When I remove Fuse #72 (Audio/Nav) in the cargo area my battery drainage stops, but then I dont have radio or cd, I do have Navigation but no audio/sound.
I replaced the "Audio Unit Relay" (cargo area) but still get battery draining when fuse#72 is in place? Help?

Please see link for fuse and relay:
