Part 2. How to Fix iPhone 16 Not Connecting to CarPlay?

So, you've known the possible reasons why this issue happened, below are the key solutions you can try to fix iPhone 16 CarPlay not working issue.

Fix 1. Check Vehicle Compatibility

Make sure your car supports Apple CarPlay and the connection type you're trying (wired or wireless). Since not all cars support new iPhone models immediately, and some older vehicles or head units were designed before newer iPhones (like iPhone 16). You can refer to your car's manual or manufacturer website if unsure.

Fix 2. Inspect Your Cable and Ports

The iPhone 16 uses the USB-C standard. The most common point of failure is using a cable that supports charging but not data transfer. CarPlay relies on a stable, high-quality data connection, not just charging. Even small issues with the cable or ports can completely block CarPlay. So, follow these steps below to check your cable and ports.

Step 1. Swap your current cable for the woven USB-C cable included in your iPhone box, or use a certified high-speed data cable (Thunderbolt/USB 3).

Step 2. Inspect your car's USB ports. Ensure you are plugged into the port specifically marked with a CarPlay or smartphone icon, as some ports are designed only for charging.

Step 3. Clean the USB-C port on your iPhone with a non-conductive tool to ensure no lint is blocking the connection pins.

Fix 3. Reset the CarPlay Connection

Resetting the CarPlay connection can clear corrupted pairing data and connection glitches between the iPhone and the car's infotainment system. Over time, outdated or conflicting settings can prevent CarPlay from launching properly, and resetting forces both devices to establish a fresh, stable connection.

Step 1. On your iPhone, navigate to Settings > General > CarPlay.

Step 2. Select your vehicle from the list and tap "Forget This Car."

Step 3. On your car's infotainment screen, go to the device list and remove/delete your iPhone 16.

Step 4. Next, make sure your car is in pairing mode and go to Settings → General → CarPlay on your iPhone. Select your car from the available devices to reconnect. For wired connections, simply unplug and reinsert the USB cable to re-establish the connection.

Fix 4. Restart Your iPhone 16 and CarPlay System

Restarting your iPhone 16 and the CarPlay system can clear temporary software glitches, frees up system resources, and refreshes the communication between the devices. This simple step often resolves minor bugs or frozen processes that may prevent CarPlay from recognizing your iPhone.

For iPhone 16:

• Press and release the Volume Up button, then the Volume Down button.
• Press and hold the Side button until the Apple logo appears to perform a force restart.

For the CarPlay System:

• Turn off the car completely and wait about 30 seconds.
• Turn the car back on to allow the infotainment system to reboot.

This simple step often restores CarPlay functionality without any complicated adjustments.

Fix 5. Adjust iOS Privacy & Security Settings

CarPlay requires permission to access your iPhone while locked and to communicate with the car. If these settings are restricted, the connection may be blocked, therefore, enabling the necessary permissions ensures CarPlay can launch and function properly.

Step 1: Go to Settings > Siri & Search and verify that "Listen for Siri" is turned on. CarPlay will not function if Siri is disabled.

Step 2: In the same menu, ensure "Allow Siri When Locked" is enabled.

Step 3: Go to Settings > Face ID & Passcode, scroll to the "Allow Access When Locked" section, and toggle on "Accessories." This allows the data port to function while the screen is off.

Step 4: Check Screen Time restrictions by going to Settings > Screen Time > Content & Privacy Restrictions > Allowed Apps & Features and ensuring the toggle for CarPlay is green (On).

Fix 6. Eliminate Network Interference

Wireless CarPlay relies on a stable Bluetooth and Wi-Fi connection. Strong Wi-Fi signals, or electronic interference can disrupt this communication, so reducing interference ensures a smoother and more reliable CarPlay connection.

Step 1: Open your VPN application and disconnect any active sessions.

Step 2: Alternatively, go to Settings > General > VPN &Device Management and ensure the status is "Not Connected."

Step 3: If using Wireless CarPlay, ensure Wi-Fi and Bluetooth are both active in your Control Center.
