Not sure how this could possibly be more expensive in hardware either though, we're talking about one antenna versus two GIAs, an MFD, and four servos.
My understanding is that you don’t need to change the GIAs. I have never seen different GIA reference with or without GFC 700, so I assume they are the same units

I think you're right but when upgrading to GFC700 from KAP140 (the majority has GIA63) I would expect replacing GIA with GIA63W (or GIA64W which requires changing GDU to NXi). However GIA's are separately priced.

And GWX 70 that I have installed in my NXi DA62 is also now obsolete; newer unit is GWX 75 with a wider field of view (sweep angle). But GWX 75 isn’t certified in our planes with NXi.
Having owned planes with all three radars, I'd say the 70 was a nice step up from the 68. It paints weather with much less noise so it's easier to tell what's real, particularly around mountainous terrain. That's also the big advantage of being able to overlay it over the terrain map. The 75 takes some getting used to and for Diamond altitudes, probably not that much of an improvement. I like it in the M600 because it's so sensitive that you can dial up the gain and spot turbulence a little better. I don't have the terrain suppression on the 75. Apparently for the low low price of $13,000 I could unlock the feature but that strikes me as outrageously expensive for something that supposedly doesn't work that well.
