What's This? Mystery switch

[MilesandSmiles]

I've looked in all the manuals that came with my 2004 Southwind, but I can't find an explanation for this switch with the music notes on it. Anyone know?

Okay so that's not a typical on/off switch?

It allows you to play the radio without turning on the ignition switch while parked. Be careful, it can run down your starting battery.

Three choices..

1: Radio power.. Up is either chassis or house, down is the other
2: Aux horn (optional)
3: Silences an alarm (Probability very very very very low).

Be careful, it may bring out the dancing girls.

That's a good idea. I'd like to install one of those. I wonder how they do that without backfeeding everything else on that circuit?

Thanks! I knew someone would be able to solve the mystery.

Yup it's for the radio...
