Next, check the volume controller bubble that will appear on the display, similar to the one on your iPhone.

2. Reconnect the Apple CarPlay

You can re-establish a connection with the CarPlay stereo through the “Bluetooth” settings on your iOS device.

A potential fault or congestion of the signal may lead to audio issues or cause persistent interruptions.

Here’s how to reconnect your iOS mobile from the CarPlay stereo easily:

  1. Open the “Settings” app on your iOS device.
  2. Scroll down and enter the “General” section.
  3. Tap on “CarPlay” to access the vehicle page.
  4. Locate the connection of your current vehicle.
  5. Tap on the connection of your car to manage.
  6. In the vehicle menu, tap on “Forget This Car.”
  7. Confirm the pop-up by pressing on “Forget.”
  8. Wait until your phone rediscovers the vehicle.

Shortly after unpairing the vehicle’s Bluetooth, all nearby CarPlay-enabled stereos will be rediscovered by your mobile and will appear in the CarPlay menu.

Note: Forgetting the vehicle’s CarPlay connection will not remove the Bluetooth profile!

3. Re-add the Main Unit’s Profile

After establishing a wireless connection, the Bluetooth profile of the CarPlay-enabled FM radio will be assigned to your iOS device’s settings.

Well, an improperly configured radio profile may cause issues with the audio or result in re-occurring signal interruptions.

Follow these instructions to re-add the radio’s Bluetooth profile:

  3. Next, scroll down and locate the CarPlay profile.
  4. Press on the “Info” button next to the connection.
  5. Next, scroll down and tap on “Forget this Device.”
  6. Wait 30 seconds and re-discover the stereo unit.
Warning: All custom Bluetooth stereo settings will be erased after forgetting the profile!

4. Set Up a Wired FM Connection

Even if the Apple CarPlay connected but no sound via Bluetooth, you should test setting up the FM radio’s profile through a wired connection.

Based on the type of your CarPlay stereo and iPhone model, you must either use a lightning cable or USB-C to establish the connection.

  • Only the iPhone 15 and iPhone 15 Pro use a USB-C cable, so you will require a standard lightning cable for all of the previous models.

Once you have the cable, connect the USB 2.0 with the CarPlay and plug the other end with the iOS mobile.

Note: The audio of the mobile should be automatically transferred to the multimedia!

5. Update the Mobile’s iOS Version

The CarPlay may not function properly or connect with your mobile if the iOS firmware version is outdated.

So, the next step is to upload the latest iOS firmware available for your device through the “Software Update” tab in the settings.
