Hi, does anyone have a photo of SZL module circuit board with multifunction steering wheel buttons?
I want to add multifunction steering wheel buttons to my SZL and I think its not that hard, just need to solder pins and in addition needs few capacitors or resistors, but I dont know its values, I hope to find those from photos. This is my SZL module with missing sport and pins soldered:

Anyone knows how to find out those few missing components?
Other than that multifunction steering wheel should work.

Good thing photos exist on internet:

So its:
6040 = 604ohm
103 = 10000ohm (need to re-solder from one place to another)
capacitor = not sure the which one, just used similar colors and size as in the photo

I tested and I am getting CAN BUS message "1D6: FFF3", if no buttons connected, once I connect buttons I get "1D6: C000".
Does anyone know why I don't get "1D6: C00C"?
Am I still missing any components on the board?
