audio problems

[03 G35 sedan]

i have an 03 G35. I am having problems with the radio controls and screen display. and also the air controls. i can control radio,cd, from steering wheel only. Button controls and screen on dash do not work. Also air button controls do not work or control air. the top screen is working but cant be adjusted due to the control buttons not functioning from dash. ive checked the fuses and not sure where to go from here? any ideas????

Maybe a connector from the control module came loose. Look at the FSM and take the control bezel off and reconnect to see if that helps.
