Hi!

Yes, you can use your iPhone SE 2020 for Apple wireless carplay in your Mazda CX-5. To set up Apple wireless carplay on your Mazda CX-5, you need to turn on WiFi and Bluetooth on your iPhone. Then select "Apps" from the main menu in your Mazda CX-5. Scroll down and select "Apple carplay". Select "Add new device". Then on your iPhone, go to "Settings" and then "Bluetooth". Select the name of your vehicle (which is usually "Mazda") in the Bluetooth discovery list of your iPhone.

I hope I helped you!
