I believe that is correct. You only need one GPS module when units are connected via ethernet. My question is why would you want that? There is a natural inaccuracy of these units by about 10'. So if the GPS module is 20' away (stern mounted) from the unit (on the bow) and there is a 10' variability, that means a unit could be 30' off.
I put a GPS module on two units in my boat (bow and stern). That way the most they'll be off is 10'. The GPS module should be associated with the transducer location.
