don''t know about the G3X, but I have one hooked to a skyview system and it works just like that. select the freq on the dynon and it sends it to the radio. the dynon sends it to the standby in the V16 and I have to push the knob on the razor to put it in the active window, but that is also how the dynon radios work with skyview. the V16 uses the SL-30 protocol and works just like the SL-30 does,now. I might have been the first to use a V16 with the skyview and found there was a bug in the software on certain freqs. a couple of emails to later a patch appeared in my inbox and on their web page and it workes perfect. I really like the radio and will probably add a N16 to my plane.
