I have a 2018 Tundra and recently installed the vivid 2k 13.3 4g+65g head unit /w the CB004. Everything is working good except for the steering wheeling function is not working. I have make double checked all the connections and also I tried to map the steering wheel keys on the radio but no responds on the screen when I press the steering wheel buttons. What can I do to resolve this problem?
Thank you
