Features and menu options vary by model and hardware version. Check the model named in each answer; older CC3 guidance may not apply to the CC4 range.
Models & softwareIs the CC3 2K checkout upgrade a replacement screen?
No. The checkout upgrade is an option for a qualifying new CC3 order, not a separately shipped replacement screen. If you already own a unit, use the replacement-screen listing and have support check your exact model, screen size and frame. Changing only the display does not replace the processor, Bluetooth hardware or cooling design.
CarPlay & connectivityDoes a USB port charging my phone prove its data connection works?
No. Charging confirms power is present, but it does not confirm a working data connection. Check the specified port and a suitable data cable for your exact unit. Tell support whether the problem affects one device, one cable or every USB device.
Settings & passwordsDoes selecting a language guarantee voice control in that language?
The system interface and voice-control application are separate. Check the supported languages for your exact unit and voice application before ordering. If a selected language still produces another language, send support the unit model, app name, version and a screenshot of the language selection.
Audio & microphonesCan I keep front-to-rear fading with an amplifier that has only two inputs?
A stereo input provides left and right channels, not separate front and rear channels. Do not assume an RCA splitter will retain independent front-to-rear fading. Have your installer check the head unit outputs and amplifier inputs before choosing a connection method.
Cameras & accessoriesWhy do reverse guidelines appear but the camera picture is black?
For a black reverse-camera picture, check the camera connection and correct camera-format setting for your unit. Follow our reverse-camera troubleshooting guide for checks matching your symptoms.
Cameras & accessoriesWhy does my DVR stop recording even after a software update?
Follow our TEYES DVR installation and fault-finding guide, including its memory-card checks if recording stops or the app freezes. Save recordings you need before formatting a card.
Models & softwareMy USB firmware update is not detected or fails verification. What should I check?
Follow the firmware update guide for your exact model. Use the CC3 / LUX One guide for those units and the separate CC4 guide for the CC4 range.
Cameras & accessoriesWhat should I do if my CC4 Pro 360 activation code is rejected?
Contact support privately with your purchase reference, exact unit model, software version and a clear photo of the error. Support may need to check your activation card and device details. Do not post your activation code or serial number in the forum.
Models & softwareCan I move my TEYES head unit to another vehicle?
Ask support to check the destination vehicle and the exact head unit before reusing the installation kit. The fascia screen size, vehicle harness, CAN interface and adapters for factory equipment may differ, even where the head unit itself can be reused. Provide pictures of the central dashboard, details of the vehicle’s year, trim and original audio system.
Models & softwareWhy does my unit only start while I hold the reset button?
This is a symptom of the accessories power input on G3 not receiving 12 V DC. Have your installer check the supply using our power-testing guide.
Cameras & accessoriesDoes a blank 360 camera view mean the head unit needs replacing?
Follow our reverse-camera troubleshooting guide. It includes checks for 360 cameras going blank, including isolating the cameras and their cables.
Support & warrantyWhat information should I send technical support?
Include the exact model, vehicle year and trim, original audio equipment, software version and a short description of the fault. Explain when it occurs, what still works and what each attempted check changed. Send original-dashboard and connector photos where relevant. Share purchase references, serials and activation details only through private support; avoid customer names, addresses, number plates and saved map locations in public posts.
Models & softwareWhy doesn’t the supplied frame or connector fit?
Contact support with photos of your original radio, dashboard, supplied frame and connectors, along with your vehicle details and TEYES model. The correct parts depend on the vehicle variant and factory equipment. Have support verify the kit before cutting the dashboard, modifying the head unit or forcing a connector.
Audio & microphonesAre all TEYES external microphones interchangeable?
No. The CC4 Pro uses a digital external microphone. The CC4 and CC4L use an analogue mono external microphone. Use the correct microphone for your model.
Cameras & accessoriesWhat size memory card does my TEYES DVR support?
The TEYES DVR used with CC3, CC3 2K, CC2 Plus, CC3L and LUX One supports a maximum microSD card capacity of 32 GB. This limit applies to the DVR, not to separate 360 recording storage. For other models or recorders, confirm the applicable limit with support.
Models & softwareWill my original vehicle functions be retained?
Ask support to assess each function you need for the exact vehicle, factory system and installation kit. Separate parking sensor sound from its graphics, camera video from automatic reverse activation, and ordinary steering keys from call or voice keys. Working functions in a different trim are not a guarantee for yours.
CarPlay & connectivityDoes working Bluetooth mean every Bluetooth accessory is supported?
No. Successful phone pairing does not guarantee compatibility with other Bluetooth accessories. There are many Bluetooth devices available, and we have not tested them all to confirm compatibility.
Cameras & accessoriesIs the CC4 PRO compatible with a 360 camera system?
All CC4 PRO are 360 ready. In order to activate this feature you must purchase the CC4 PRO 360 system. This comes with an activation card to enable 360.
CarPlay & connectivityI connect the unit to the internet via WIFI but there is no data.
Make sure the Date and Time is set correctly on the unit. The same issue can happen on regular tablets and computers.

CarPlay & connectivityDoes my TEYES support wired or wireless CarPlay and Android Auto?
CC4 supports both wired and wireless CarPlay and Android Auto. LUX One, CC3, CC3 2K, CC3L and CC3LW support wireless CarPlay and wired Android Auto. For units running Android 10, wireless Android Auto is not officially supported. Some customers using phones running Android 12 or later report that it works after initial setup through Carlink using USB, but compatibility is not guaranteed. For guaranteed wireless Android Auto, use the linked adapter.
Audio & microphonesCan you map Siri or Google Assistant to a steering wheel button instead of TEYES Voice?
No currently it is not possible. But others have installed google voice from the play store and uninstalled teyes voice to get it to work.
CarPlay & connectivityCan I hotspot internet using my phone or do I need to use a dedicated SIM card?
You can hotspot internet from your phone to the head unit. Alternatively you can use the internal or external SIM card slot for the unit.
Audio & microphonesIs DAB+ inbuilt?
No you must purchase a seperate DAB+ module (here)
Audio & microphonesDoes my OEM DAB+ work with this?
Original DAB reception, the original aerial and a TEYES USB DAB receiver are separate components. Do not assume the original DAB system carries over when replacing the head unit. Check the receiver and aerial connection requirements for the exact vehicle and unit before buying an adapter.

Settings & passwordsHow do I do a factory reset?
Use the reset instructions for your exact model. A factory reset clears stored data and settings, so save what you need first and record the current configuration. A normal reboot is a different operation and should not be described as a factory reset. If you are unsure which operation is needed, contact support.
Settings & passwordsMy themes recently starting defaulting, how can I resolve it?
Go to Settings --> Device --> APPs --> Disable Digital Well-being app
Audio & microphonesWhat is the output power of the CC3?
The CC3 is rated at 4 x 45RMS @ 2Ω
Audio & microphonesWhat are Pre-Out RCA Voltage?
The CC3 has been tested between 2.68VAC - 2.28VAC
Cameras & accessoriesCan I retain my original reverse camera?
Not all harnesses retain factory reverse cameras. Compatibility is assessed individually because there are thousands of harness packages for different vehicles. Many customers choose to upgrade their original camera because its lower-resolution image can look washed out and pixelated on a larger, higher-definition screen. For this reason, we recommend upgrading the camera.
Audio & microphonesDo I need the external microphone?
An external microphone can give better placement near the driver, but the result depends on the correct microphone, installation and settings. Confirm the microphone type for your exact model. If calls sound poor, compare a direct Bluetooth call with a CarPlay or Android Auto call and tell support which connection has the problem.
Audio & microphonesCan I use my vehicle’s original microphone?
For CC3, CC3 2K, CC3L and LUX One, see our factory-microphone connection guide. Check that the instructions match your exact model. The CC4 Pro uses a digital external microphone; the CC4 and CC4L use an analogue mono external microphone.
Audio & microphonesHow do I improve external microphone quality?
First identify the exact unit, microphone type and motherboard revision. The internal/external microphone-switch guide applies to supported newer CC3 and CC3 2K boards; use the separate digital microphone instructions for CC4 Pro. Do not remove the internal microphone as a general troubleshooting step. If the microphone works in Bluetooth calls but fails in projection, use the CarPlay and Android Auto fault-finding guide.
Microphone switch guide · CarPlay and Android Auto fault finding
Cameras & accessoriesWhich USB connection should I use for a DVR or TPMS accessory?
Use the port specified for the exact head unit and accessory. A factory USB-retention lead or hub adds another part to the connection and may need its own compatibility check. Tell support whether the accessory works directly on the supplied lead and whether other data devices are detected. Do not apply an older model’s port restrictions to every unit.
Models & softwareDoes the T'Eyes custom frames match my dash?
The images may not look identical in real life as its impossible for photos to look the same. There may be slight variances in texture and colour to what you see as different batches of frames are manufactured.
Models & softwareWhere can I compare the CC3 and CC2 Plus?
Compare the models in the specification comparison. Check current product listings for available models.

Support & warrantyWhy is there no user manual in my package?
Due to the immense amount of functions and features, the information on T'EYES systems is too large. Updates occur quite often to improve user experience, so we use an User Manual in how to videos. We have moved to this guide form for over 3 years now with no problem. You can find it here.
Models & softwareCan the CC2 Plus and CC2L Plus software be upgraded to CC3?
The CC3 technology is very different from the CC2 editions, therefore they cannot be upgraded to CC3 software.
Even if you try to force an update, it will not work due to various system constraints.
Support & warrantyCan I root the T'Eyes system?
Rooting the device will void warranty.
Models & softwareWhat is TEYES Online?

Support & warrantyIf I have to return an item, how do I do it?
In case of any problematic or incomprehensible question regarding T'EYES products, first of all you need to contact our customer support service.
Models & softwareWhy has the CC3 been added with a cooling fan located outside the device case?
Firstly, the fan isn't required due to the CPU chipset which runs more efficiently, faster and cooler than its predecessors. However, T'EYES aim to go above and beyond our reliability, quality and longevity, we decided to include one anyway.
If the fan is installed inside the case, it would lead to a significant thickening of the back cover of the device. Due to the limited internal space of the center panel, it will become impossible to install the head unit in a range of cars. In addition, if the cooling fan is outside, it is easier to replace in the unlikelihood it needs to as fan failure has proven to be extremely rare.
Models & softwareWill T'EYES add new styling to the main interface of the CC3 in the future?
Yes, we are actively working to improve all our products.
Cameras & accessoriesCan the CC3 record the rear camera?
Since the June 2021 firmware this now enables recording of the reverse camera to a USB drive!
Models & softwareWill there be more new 3D images for CC3 T'EYES Vision in the future?
The CC3 firmware will no longer have new features added after its production has been discontinued in early 2026. Bug fixes in future firmware updates will still be ongoing however.
