iPhone Connecting to Chigee Display via CarPlay Keeps Disconnecting — Causes & Solutions

If your CarPlay wireless connection drops occasionally, it’s important to understand that the CHIGEE Display itself will not actively disconnect from your iPhone. When a disconnection occurs, it is usually because your iPhone’s Bluetooth or Wi-Fi has actively ended the connection with the CHIGEE Display.
If you can connect successfully at least once, it means the CHIGEE Display is functioning normally. Any disconnection issues are almost always caused by your iPhone’s settings, CarPlay system behavior, or nearby environmental interference.

How CarPlay Connects to CHIGEE

1. Bluetooth Handshake – Your iPhone pairs with the CHIGEE Display to establish a basic connection.
2. Wi-Fi Link – Once paired, Wi-Fi handles high-speed audio, video, and control data.
3. Both Bluetooth and Wi-Fi must remain active on your iPhone for CarPlay to stay connected.

Why Disconnections Happen (Usually on the iPhone Side)

If your CarPlay wireless connection frequently drops, it usually means your iPhone’s Bluetooth or Wi-Fi is actively disconnecting. In most cases, an iPhone that behaves this way will also disconnect from other wireless CarPlay systems.
You can confirm if this is a broader phone-side issue by searching online for your iPhone model + iOS Version + “wireless CarPlay disconnect” — you’ll often find other users reporting similar experiences.
Idea
If your CarPlay drops in the same location repeatedly, it's often caused by external signal interference—such as nearby transmitters, dense Wi-Fi networks, or regional hotspots. These environmental disturbances are rarely fixable via device settings. 

Step-by-Step Troubleshooting

Follow these steps in order to fix frequent disconnections:

Step 1: Verify Your Connection History

Has CarPlay worked with your CHIGEE display before?
  1. If yes: Something recently changed in your phone(an update, new app, setting). Upgrading to a new iOS system or CarPlay version often causes disconnections. Please contact Apple Support for confirmation and solutions.
  2. If no: It may be a setup issue—double-check compatibility and walkthrough.

Step 2: Check for Interference from Other Bluetooth Devices

Make sure your phone is not connected to other Bluetooth devices like smartwatches, BMW TFT displays, or smart home systems. These can interfere with the CHIGEE connection.
Instructions:
  1. Open Bluetooth Settings on your iPhone.
  2. Forget or unpair any connected devices such as smartwatches or BMW TFT
  3. Restart your phone
  4. Reconnect only to CHIGEE and Carplay stability

Step 3: Disable Smart Device Controller Apps

Apps such as Samsung SmartThings or similar smart home controllers may disrupt CarPlay’s wireless connection.
  • Disable or uninstall these apps if possible.
  • Restart your iPhone.
  • In CarPlay settings, make sure these apps are not enabled for use in CarPlay.

Step 4: Optimize Wireless CarPlay

  • Go to Settings > Wi-Fi > CHIGEE-XXXX and:
    • Turn off Limit IP Address Tracking.
    • Turn off Private Wi-Fi Address.
  • Go to Settings > Wi-Fi:
    • Ask to Join Networks → set to Off (instead of Notify).
    • Auto-Join Hotspot → set to Never (instead of Automatic).
  • Go to Settings > Cellular:
    • Disable Wi-Fi Assist.
  • Go to Settings > Personal Hotspot:
    • Enable Maximize Compatibility.

Step 5: Check iPhone Settings

  1. Allow CarPlay While Locked
    • Go to Settings > General > CarPlay > Your Car
    • Enable “Allow CarPlay While Locked”
  2. Disable Low Power Mode
    • Go to Settings > Battery > Low Power Mode
    • Turn it off (Low Power Mode can limit background connections)
  3. Disable Your VPN
    • VPNs can interfere with the CarPlay connection.
    • Temporarily disable your VPN to test stability.
  4. Turn Off Do Not Disturb While Driving
    • Go to Settings > Focus > Driving
    • Make sure it is off, as it may interrupt CarPlay functions.

Step 6: Reset Network Settings & Restart Your iPhone

Resetting your iPhone’s network settings clears outdated configurations or incorrect connection data that may interfere with CarPlay.
From our experience, frequent CarPlay disconnections are often caused by Wi-Fi or Bluetooth channels being occupied by other connections. Resetting helps remove these conflicts and restores default network settings.
How to reset: navigate to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings

Step 7: Forget and Reconnect All Cars on CarPlay

Your iPhone can store CarPlay profiles for multiple vehicles, and old records can sometimes cause connection conflicts.
Go to Settings > General > CarPlay and remove every listed vehicle by tapping each one and selecting Forget This Car.
After clearing all previous records, reconnect your CHIGEE Display wirelessly and test if CarPlay remains stable.

Step 7: Complete Reset Process (If issues persist)

On your CHIGEE Display:
  • Go to Settings > Reset and perform a full system reset.
On your iPhone:
  1. Go to Settings > Bluetooth and forget all CHIGEE-related Bluetooth devices.
  2. Go to Settings > General > CarPlay and remove all entries.
  3. Turn off Wi-Fi completely (disconnect from any active Wi-Fi networks).
  4. Reconnect Bluetooth to CHIGEE and tap:
    • “Pair”
    • “Allow”
    • “Turn on WLAN & Connect”
    ⚠️ Important: Do NOT tap “Use Bluetooth Only”
  5. Restart your iPhone.
  6. Try reconnecting to your CHIGEE Display again.

iOS-Specific Tips

  • Ensure your iPhone is running the latest version of iOS.
  • If possible, test with another iPhone model to rule out device-specific issues.
