GVIF transmits uncompressed serial data at speeds up to 1.95 Gbit/s. GVIF transmits over a single
differential pair, as a result, the cable is thin. Transmission distances up to ten meters are possible.
Utilisation
The GVIF bus was used circa 2000 onwards on many mid range vehicles including
Land Rover Discovery 3
Land, also known as dry land, ground, or earth, is the solid terrestrial surface of the planet Earth that is not submerged by the ocean or other bodies of water. It makes up 29% of Earth's surface and includes the continents and various isla ...

Range Rover ,
Lexus Models and
Toyota Prius. The GVIF bus was primarily for carrying the video signal between the integrated
Satellite Navigation unit and the in vehicle display (also known as Head Unit). GVIF bus in these vehicles only carried video despite the specification allowing for data stuffing of other information.
