That bulge at the front is the Eaton Vorad forward radar antenna. I had the same option on my HR Navigator although in my rig the antenna was flush mounted. It provides the cruise control a distance regulation to vehicles ahead and also a closing alarm if approaching too fast.
On my rig there is also one smaller antenna each side for sideways detection turn signal alert if there is a car alongside when you indicate. I assume #776 would also have the same smaller antennae on the sides as well.
