B．解题分析：利用“navigation satellites”作为答案线索，这样在文章中找到答案相关句：
Before starting out on a trip, a driver can type in the code for the region he or she plans to drive through. The computer then shows a map of that region. At the same time, a tiny radio receiver linked to the computer goes to work. It picks up signals from navigation satellites such as the NAVSTAR network. Using these signals, the computer shows a the car’s position at all times and displays this position on the map. The computer can also calculate and display the best route to follow. 来源：考试大
A navigation computer may also receive and use data about road construction, weather conditions, and traffic jams. This information would be displayed to the driver and the computer would also use the information to work out alternate (交替的) routes.
Most cars nowadays also contain computers that help cars run more efficiently. Microprocessors (微处理机的) control certain engine functions by regulating the mixing of fuel. Data on car speed, oil pressure, revolutions per minute, engine temperature, and fuel level can be displayed as digital data (numbers) or warming lights.
