There are cars with Nav without parking sensors.
The parking system is only a module that weights a few ounces, the wires that run to the sensors and the sensors themselves. This is pretty much negligible.
The navi + screen is probably ten pounds. Weight of the dash is probably more than the non-navi dash.
But we're talking about a pretty insignificant amount of weight here - not like a CF roof or getting an Akrapovic
