Cannot get it to work with UNO and proper CAN BUS cards... is it because the following during the send
Try to update two lines in config section:
#define CAN_SPEED CAN_125KBPS // Entertainment CAN bus - Low speed
#define CAN_FREQ MCP_16MHZ // Switch to 8MHZ if you have a 8Mhz module

I have BSI2004 car (Citroen C5 X7) and try to install NAC from P508. Previosiy I had SMEG+iv2. I have bought Chinese plug adapter, but when I try to lauch NAC in my car through this adapter there is only black screen. I know that NAC unit is fine, as I can test it in another P508. I do not fully understand where to connect 2 lines of CAN that should go to the screen. With SMEG screen CAN lines are sourced from PINs A11 and A14. Where should I connect screen CAN when NAC is installed? I have tried to split CAN going to NAC unit (A10/A13) and connect it to screen. It was wrong idea as car was getting a lot of errors on CAN bus
If it's possible, can you share your final code, or send it to me -
