New vehicles come with some features that weren’t available on your Dad’s Buick. Some of them may be a bit confusing or hard to understand. Consumer Guide has a glossary of automotive terms that might be helpful. If you have any questions please give us a call at Mike’s Auto Repair (714)375-3145
Navigation System
An electronic map combined with route instructions, usually displayed on a dashboard video screen. The system communicates with a satellite to display, on the screen, the vehicle’s geographic location and direction of travel. Most systems let you input a destination using a keypad. A computer then calculates the best route and issues audible and visual directions to reach that destination. A few navigation systems lack a map, but provide vocal instructions. Some new systems operate with voice recognition, and are able to “understand” addresses and other oral instructions. Navigation systems are usually optional, though some luxury models have them as standard equipment.
Overhead-Cam Engine
In this configuration, the camshaft that drives the valve is located atop the engine rather than down inside. Engines with a dual-overhead-cam configuration have two separate camshafts rather than one.
