There are several potential causes for your problem. This is not an issue you have to live with though intermittent problems are harder to find the core cause. I suggest troubleshooting the easy stuff first--don't start throwing parts at the problem.

Since it is intermittent I would first troubleshoot for airbag leak. Easiest to do.
Clues an airbag is leaking:
The light comes on shortly after you begin driving and it is after it has been sitting for several hours or overnight. You can see the X has settled in one or more corners. When you examine the airbags they not completely smooth or have cracks. The compressor keeps running or starts and stops frequently.

Are there particular circumstances that happen that causes the light to come on or go off?

I have no idea how your nav screen is connected to the air suspension issue unless the problem is electrical. BMWs are very sensitive to out of spec voltage. How old is your battery and alternator.
