Garmin 12XL Help

Anyone have some knowledge of this unit? My mate has one and it won't switch the screen on, but does make beeping noises as if it is alive in some way.

Anyone know the sequence of button-presses to do a master reset, please?

Turn it off.

Hold down 'Mark' and turn it on.

Job done
