What is GPS?
The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 32 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.
What kinds of information can the GPS receiver provide for us?
After GPS receiver receives the signals, it could provide latitude/longitude, speed and direction.
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".
What is POI?
POI stands for point of interest.
These are categories such as restaurants, hotels, gas stations, etc.
What is a map update?
You can find update information from menu: Setup--System--System Informatıon. Follow the web site for the map updates.
When does the recalculation occur?
A recalculation occurs due to a traffic information update, or when you have detoured from the initially planned route.
Why is the GPS location not detected when I turn the device on?
Please note that a GPS receiver must be locked on to the signal of at least 3 satellites to calculate a 2D position (latitude and longitude) and track movement. The quality of the GPS signal can be affected if:
1. The user is the city with the high buildings around him.
2. The user is in a tunnel, under a viaduct or indoors.
3. If the user takes the GPS receiver in the car. Some heat-insulation films will affect the quality of the GPS signal.
