Dash light dimmer most likely!! Got the owners manual? Turn it does anything happen? Did you just get this vehicle? You tell us when you find out what it does.
it actually is a radar detector volume on off switch!!!
Cool, not familiar with them, illegal here in Va. They got to wright them tickets i guess!
