    Canbus stands for something... But basically there are 2 types
    Full and half

    You can tell what you have by the controls on your steering wheel.

    Full = scroll wheels
    Half = 3 buttons on each side of the steering wheel.

    Controller Area Network Bus... Basically everything is computer controlled instead of having switches and wires directly connected stuff...

    Will allow you to control the info screen and change the screen so you can see MPG, Tank range etc etc etc..


    It must do tons more... but im unsure as to what.

    It's not just to do with your info screen etc. It's basically how the modules in the car communicate with each other i.e. the ECU talking to modules like BCM, CIM, DDM, PDM, UEC, REC to name just a few.

    On a full-can car more parts of the car are CanBus controlled so they can do some cleverer things than on a half-CAN car.

    Regarding Tech 2 on a full-Can car, doesn't make it easier as such. Just more options become available on a full-CAN car.
