How To Grant Permission To Use CarPlay While iPhone Screen Is Locked

When CarPlay first launched it worked on any iPhone running iOS 7.1 or later. One limitation was your iPhone's screen had to be unlocked in order for CarPlay to work. Apple did away with that with the release of iOS 8.3 back in April.

If you connect an iPhone with iOS 8.3 or later to a CarPlay-capable head unit or car, you will be prompted to allow permission to use CarPlay while the phone is locked. Click 'Allow' and you should be good to go.

What if you clicked 'Not Now' but later on feel that unlocking the iPhone to use CarPlay can get disruptive? There is a way you can change you permissions through 'Settings'. Here are a couple of other things to keep in mind.

CarPlay Permissions in iOS

Personally, I was delighted when Apple allowed the use of CarPlay without having to unlock the phone. When you get into your car and plug in your iPhone to your head unit or dashboard, you should be able to use CarPlay right away. Requiring drivers to unlock their iPhones after turning on their vehicles could be a safety issue.

With the iOS 8.3 release in April, Apple added a CarPlay option in Settings on your iPhone which allows you to toggle permissions for use while the device is locked. This is where you find it...

On your iPhone click on Settings ---> General ---> CarPlay. Here you will find a list of head units or cars that you've used with your iPhone in the past. Click the '(i)' next to the appropriate option and you will be shown this screen where you can toggle ON/OFF the permission to allow CarPlay while locked...

List of CarPlay Devices

As you can see in the screenshots above, iOS saves a list of all head units or cars you've ever used CarPlay with on your iPhone. You can choose to forget a head unit or car by clicking on the 'Forget This Car' option. This removes the device from the list just like in Bluetooth settings. The next time you connect to that device your iPhone will prompt you to allow permissions by throwing this pop-up on your screen...

Unnamed Devices

The issue I have with the list of devices is the way some head units, in my case the Pioneer AVH-4100NEX (listed as 'AV Receiver') and the Pioneer AppRadio 4 SPH-DA120 (listed as 'Display Unit') do not show the correct model number. The Kenwood DDX9702S shows up correctly. This is probably something Pioneer needs to address.

With the wide range of CarPlay devices I test, the list on my iPhone keeps getting long. When I don't have access to a particular head unit anymore, I just forget the device and remove it to keep my list short. This may not be an issue for consumers though.
