Dash air vent, how to remove please

[Ukrobotman]

Hi folks , I’m replacing my dash top storage box with an Oem part that’s a tray I can fit my sat nav to.
I worked out how to remove the speaker grill in the dash but I can’t work out how to remove the heating grill below the dash storage box.
Can anyone enlighten me ?

Looking at the pic of the unit above I’d say the trim around it comes off and the vent is held in with screws.
Could be wrong as I’m just guessing by looking at the vent in your pic.
