Only difference from 3 to G4N is the additional plug for nema 2k. The G3N will run the live also. Same processor in both. Only ones that got new processor was the G3 Solix
Thats my understanding also, relieved finally I get to skip a generation. Ive updated my units each time 1,2,3rd gen helix hoping its until 6 that I need to update again!
Curious how their live compares to my garmins.
