My 2012MY car has Bluetooth, but only for calls/interruptions not for music so I've been using USB sticks still. It has a navigation system but the map DVDs are so weirdly expensive that I have never updated the maps. I'm at the point where I don't always trust the nav system to get me somewhere and use my phone. I leave the car's map up if I want to glance at it to double check, but also assume some of the roads are wrong now. The biggest thing I miss is "next turn info" in the driver cluster, but the Apple Watch has a version of that. It's still less convenient to glance at my watch instead of the driver cluster, but still better than glancing at my phone or having to mount my phone somewhere.

CarPlay sounds fantastic but right now all the manufacturers I'm looking at for "next car" don't support it. I keep thinking if I never experience it first hand I'll not be disappointed if the "next car" doesn't have it. Bluetooth for music might be enough of an upgrade for me. It seems interesting to me this pendulum swing in "every car has CarPlay" to "manufacturers don't trust CarPlay" has happened within the time period of me owning a single car. It probably says something about the car life cycle.
