On my dash, the switch with the music note switches radio power from ignition to house batteries. It's a two way switch. The lightning bolt starts and stops the generator. The battery icon is a momentary on switch to connect house and chassis batteries (boost switch) I agree with the dome and heated mirror guess, I don't recognize the 4 bladed fan with the coil. I'd think perhaps defroster fan, but on mine it's part of the heat/air control panel. Turn on the ignition and start flipping them and look for reactions.
