Raymarine A series charts stuck on imperial... How to change to metric?

[Captain Crisp]

Hi does anyone know how to change these from imperial to metric?
I've searched high and low on 'set up' 'customise' etc, but can't find an option to change the depths shown on the charts to metres...
Is it because my Navionics subscription is out of date?
Thanks,
Crisp

Depends which A series, but if it's the older one :-
Press + hold page/menu button
Scroll down the options until you see units setup (not visible until you have scrolled down a bit)
From units setup choose depth units and you have a choice of metres, feet and fathoms if you fancy a bit of mental maths ?.

Many thanks, I'll try that next time I get to the boat!
