It's not s***, it's just overpriced.
No, not yet, although plenty of retrofit kits exist. I'd take Apple/Android over HUD any day though. My Z06 had it, and I rarely used it.
I'll jump in on this one, as I currently own a '18 CX-9, and have previously owned Jeep Grand Cherokee's. When I was shopping for my CX-9 I purposefully shopped the GC as well. And I think you're wrong about the comparisons. The only thing my CX-9 does not have as far as options is concerned is the "signature" package. When I priced similarly equipped current model Jeep GC's, the price was over $10k more for the same options list. If you think the CX-9 is overpriced, you should price out a similarly equipped jeep...there is no comparison cost wise. Also note that when I was shopping, the CX-9 was barely over MSRP, even for the well equipped models!
Also, drive the current models of both. The new GC drives much, much better than the old ones (gotta give credit where it's due), but it still does not drive (i.e. turn as well, feel as balanced, inspire as much confidence when pushing it, ride as smooth, make you smile) as well as the current CX-9. Again, no comparison.
Then there's that pesky issue of the third row seating, which was a requirement for me.
The new jeeps are nice, and if I were to buy a car for going off-road regularly...it'd be a jeep. But for my use, seating for seven, all the amenities the CX-9 has at it's pricepoint, the GC doesn't come close.
