I owned a 2018 Tundra and recently installed a vivid 2k 13.3" 4g+64g head unit with a CB004. Everthing is working good except for the steering wheel control function is not working. I have double check all the connections and tried to map the steering wheel keys on the radio setup but no responds on the the screen when I pressed the steering wheel buttons. Let me know how to fix this issue.
Thank You
