AM Garmin sat nav, quick question..

[Xarig]

I can't work out how to change the volume on the Garmin in my Vantage, she's rather loud! Can anyone help please.

It's a woman - they're all loud

There's a trick to it!
Turn the volume knob only when she is making an annoucement

Has anyone found a way to easily mute the instructions without going in to setting and turning it off?
