The Global Positioning
System (GPS) is a satellite-based navigation system made
up of a network of 24 satellites placed into orbit by
the U.S. Department of Defense. GPS was originally
intended for military applications, but in the 1980s,
the government made the system available for civilian
use. GPS works in any weather conditions,
anywhere in the world, 24 hours a day. There are no
subscription fees or setup charges to use GPS.

Why can't my GPS device determine my
current position?
For a GPS receiver to
calculate one's longitude and latitude (considered a 2D
'fix'), the receiver has to be able to receive confirmed
data from at least three satellites. Some conditions may
interfere with receiving this data.
A. In a city, tall buildings may block one's view of
satellites.
B. When driving through a tunnel, or when standing
indoors, the structure overhead may block or reduce
strength of received signals.
C. Some cars use a type of heat-insulating film on the
windows which may also affect reception of satellite
signals.

Can my Mio GPS device receive satellite
signals indoors?
Yes¡Kand No. Satellite signals can penetrate some
building materials though with lower signal strength
than through open air. In some buildings it is possible
to get a strong 3D satellite signal lock, though it may
take longer than when outdoors.
¡@
What kinds of information that the GPS
receiver can provide for us ?
After GPS receiver receives the signals, it could
provide latitude*/longitude*, height*, speed* and
direction*, and determine the user£¾s position* on the
map.

What is TMC, and why do I
want it?
TMC stands for Traffic Message Channel, and is an FM
Radio broadcast of real-time traffic information. Data
messages are received silently and decoded by a TMC
receiver buit into the navigation system or external
cradle. Several Mio DigiWalker navigation devices
support traffic and can re-route you around the traffic
incidents.
¡@
What is TTS?
TTS stands for Text-to-speech which will say the names
of the streets or exits you need to take. For example,
with TTS OFF you would hear ¡§In 300 yards turn left¡¨,
while with TTS ON you would hear ¡§In 300 yards turn left
on 1st Street. The TTS voice in Mio device is named
Samantha, and is the default voice.
¡@
How can I locate a lost or stolen Mio
GPS?
Although the device can track its position, it does not
transmit that location. It cannot be located by an
outside source, such as the Police, LowJack or by Mio
Technology.
¡@
What is POI?
POI stands for point of interest. These are yellow pages
listings for categories such as restaurants, hotels, gas
stations, etc. Millions of POIs are preinstalled in the
Mio device.

What is a map update?
A map update usually includes the latest maps available
for your device, as well as some minor software
improvements. For some areas where coverage was already
near complete [ ex: most US metro areas] the main
improvements will be re-verified map data and refreshed
points of interest. In other areas where there was a lot
of growth in the past 1-3 years [ex: Las Vegas, Phoenix,
etc.] or where coverage was less than complete [ex:
parts of some Canada provinces] map updates will show a
lot of new streets and you¡¦ll be able to navigate to new
addresses or new points of interest.
