HI!!!
First of all it should be prepared by this element, it is an i-bus interface, it's when you've got the rest of the info you can send a simple switching.



 

The radio 9 (i-bus) must be connected to GND + intrfacet a computer course.
I attach a progit to handle the i-bust. If it tied the radio progin the machine set to the port where good Aradia off switch and sends a message 2 (power supplies only if you do you can also send messages to the radio), then any message sent back to the radio and there it goes. In case if you take the power off the radio will be asked again. If you do write to the car in front you have a knack for it. If you were able to write.
Click on the bottom of the message, then Send key is turned on but the radio.
