Montana 700i any way to remove controls icons on main map screen?

I found where you can move the control icons to the left or right side of the screen but I would like to hide them altogether. I want it to operate like the dashboard setting where it is hidden with a little arrow that expands out when you need it. The icons take up about 5% of the screen real estate, which is not a ton, but I would like 100% of the screen showing the map, not 95%.

Thanks!
