driving at a steady speed. As with all GPS speedo systems there will be a
slight lag during accelerating or decelerating while the GPS data is being
refreshed.
You may notice a slight difference between the GPS speed reading and the
speed displayed by your vehicle’s instruments. This is normal, because car
manufacturers always build in a slight tolerance to their displayed speed
for safety reasons.
The GPS Mirror also has a very handy adjustable “Overspeed Alert”
feature which warns you whenever you drive above your chosen speed
limit setting.
