CarPlay and Android Auto Issues

CC4 Pro keeps disconnecting from an iPhone hotspot

Check whether the head unit loses its Wi-Fi connection to the hotspot, or whether only CarPlay disconnects. If possible, test the hotspot with a second device.
If only the CC4 Pro drops off, forget the hotspot on the head unit and reconnect. Record the iPhone and head-unit software versions if it keeps happening.
A static IP on the head unit was reported to help in one setup. Ask support to confirm the correct network settings for your setup before trying it.

Start with your model and connection mode

Record the exact unit and supported connection method. Compare native Bluetooth calls/media with projection calls/media, then note whether the fault affects wired connection, wireless connection or both. Use the correct installed projection app for the unit; do not substitute an APK from an unrelated model. A successful manual reconnection is a partial result if automatic reconnection still fails.

The legacy Carlink and F-port checks below apply only where those components are specified for your unit. CC4-family menus and apps may differ. Use your model’s guide rather than copying older settings.

Back up before any factory reset; model-specific firmware and reset steps should come after basic connection checks.

NOTE: If it was working before but after updating the firmware it stopped, Simply forget the head unti from your phone settings and repair again.

Step 1: Make sure that the F port is connected. This has important Bluetooth and Wifi connections that CarPlay utilises.

Step 2: Make sure your 5G wifi antenna is connected

Step 3: With CarPlay, connect wirelessly first. Some users have reported that when pairing via USB first, stops the phone from connecting wirelessly.

Step 4: Only use the Carlink app pre-installed with the unit. Do not use the CarPlay settings on your iPhone.

Step 5: Make sure that the bluetooth module is registering.

Step 6: Use a known-working data cable suited to your phone, whether Lightning or USB-C, and the USB connection specified for CarPlay or Android Auto on your unit. Charging alone does not confirm that the cable or port carries data. Try another data cable. Check the connection method supported by your exact TEYES model before buying an adapter.

Step 7: Make sure you are running the latest firmware

Step 8: If support recommends a reset for your model, back up stored data and settings before performing a factory reset

Lately there has been a spike in CarPlay not working. We believe this is related to iOS.

Reports of updating to the latest iOS has resolved this issue.

Problem:- Android auto suddenly stopped working – can’t play music or do voice control via Android Auto

Solution - Update the google apps to have android auto on the phone updated again.

NOTE: Some people have complained that when a call is recieved during carplay it is in full screen. Simply press the bottom red square to exit the call screen if you need to go back to a different screen.

Problem: Some users have reported that when google maps announces directions it cuts the music off instead of lowering the volume.

Solution: Factory reseting has been reported to solve the issue

Problem: Some users may experience issues with Bluetooth audio handoff—specifically when switching between voice input, phone calls, and media playback. After a voice prompt or call ends, the media volume level may change unexpectedly, resulting in inconsistent loudness.

Solution: If this happens, go into your iOS settings for bluetooth connection and select "other"

LUX One: factory radio works but Android audio is silent

If your LUX One installation sends Android audio through the original vehicle’s AUX input, select AUX in the original vehicle audio menu. This has resolved the symptom in a recorded support case. If your kit uses a different audio connection, follow its installation guide or ask support to confirm the correct source before changing wiring.
