Question for sat nav users

Morning all.

Trying to pin down an electrical issue.

May have found a source of this.

Can anyone tell me, when does your day nav unit in the rear box shut up? Mine constantly goes off on its whirling business even after the key is pulled and door is locked.
Noticed yesterday too when it does this random thinking or whatever it's doing, the fan control lights (the green indicator ones) din and go off for a split second. So I'm starting to suspect these are related.

Final questions. Anyone know where the earth points are and has anyone come across this before?
 
I should also add, I no longer have the CD changer plugged in. Oddly the Grom unit has come to life and started working.
When the grom, radio or main CD player is used, if you press the menu button and hit scan (to reset the grom) the sat nav goes bat s**t again.

I hardly use it and would remove it and see what happens however the stereo doesn't function at all without it being plugged in.
