Not for nothing but I thought this might be relevant: in my aging Subaru, the aftermarket Bluetooth FM receiver and CD slot-mounted phone holder that I recently installed (and reviewed earlier) have both been remarkably seamless and effective.
As soon as I am in the car, my phone automatically pairs. The sound quality is good and the pairing consistent. And when mounted in the phone holder, the setup is about as convenient as having an OEM touch screen. I have been very, very impressed.
For the longest time I was convinced I needed (ok, wanted) to trade my car in for something newer because I craved and infotainment upgrade (yes, even as an enthusiast). It seemed so frivolous as the rest of the car has been running so well and at odds with its likely current trade-in value. But now I see the aftermarket infotainment tech has really caught up and there are now excellent solutions.
TL;DR: I realize I'm preaching to the choir here, but if we are correct that consumers are increasingly prioritizing infotainment availability in their car purchases, they really need to explore the aftermarket solutions (mine cost $45) for their current rides before they dump tens of thousands of dollars on a new one, just for the pleasure of asking Siri to "play Taylor Swift 1989, track 2" (I'm not a fan, I swear, GF is)
