I've got a TT Digiflight II VSG (GPSS but no GPSV) connected via a switch to a GRT Horizon and a GNS 480. I've been driving the AP directly from the 480 which works great for lateral guidance and altitude hold. I can't really see the benefit of switching the AP to use the EFIS as the input.
Am I missing something? Since the AP doesn't have GPSV, are there any benefits to letting the EFIS drive the AP?
