Pajero Owners Club of South Africa

I have an after market CD player, and my electronic display still showed the compass, date and air on controls. After having my battery run down, I am no longer able to see the air on controls on the display. Everything else seems to operate normally.

Does anyone have a suggestion where I can start trouble shooting?

I removed the air on control unit, cleaned it out and checked all the internal connections (internal ribbon) and reconnected.
All sorted ....
