Too bad I didn't know about this before I got a Kenwood DNX-693S. However, to be fair, I'd probably still have purchased the Kenwood. We plan to take roadtrips to and through areas that don't have cellular reception, thus rendering Maps useless; the Kenwood has a Garmin GPS system that just needs a GPS signal to function. We will be using the Garmin system for those portions of those trips and Maps the rest of the time because the UI is just so much better and it integrates with my calendar.
So far I have been happy with it and 90% of the time I'm using CarPlay, so the UI isn't a problem... but for the times when I want to listen to radio (it does have HD capability, including subchannels), I really don't like the built-in UI much. I'm hoping Kenwood will improve it in the future, but I'm doubtful.
I specifically chose a non-nav-equipped second-generation (2008-2012) Ford Escape when purchasing a used vehicle. I wanted something that would accept a double-DIN CarPlay unit (Crutchfield will sell you the panel you need along with the radio) and I like the boxy styling and the practicality of it.
It's perfect for what I need in a vehicle right now and it's got lots of nice-to-have things like dual-zone temperature control (some family members like their cars hotter than I do; this eliminates fights when they ride with me), a rear view camera (which displays in the rear view mirror, though I could have routed that to the head unit), moonroof, auto headlights, and it can accept a block heater and there's aftermarket projector headlights to be had for it that I'll be fitting with LEDs for better night visibility.
It really is a shame that it's getting harder and harder to install an aftermarket navigation/radio, but at least the factory ones are getting better (slowly) and CarPlay/Android Auto support are becoming more and more common.
