I'm not yet instrument rated, and I wont have to make this decision for at least a year, but there's no harm in thinking about this now. Also, I'm referring to Garmin for this question simply out of familiarity, but I'm not settled on them.
I'm just starting building and I'm leaning toward a fairly minimal one G3X-based glass panel. I like the idea of the GNX 375 (Navigator+ADS-B transponder), which does not have VHF NAV (VOR/ILS). Basically, with the exception of maintaining currency, I see myself doing GPS IFR exclusively. If there is a GPS outage in IMC conditions, I likely just won't want to fly.
Adding VHF NAV to my idea of an ideal panel is at least a $3,500 investment (GTR 200 to GNC 255A, much more if going with the GTN 650Xi, because then I need a seperate ADS-B transponder). Seems a lot to maintain currency for a mode of IFR flying I don't intend to do. Instead, I'd just rent from a local club, or find a buddy.
So the real question: Is there some other rationale that I should consider that might convince me to fork out thousands more $$$ to add VHF NAV?
