Of course, north up is the only reasonable setting while sea navigation and all other maps are disabled in the marine profile of my Oregon.

But it is absolutely impractical when in some zoom levels the satellite images not disappeared. I often had situations, where I speedy had to zoom out for better overview and if there are only dark satellite images, where nothing to identify, it could be dangerous.

Did you tested some new (v11.50) maps on your GPSmap62s? On Oregon it is now possible to deaktivate the second part of the map, so that only the nautical map is visible. So are these new G2V maps are also good usable on Oregon/Dakota/Colorado.
