Automotive navigation system in the context of "Car stereo"

A point of interest (POI) is a specific point location that someone may find useful or interesting. An example is a point on the Earth representing the location of the Eiffel Tower, or a point on Mars representing the location of its highest mountain, Olympus Mons. Most consumers use the term when referring to hotels, campsites, fuel stations or any other categories used in modern automotive navigation systems.

Users of a mobile device can be provided with geolocation and time-aware POI service that recommends geolocations nearby and with a temporal relevance (e.g. POI to special services in a ski resort are available only in winter).

In-car entertainment (ICE) or in-vehicle infotainment (IVI) is a collection of hardware and software in automobiles that provides audio or video entertainment. In-car entertainment originated with vehicle audio systems that consisted of radios and tape cassette or CD players and now includes automotive navigation systems, video players, USB and Bluetooth connectivity, carputers, in-car Internet, and Wi-Fi. Once controlled by simple dashboard knobs and dials, ICE systems can include steering wheel audio controls, handsfree voice control, touch-sensitive preset buttons, and a touchscreen. Some systems have rearview cameras and side cameras for better safety.

Vehicle audio is equipment installed in a car or other vehicle to provide in-car entertainment and information for the occupants. Such systems are popularly known as car stereos. Until the 1950s, it consisted of a simple AM radio. Additions since then have included FM radio (1952), 8-track tape players, Cassette decks, record players, CD players, DVD players, Blu-ray players, navigation systems, Bluetooth telephone integration and audio streaming, and smartphone controllers like CarPlay and Android Auto. Once controlled only from the dashboard with a few buttons, today they can be controlled by steering wheel controls and voice commands.

Initially implemented for listening to music and radio, vehicle audio is now part of car telematics, telecommunications, in-vehicle security, handsfree calling, navigation, and remote diagnostics systems. The same loudspeakers may also be used to minimize road and engine noise with active noise control, or they may be used to augment engine sounds, for example, making a small engine sound bigger. Vehicle audio systems have begun to move to digital platforms utilizing bus networks and optical cables for signal transfer rather than traditional analog cables.

Telematics is an interdisciplinary field encompassing telecommunications, vehicular technologies (road transport, road safety, etc., as part of Intelligent transportation systems), electrical engineering (sensors, instrumentation, wireless communications, etc.), and computer science (multimedia, Internet, etc.). Telematics can involve any of the following:

• The technology of sending, receiving, and storing information using telecommunication devices, such as a Telematic control unit, to control remote objects
• The integrated use of telecommunications and informatics for application in vehicles and to control vehicles on the move
• Global navigation satellite system technology (most commonly GPS) integrated with computers and mobile communications technology in automotive navigation systems, often using a GPS tracking unit
• (Most narrowly) The use of such systems within road vehicles (also called vehicle telematics)
