I can’t find CarPlay on my iPhone se Is it possible it was deleted?

Update your iPhone to iOS 14.4.2, and pair or re-pair your iPhone with a vehicle with CarPlay system, and you should see CarPlay available on the vehicle entertainment system. CarPlay is not something you look for on your iPhone. What few settings are available (once paired) are in Settings > CarPlay. If you do not see CarPlay, confirm with the vehicle dealer that the vehicle offers the CarPlay feature, and then that you have the current firmware loaded for the entertainment system.

There's not much you change for CarPlay from your phone.

What are you trying to do?
