Hello guys,
I'm new to the forum because I've been searching for weeks on how to communicate with the I-bus of my 2003 BMW.
I found this forum through Google and was hoping some of you would be able to help me.
What I want to do:
I have a navigation unit (OEM) in my car which has several buttons. I would like to duplicate some of the switches to my steering wheel. So that when I press these new buttons, they perform the exact same action as the original button on the navigation Unit.
I know which codes are linked to the buttons, but I don't know how to add a new button and to let it send it's code.
I hope anyone can help me with this.
Thanks in advance

Hi,
I'd imagine that you'd find more people knowing about BMW buttons in a BMW forum - this is after all a robotics forum, so it's like asking how to build a robot on a car forum.

Guys on any BMW forum don't know the answer.
I just asked my question here because it isn't BMW specific. I just need to find a solution to make a switch execute an action by sending a code through I-bus.
Maybe you guys know any chip that can send programmed Ibus signals when a button is pushed...

Have you been able to find any information about the I-Bus?
