yup! me too. Thats how i ended up buying a new car instead of a recent second-hand version of the same. Carplay was an absolute non-negotiable must have.
With a large screen capable of CarPlay with enough real estate for navigation etc? Most everything is custom OEM sizing/fit/etc these days , gone are the days of interchangeable single-cd headunits
Custom OEM size/fit has been addressed to some degree for a quite a while now by both the "mainstream" car audio manufacturers [1] and, more extensively, by some lesser-known aftermarket brands [2].
YMMV based on just how old your car is and the type of OEM head unit, but there are kits (e.g. this one for a 2016+ Honda Civic [3]) that allow you to install "standard" head units with a fit/style similar to OEM.
Yes, I was considering replacing my 2013 Honda Fit but just got a double-height Pioneer radio (AVH-2400NEX iirc) installed by an audio dealer.
It works perfectly, kept the existing car controls and I still have a car that mysteriously fits your entire apartment inside it while also not being subjected to a CVT.
