Carputer

A carputer, or car-puter, is a computer with specializations to run in a car, such as compact size, low power requirement, and some customized components.

[1] The first carputer was introduced by Clarion on December 4, 1998,[2] although on-board diagnostics have been employed since the 1980s to precisely measure the amount of fuel entering the engine as the carburetors got too complex.

[1] Police cars often have Mobile data terminals in the form of a laptop swivel mounted where the driver's armrest would be.

[12]  They can be used for watching movies or listening to music, as well as for GPS navigation, and also have Bluetooth for hands-free calls.

[13] Computers can be used to decode on-board diagnostics (OBD) data to a visual display.
