Cameras & recordingReverse camera problems and TEYES app activation
Check your exact model first
Identify the exact unit and application. If refresh fails or a locked screen prevents it, contact support privately with purchase details and an error screenshot. An activation error alone does not establish theft or counterfeit hardware.
The older reference below applies only where its model, hardware and symptoms match your installation. Confirm applicability with support before wiring, firmware, parts replacement or reset steps. Back up before any reset or storage format.
If you get these notifications on your reverse Cam REC app, TEYES Vision app and TEYES DVR app, simply connect the unit to the internet and press the refresh icon on the app screen. This is protected software that belongs to TEYES, as long as your unit is genuine and not stolen, it will be activated following this process.

Cameras & recordingI have a 360 system and the image looks like this
Striped or distorted image after replacing a 360 camera
Mixing 720p and 1080p cameras in the same 360 system causes the striped distortion shown below. All four cameras must match the resolution specified for your kit.
Before ordering a replacement camera, check the resolution of the camera you’re replacing. Look for the 1080P label on the camera lead, as shown below. If the label is missing or unclear, confirm the resolution with TEYES Support before ordering.
Other 360 camera faults
This is caused by connecting a camera to the F port. This is not compatible with the 360 system, if you want to use a 5th monitoring camera, install on the A port harness video input and view via the AUX app
Below is an example of what can happen if not all 360 cameras are installed.

Sound & callsCarPlay microphone is quiet, has feedback or does not work
Check your exact model first
If Bluetooth calls are clear but CarPlay calls are quiet, silent or echo, record unit, phone, app and software versions. A microphone replacement or noise-reduction setting is not a confirmed cure for every model.
The older reference below applies only where its model, hardware and symptoms match your installation. Confirm applicability with support before wiring, firmware, parts replacement or reset steps. Back up before any reset or storage format.
Situation 1: My microphone sounds bad while using Apple Carplay. I sound very quiet / there is feedback where the caller hears themself.
Situation 2: I have problems with the external mic when connected to car play.
I have turned the internal mic off. The mic won’t work when the wifi is off and connected to car play. I have changed the settings for the wifi to stay on but it still doesn’t. So when I make a phone call no one can hear me.
When connected to just Bluetooth the mic works. Just seems to be when carplay is connected
The Carlink app for CarPlay is using the internal mic of the iPhone and the head unit for noise reduction, this is not optimal. Disable it by opening the Carlink app while bluetooth is disconnected (to give you more time to go into settings without the iPhone connecting).
Select NO for noise reduction.
Sound & callsThere's a difference in sound between using Bluetooth audio and the audio directly from the head unit.
Check your exact model first
For silent phone audio, record which sources work: FM, native apps, direct Bluetooth, CarPlay and Android Auto. Pairing alone does not confirm the audio path. Test modes separately while parked.
The older reference below applies only where its model, hardware and symptoms match your installation. Confirm applicability with support before wiring, firmware, parts replacement or reset steps. Back up before any reset or storage format.
Go to settings --> Factory settings --> 168 --> Volume Balance settings and adjust accordingly to your preferences
NOTE: this does not control NAVI volume and other in-app volume controls. It only allows mixing.
If bluetooth call volume is too low, you can adjust the power conditioner. See here
Sound & callsOn my CC3 2K I can connect to bluetooth and play music but if I am trying to play voice messages like on Whatsapp, I cannot hear anything.
Set your bluetooth settings to "Bluetooth Music"
Sound & callsThird-party apps have low volume or no subwoofer output
Only the music from the TEYES apps sound good and uses the subwoofer. Instead any other app that plays music or videos doesn't sound right and is lower in volume or use subwoofer.
You must turn the bluetooth source up to maximum. In case of your phone turn it up to maximum. Activate the 5.1 in the equaliser to get the subwoofer working.
NOTE: Music volume and caller volume can be 2 different settings when using your phone so you must check them in your phone settings.
Firmware & setupWhen someone calls, the default level is 16 and its very loud during carplay
Re-pair the connection between the phone and head unit
Sound & callsMy subwoofer is not working properly
Activate the 5.1 in the equaliser settings
Cameras & recordingAfter I installed the firmware, the reverse image is not showing when in reverse but live view functioning.
Check your exact model first
Manual video and automatic reverse activation are separate checks. Record the working app/input and whether reverse changes the screen. Do not install another firmware variant based on another customer’s case.
The older reference below applies only where its model, hardware and symptoms match your installation. Confirm applicability with support before wiring, firmware, parts replacement or reset steps. Back up before any reset or storage format.
Reinstall the firmware to rectify.
Sound & callsAudio balance shifts to the left when using USB or YouTube
Sound balancing - when I listen to radio app the sound is normal, but when I play fro USB or YouTube the sound balance shifts to the left.
Perform a factory reset: Settings --> User --> Backup/Reset --> 168 --> Clear all data
Update to the latest firmware after if required (here)
Sound & callsMy aftermarket amplifier has 2 inputs (left and right) for subwoofer, but the 5.1 L port harness has one green sub-out. How do I connect?
You will need to use a AV splitter
Vehicle controlsWhenever I drive over ~ 130KM/H or 80mph, a voice announces that I’ve been speeding and to drive safe. How do I turn this off?
Go to Settings --> User --> Driving Reminder --> from there you will have options for speeding reminder and fatigue driving reminder that you can enable or disable.
Vehicle controlsMy door graphics and A/C display used to work but now it is not showing
Check your exact model first
Distinguish absent overlay, stale readings, wrong units and physical climate-control failure. Record what original controls still do. An icon appearing does not prove complete climate operation.
The older reference below applies only where its model, hardware and symptoms match your installation. Confirm applicability with support before wiring, firmware, parts replacement or reset steps. Back up before any reset or storage format.
1) Check here for a/c and door options
2) Double check your canbus settings
4) Go to Settings - System - About Device - Check if the canbus is being registered under CAN Protocol Version line, or if it is showing as Unknown. If Unknown, check your canbus connection on the harness and also to the C port for any lose connections.
3) If the above is ok do a factory reset
Power & startupThe unit performs a full boot every time the ignition is turned on
Power Issues
The unit does a full boot instead of quick boot every time the accessories is turned on. The Accessories G3 and Main battery power G2 are swapped around so that G2 is coming on with ignition and G3 is always on.
G1= 0VDC NEGATIVE
G2= 12VDC ACCESSORIES POWER (Swapped with G3)
G3= 12VDC MAIN BATTERY (Swapped with G2
Correct Vehicle Voltage condition on these pins when ignition is ON should be as follows:
G1= 0VDC NEGATIVE
G2= 12VDC MAIN BATTERY
G3= 12VDC ACCESSORIES POWER
Correct Vehicle Voltage condition on these pins when ignition is OFF should be as follows:
G1= 0VDC NEGATIVE
G2= 12VDC MAIN BATTERY
G3= 0VDC ACCESSORIES POWER
Power & startupThe unit only comes on when the reset pin is pushed and held in and the optical light on the back comes on when the ignition is on.
The accessories G3 is missing 12VDC. You have the following condition which needs to be fixed.
Check for blown fuses, wire misalignment from factory pin to G plug or if the G3 accessories is only supplied by canbus (not all cases), the canbus could be faulty by not outputting 12VDC even if it has G2 main battery supply to it.
G1= 0VDC NEGATIVE
G2= 12VDC MAIN BATTERY
G3= 0VDC ACCESSORIES POWER
Below is an example of a symptom of 0VDC on G3 Accessories input
Power & startupThe fuse is blowing when the unit is connected, then the Negative G1 and Main Battery G2 are swapped
Please note: The unit has a 15A fuse, some vehicles accessories are lower than this and can blow. You may need to either upgrade the accessories fuse for your vehicle if it's safe to do so, or run a new accessories line.
G1= 12VDC MAIN BATTERY
G2= 0VDC NEGATIVE
G3= 12VDC ACCESSORIES POWER
Power & startupThe unit turns off as expected by the battery is draining.
Check your exact model first
Distinguish a lit screen, repeated waking and battery drain with the screen off. Have an installer check ignition-on and ignition-off supplies using the model-specific guide. Do not apply a universal CAN supply rewire or increase fuse rating from this symptom alone.
The older reference below applies only where its model, hardware and symptoms match your installation. Confirm applicability with support before wiring, firmware, parts replacement or reset steps. Back up before any reset or storage format.
Sometimes in some systems, the canbus (if installed) keeps something "awake" in the engine bay which drains the battery.
The solution is to disconnect the G2 mains battery supply to the canbus, and power it by G3 accessories power only so that the canbus also turns off when the unit is off.
NOTE: If the G3 only comes from the canbus only, then you will be required to run your own accessories power to the main power supply to the canbus instead.
IMPORTANT: some installations with this issue have been identified as having the reverse camera incorrectly installed to the main battery G2 instead of the accessories. This will cause the camera to stay on all the time and drain the battery.
Power & startupWhen I crank the key from accessory to ignition, the HU screen goes black for 1-2 seconds and then comes back. Is this normal?
Power & startupMy unit is not fast booting from start
Check in your Factory settings if you have Sleep Mode selected ON
In general settings, set sleep delay to 3 seconds.
Firmware & setupMy USB port / ports are not working.
Check your exact model first
Charging confirms power, not a working USB data connection. Compare a suitable data cable and device on the specified port, then compare direct supplied leads with retained factory USB connections. A voltage reading alone does not establish data operation.
The older reference below applies only where its model, hardware and symptoms match your installation. Confirm applicability with support before wiring, firmware, parts replacement or reset steps. Back up before any reset or storage format.
- Check the connection for Port D (USB1) and E (USB2/3) and make sure they are pushed all the way in and seated correctly.
- Check the USB1 & USB2/3 cables for any damaged cables or loose wires.
- Check that the socket D and E pins are not bent or damaged
- Measure the voltage on pins 1 to 3 on socket D and E for 5VDC
- If you measure 5VDC then it is fine
- If no voltage if found on these pins, try to perform a factory reset Settings - User - Backup/reset - 168 - clear all data
- Unplug the canbus wait 5 minutes and plug it back in again.
- If still no success, send back for warranty repair
NOTE: If not using the supplied USB cables direct to the unit and instead using retention to the vehicles original USB port, this might not be compatible.

Connectivity & GPSMy GPS stopped working, how can I fix it?
Check your exact model first
Use your exact model’s GPS guide. An antenna replacement failing to help does not establish a defective head unit. Record the signal symptom and each test result before further parts or firmware changes.
The older reference below applies only where its model, hardware and symptoms match your installation. Confirm applicability with support before wiring, firmware, parts replacement or reset steps. Back up before any reset or storage format.
1) Check that the SMA connection at the rear of the head unit is not loose
2) Check for any cabling damage
3) Swipe the screen down and select "Reboot"
4) If that does not work, perform a factory reset
Settings --> User --> Backup/Reset --> 168 --> Clear All Data
5) If each of those steps do not resolve the problem, replace the GPS dongle

Cameras & recordingDVR starts recording, then stops after a few minutes
For the TEYES DVR used with CC3, CC3 2K, CC2 Plus, CC3L and LUX One, the maximum microSD card capacity is 32GB. This limit applies to the DVR, not to separate 360 recording storage.
Some customers reported that replacing the card restored recording. Those reports do not change the supported 32GB maximum or prove that storage causes every recording fault.
Use a card of 32GB or less for these models. Save any recordings you need before formatting or replacing storage. A flashing indicator alone does not prove that a usable recording was saved. For other models or recorders, confirm the applicable limit with support.

Vehicle controlsThe climate icon stopped opening after an update (CC3 / GX470)
Reported setup: CC3 in a 2005 Lexus GX470; physical A/C buttons still worked, but the on-screen controls would not open.
Evidence: Customer-confirmed outcome in one installation; not a guaranteed repair.
The customer reported that opening Vehicle Information through Settings → Apps launched the climate controls and restored the icon. A factory reset had not restored it.
For a matching CC3 setup, check whether this application is present and can be opened.
Limits: This restored the climate interface in that installation. It did not repair the separate CarLink problem, and it is not a fix for non-working physical A/C.
Sound & callsDigital microphone connection problem: check the exact A-port harness
The digital microphone works only with the CC4 Pro. All other TEYES head units use analogue external microphones. For the CC4 Pro, check the microphone installation, then select the external microphone in settings.
Reported setup: CC4 Pro in a 2018 Suzuki Jimny JB74; supplied digital-microphone connection did not match the available harness.
Evidence: Customer-confirmed outcome in one installation; not a guaranteed repair.
Support supplied a replacement CC4 Pro A-port harness. The customer explicitly reported that the system and SIM connection then worked.
Ask support to identify the correct harness for your unit before ordering or changing connections.
Limits: The exact harness revision is not recorded. This does not prove every microphone or SIM fault is caused by a harness, or establish an analogue adapter solution.
Vehicle controlsTPMS stops reporting after changing seasonal wheel sets
Reported setup: Reported with two TPMS sensor sets and a receiver retained from the other seasonal set.
Evidence: Customer-confirmed outcome in one installation; not a guaranteed repair.
The customer confirmed the problem was resolved and explained the receiver/set mix-up after changing wheels.
Check that the receiver belongs with the sensor set currently fitted. If the set cannot be identified, ask support before replacing or re-pairing parts.
Limits: The report does not provide an exact receiver model or pairing sequence. It is not evidence that all TPMS kits use the same receiver or pairing method.
Vehicle controlsLUX One controls still fail after setup: replacement cable-set outcome
Reported setup: LUX One in a 2015 Ford Focus; settings changes and a reboot had not restored the reported controls.
Evidence: Customer-confirmed outcome in one installation; not a guaranteed repair.
After support investigated the cable set, the customer received and installed replacement cables, then explicitly reported everything working correctly.
Send support the unit, vehicle and supplied cable details so the exact kit can be checked.
Limits: This confirms the reported replacement outcome, not a universal Focus harness defect. The cable part/revision and faulty circuit are not recorded.
Sound & callsExternal microphone remains unusable after settings checks (CC3 2K)
Reported setup: CC3 2K in a 2015 Honda CR-Z; microphone troubleshooting and CarPlay noise-reduction changes had not resolved the issue.
Evidence: Customer-confirmed outcome in one installation; not a guaranteed repair.
The customer explicitly reported that replacing the microphone harness fixed the problem.

Display & appsCC4 Pro will not fit the supplied Fiesta frame: replacement-frame outcome
Reported setup: CC4 Pro in a 2011 Ford Fiesta; the originally supplied frame interfered with fit.
Evidence: Customer-confirmed outcome in one installation; not a guaranteed repair.
The customer received a replacement frame and confirmed that the CC4 Pro fitted directly, without lowering its motherboard or moving screws.
Ask support to verify the frame and unit combination before trimming the dashboard or altering the head unit.
Limits: The exact replacement-frame part number is not recorded. Direct fit in this installation does not establish fit for every Fiesta, screen or kit.
