I remember from VV2 that it was possible to use the map to spot collectibles after a certain level of tech was obtained. I've tried to do this in VV3, but either it doesn't work the same way, or I've just not caught them.
I have the game completed except for the collectibles, and it sure would be easier to watch the map rather than make myself dizzy with flyovers!

If this has been covered before I apologize. I did do a search for 'map" and came up empty.
