Struggling with getting this to function the way I expected. Two main problems; (1) I can't delete the volume bar that keeps appearing no matter which screen is open, and (2) there seems to be no option on navigation other than showing coordinates and a world map. I understand there is an actual map file - I can't figure out how to access it. There is an option to buy a point to point feature; no mention of this when I bought the system. Any help appreciated. Thanks.
