I only use the set that I made. When there is more then one type, like a McDonalds next to a gas station, it will show the triple icon instead of one or both of them or it will group some on the horizon. Just added "use_multi_poi_icon=0" in the sys.txt for primo 1.2 to stop grouping them but it doesn't work in in primo 2.0.
If different poi's are set to display on the map and they are close to each other then igo groups them together and displays them as a triple generic icon.
In igo8 up to primo 1.2 it was easy to disable.
I'm asking if anybody here knows the code to do that in primo 2.0.
Of course if I choose only one poi to display like Shell gas station it wouldn't do that unless there was two Shell stations next to each other. Then it would group them in the triple balloon.
The only thing that I can tell you is to greatly limit the number of categories that are visible. Until something is known in the 2.4 sys.txt this is the only that I can think of presently. The only other suggestion would be to go back to igo8.
