I bought a Honda Accord in 2019 and it comes with CarPlay integration in
the centre console. The centre console is controlled by the Honda
system in the console and they integrate Apple Play.
The apps that will play there are limited by Apple to very specific apps:
https://www.apple.com/ca/ios/carplay/ (Canada page).
In different countries this list is different for some things.
IMO the most useful thing is navigation.
I typically use Apple Maps for local use and Google Maps for longer
trips where planning stops is more important. In both cases the
planning can take place on my desktop computer and sent to my phone. In
the car, voice commands can be used, but recognizing some names (esp. in
French) is not guaranteed at all.
I'd use Waze more but I dislike its visual presentation.
For music I use voice commands. Going through the menus via the car
console is tedious and would actually be dangerous unless parked. This
doesn't work well if trying to get to a particular album of classical
music but for rock/jazz is usually spot on. To advance a track or scan
forward the steering wheel controls are used.
Phone is integrated too, of course, and uses the car's audio system.
The Honda system itself integrates the phone and CarPlay integrates the
phone. It's still not clear to me if that's two paths to the phone or
whether CarPlay and Honda's phone implementation are coordinated. In
any event it doesn't matter - it works well either way. Siri sometimes
won't understand who it is I want to call.
Messages is by voice - (I believe one can select destinee via the
console but I never do that while driving) so Siri sometimes doesn't
recognize a name that I want to send messages too. I don't do that
often enough that it's a big deal and if it's urgent I can phone or pull
off the road to do so.
That's what I typically use. There's more available such as podcasts
and so on. It's a pretty short list.
Depending on car model, the above is wireless or not. In my case it's
wired which is fine. I've installed a short Apple USB lightning cable
from under the armrest and it's the perfect length to get to the
cupholder position. No tangles that would occur with a longer cord.
I suspect the coming years will see ever better integration of
smartphones and cars. The upcoming iOS will have the ability to unlock
and start some cars. Indeed you'll be able to temporarily "credential"
another person to use your car using his iPhone - no keys needed. And
set limits on what he/she can do with it (speed, time limits, perhaps
geofencing, etc.) while knowing where the car is at all times. "Yes,
son, you can take the Bimmer on your date - on my terms!".
If your car has a HUD then some CarPlay info can be displayed on it -
I'm not sure. I seem to recall reading where some cars support Apple
CarPlay controlling some info on the primary driver's display.
I keep the iPhone in a coffee cup holder type mount and on it I display
"hidden" engine parameters such as actual coolant temperatures,
wastegate position and manifold pressure. (via Bluetooth from an OBD-II
reader (BluDriver)) - it can record a mountain of data too.
I'd like it if there were more backward integration: data from the car
sent to the iPhone for recording. Mileage, realtime speed and fuel
consumption data, temperatures (OAT, coolant) all position tagged. If
all this (and much more could be recorded in CSV files, it would be
nifty for my nerd side.
Closing note: I've always despised automobile manufacturer's map
displays. They're always very short of the mark in their designs, very
expensive, expensive for updates and so on. The marriage of nice
displays (which are Android based for the most part) and allowing one to
choose his info/nav system of choice is a beautiful hybrid.
