Reverse Camera not working

[Jughead028]

I have recently bought a stock standard X5 E70 3.5 diesel, 2005 model.

When we first bought the car, the reverse camera would come on whenever we put the car in reverse.

But now, when se put the car into reverse, the GPS map is displayed instead of the rear camera view.

Is this a setting we somehow activated?

Any idea how to fix it?

Cheers,
