A Brief Introduction of Can Bus

“CAN-bus is a vehicle bus standard designed to allow microcontrollers and devices to communicate with each
other within a vehicle without a host computer.”, quoted from wiki.
For the car dvd unit, it needs the can bus to get the original information work, such as used for transmission,
airbags, antilock braking, audio system, windows, doors and so on. As well as the main function to generate the
steering wheel control work after we replace the car dvd player to the cd player, and to make the original lcd or
the car information working as original. Check the samples below:
Here is the car dvd player for mazda 3. it needs can bus:

you can find the external can bus box in the accessories box. Don’t worry about inside or external box, they are
the same. The importance is that we need to use can bus no matter inside or external box for some cars, or we
will lose some of the original function like steering wheel control.
