Dear texas
I do not like favorites on the map display as well
In my installation of iGO_PAL this issue was solved by erasing the line
@Favourites||500000|500000
in the file data.zip\ui_nextgen\defaults\poi_visiblities.txt
and then erasing the 4 files
poi_visiblities_A.txt
poi_visiblities_A.txt.cks
poi_visiblities_B.txt
poi_visiblities_B.txt.cks
from the directory iGO_PAL\save\profiles\01

I hope that helps you
