Yo DD So far it appears the only way to clear the map is to engage a new "list", which I have done. There may not be an option to hide an item on the map without removing or deleting it from the list. I can work around it. With the Mac it is click and drag to add info to a list or you can copy and paste. Still monkeying around. I would very much be interested in smaller icons as these seem a bit bulky to me. I have noticed several empty boxes in the basecamp icon selection and am wondering if these are for custom icons. Quite likely.

One way of "clearing" waypoints (and thus their icons) from the screen is to create a series of categories into which waypoints are placed.  There are over a dozen generic categories that you can code to be whatever you want.  To view the current list of categories, select EDIT from the menu and PREFERENCES from the pop-up list.  Then look for the Waypoint Categories tab.  You might choose to make the categories something like campsites, portages, pictographs, POI's, wildlife sightings, etc.  In other words, whatever set of categories may sense to you.  Then you can change the waypoint property of individual waypoints to one of the created categories.  Once that's done, you can select a specific category to be displayed (category selection toward the top of the left panel).

To scale down the icons, you can create custom icons (or perhaps find some you can download from the internet).  You should be thinking of a size that is 16 X 16 pixels to get to the "small" category.  I have some that are 6 X 6.  The next step is to find where the Custom Icons have been stored on your computer when you loaded the software.  For a Windows based system this is generally under My Documents in the My Garmin folder.  The last step is to replace the pre-existing custom icons (numbered from 000 - 007 in the Custom Waypoint Symbols folder with your own.  If the new symbol is not already in bmp file format, they should be converted to that format with a graphic editor program.  Once you've done that, you will see the new icons appear at the bottom of the available icons list when you create a new waypoint.  To change an existing icon, you simply change its icon property.

BTW:  You can change the properties (category, icon) of several icons at the same time if you select a group of waypoints and then edit the waypoint property of that group.  (For a Windows based system, you can select an item by clicking on it, a contiguous group by pressing the SHIFT key and dragging over a set of waypoints, or non-contiguous items by pressing the CTRL key and then making a series of individual selections.)
