Exactly. These systems have been around for a decade and my new phone still works on an old Alpine CarPlay head unit from 2014.
Base alpine software may feel dated, but once the phone is in, I get the modern version of all my mapping, listening, and communication software.
Projection systems rock. I was an early adopter and I refuse to go back. Docking a phone on an air vent is janky.
Have you thought about upgrading to an aftermarket stereo or a one of those CarPlay / aa units that connects to your car’s existing auto inputs? I had CarPlay in a 2001 Subaru.
