I strongly suggest that you, please, allow the 'honk' to reveal all bodies in the system map - but only as pictures of the bodies on the map and add them, with distances, as "Unexplored", in the navigation panel.
Then one could use the FSS, if sufficiently interested by the system map/nav panel reveals, to use the FSS on the bodies to actually 'discover' them.
