How Do I Navigate With Gps - Mio C728 User Manual

How do I navigate with GPS?

The Global Positioning System (GPS) is available at any time, free of charge, and is accurate within 5m (15ft). GPS
navigation is made possible by a network of satellites that orbit the Earth at around 20,200km (12,552mi). Each satellite
transmits a range of signals which are utilized by GPS receivers, such as your Mio, to determine an exact location.
Although a GPS receiver can detect signals from up to 12 satellites at any time, only four signals are required to provide
a position or "GPS fix" (latitude and longitude), for vehicle navigation systems.
How does my Mio receive GPS signals?
Your Mio receives GPS signals via the internal GPS antenna. To guarantee the optimum GPS signal strength, ensure
your Mio is outdoors, or in a vehicle outdoors, and has an unobstructed view of the sky. GPS reception is not usually
affected by weather, however, very heavy rain or snow may have a negative effect on your reception.
How do I view my GPS status?
You can view your GPS status at any time from the map screens or the GPS status screen. displays green
when a GPS fix is established and red when a GPS fix is unavailable. To indicate the reception strength of a GPS fix,
displays between one and four green vertical bars.
Note: Before you begin, check if your vehicle is fitted with a heat-reflective or heated windscreen. If so, you may need to purchase an
external antenna for your Mio to receive GPS signals. The first time you use your Mio, it may take up to 15 minutes to establish a GPS
connection.
To view your GPS status in more detail, see "GPS Status".
