  • 4. Change and savePress and release mute to switch between On and Off. Leave the controls alone for about 7 seconds until Settings Saved shows, then turn the ignition off.

No volume and mute buttons on the steering wheel? Mid City's guides above show the turn signal stalk method.

If the module loses power (unplugged, or the battery is disconnected or goes flat), the settings go back to the factory defaults and have to be set again.
