"Its bad enough that cars with the "old" iPhone dock connector are now permanently obsolete"

They need something like ISO 7736 which about thirty years ago was formerly known under some now obsolete DIN standard, so naturally 30 years later we still call it single or double DIN mount.

I'd be happy with a secondary ODB-II port for charging and read only access. The physical side of car audio is pretty standard via the ISO standard aka "DIN mounts", but the electrical side is eternally messed up with embrace-extend-extinguish every decade another fad connector.
