Farewell paper mapLong live the GPS! In recent years, navigation systems have made their entry into force in the passenger cars, relegating the big road atlas at the bottom of glove boxes, to make way for a bright color screen interactive. There are three types of GPS:
Embedded systems.
They are fully dedicated to the automobile. There are two kinds: car stereos browsers, no more bulky than a conventional car (size 1-Din) and those equipped with a retractable screen. Very expensive (from 699 Euros), the former can be used in the vehicle where they were raised, but it is more efficient.
Nomads
From the world of boating and hiking, they represent over 90% of sales. Two advantages: reduced cost and the possibility of being transferred from one vehicle to another. The mapping is already pre-loaded on a memory card or a hard disk drive. Although they are often delivered with internal GPS antenna, it is recommended for best reception of GPS signals, buy an optional external antenna if your car has a heat reflective windscreens.
PDA and Smartphone
In recent years become an extension of the mobile office, calendar and address book, PDAs are now offering navigation. An interesting alternative to the nomads, but for safety reasons, must remain off in the car. Because their interface is not intended for automotive use. In addition, their processor is generally less efficient, so the route calculation is much slower.
