Radio/NAV On Board Monitor knob/buttons do not work

[ArmyX5]

Guys,

I need help here. I have searched the Forum to see if anybody had this problem before and I found one thread, but the guy never updated it. My problem started about two hours ago on my way home from work. I started the car and I try to change radio station, but nothing happened. I pressed the rest of buttons, but the only one that worked was the right side knob on the monitor. I can control the zoom on the map and I can press the phone button and it will send the signal to my phone. My NAV and radio work and I can control the radio from the steering wheel, but that's about it. I have tried to reset the vehicle by disconnecting the battery, but still the same. I checked all the fuses and they are all good. I don't know what else to do other than to take the Nav monitor apart and see if the cables inside are somehow lose. I wanted to see if anybody had the same issue and how they fixed it before I take that step. I have done it before and prefer not to do it again.
