Notice that there is also a CC2 plus and a Spro plus, that have more or less the same specifications.
The Teyes CC2 plus and Spro plus, does not have the extra ADAU1701 DSP and no gyroscope..

Well, really interesting.
Did you get any answers from vendor?
Their website is in russian language only and no translators can be used as all text is hard written into verifica l graphics.
Buy how to fit it in a standard 7" 2 DIN hole?

There is no difference between CC3 and CC2+/SPRO+ besides the board layout and the added ADI 1701 DSP in addition to the existing ROHM32107. Also has a proper control for controlling the fan. The others you had to enable the amplifier to power it on. All this information can be found on 4PDA.

no, but technically yes. Teyes has taken a new approach to DRM and have encrypted their app resources in .ogg containers. To decrypt them, it uses a key stored somewhere on the device, probably in a persistent partition, as a seed to generate the proper keys to unpack the .ogg. A member on 4PDA has already done this using partition dumps from another member's CC3 unit and has managed to decrypt all the apps. He has made a custom firmware with the apps already prepacked with decrypted resources and has some private testers. They all say it works for them minus some bugs which is also present in the original CC3 unit. It is claimed that the firmware was going to be released to the general public on 11/11/20 (today), but it's since been moved to "eventually". The only way to get the firmware now is by paying the guy. It's a shame that a community effort gets thrown behind a paywall.

Ok the difference in price between CC2+ and CC3 is 50 euro (buying the modified firmware will be even less), if i want to buy one or the other unit I'll definitively go straight for CC3.
Not cheap but it seem very attractive.

I know 4PDA, but as you know, its all in Russian, not a language that everybody speak.
Here on XDA its English which the whole world understand.

I thought that they said on 4PDA,that the CC3 also has a Gyroscope, can you confirm that?
Google translate translate Russian into Dutch, but sometimes translate the sentences or words on an odd way.

Ah yeah, forgot about the gyroscope, but its only purpose is for the TeyesVision app. Its what makes the car model shift to the left/right. It's just a gimmick.

It might also work with Maps when gps signal is absent.
Buy the way, does Maps run smoothly or is it crappy like on any other Chinese unit?

I don't own one of those devices so I cant comment regarding that. I would assume it does since the CPU is supposedly faster. I dont think the gyroscope would work anywhere else except TeyesVision since the gyroscope is accessed via an APK, so I'm assuming the gyroscope is not using native android libraries and its probably some closed source proprietary interface.

Should receive my unit by Dec. I will give my impression as soon as I install. Hopefully we can get someone who already received theirs to chime in.

    That solution is discussed on page 46 of this thread.

    I'm gonna have to try this too. I have also connected an external mic and it picks up no sounds at all. I do suspect that Teyes Voice is also interfering somehow. I can't use the external mic for phone calls, voice search or any recorder app, but it seems to work fine for Teyes Voice ...

    Just an update on this. I side-loaded a voice recorder app via apk file on to the teyes CC3 just to hear how my microphone quality is. I have an external mic plugged in and located in the roof dome light where there is a small blank vent. So the external mic is very close to me. Yet when i recorded a voice file with the car stationary, I struggled to get the voice level high. When i played back the recordings it souded like i was at the end of a room with the mic at the other end.

    I had this problem with 2 other brand head units that I installed for family members too. So it doesn't seem specific to Teyes. Afer reading the content on page 46 I decided to try removing the internal microphone completely. So I popped open the little access panel and disconnected the ribbon cable. This allowed me to remove the entire side bar PCB that contains the LED's for the soft buttons, the reset button and the microphone itself. I then de-soldered the internal mic completely and pictures are attached below.

    I can confirm at least for me this has made a huge difference. Recordings on the voice recorder app now are nice and loud (normal voice level) and most importantly, it doesn't sound like i'm at the end of the room speaking on loudspeaker.

    Ofcourse I cannot guarantee this is the actual cure but for me this has worked. Thanks everyone for advice and help.

    A humbling experience this is.. marchnz is going to enjoy it.

    I found the fault. A loose pin in the supplied kia connector.
    When I used my flash multimeter I must have been push enough to make contact with the steering wheel circuit resistance.
    Plug it into the AHU, and it would go open circuit.

    I only found it because I managed to loosen the single USB pins for the factory USB.

    This is a common problem in this type of pinout! Not exclusive to T'eyes

    Desoldering isn't necessary. There's instructions somewhere in this thread to tape the 2 mic pins on the ribbon cable. I just desoldered to be extra sure.

    I ended up finding how to access Engineer Mode via our Russian friends at 4pda.to. It involves opening the calculator app and entering a secret code (too afraid to link it since it's easy to permanently screw up you unit but if you search, you'll find it). Regardless, this was not helpful as there's no microphone level setting in there (also confirmed by people on 4pda.to). Maybe there's another secret settings menu I'm not aware of via Phone app?

    I just ordered a mic pre-amplifier https://www.amazon.com/gp/product/B08JHWSX2C/. It's cheaper on Aliexpress but didn't want to wait 2 weeks. It's not an ideal solution but I'm hoping it helps.


    Ooh, may try this. Any pointers for which files you changed and what settings you used?
    The information was in the main hardware post.

    persist.sys.zlink.mic.vol=9.9
    persist.audio.mic.senstivity=1
    persist.btmic.gain=10
    persist.btspk.gain=7

    Pop the above in a config file and reflash the firmware.

    This site seems to have much better guidelines on what will and what won't fit, compared to AliExpress.


    p.s. I saved a copy of that page into the Wayback Machine, in case it's of use to you in the near future. The page had not previously been copied. https://web.archive.org/web/2022092...ation-stereo-gps-android-10-no-2din-2-din-dvd
    The problem is that on all T'eyes sites, these two images contradict each other

    CC3 has the same connection. Do you believe i didn't asked them?
    Try asking on one of the many Astra forums. And show some respect to people trying to help. It usually goes better that way.

    Teyes announced another CC3 update for April 2021, here is the translated changelog.



    The following important updates are expected to be released for the CC3 software at the end of April.
    The new version will add the following features:

    1.Added Cam REC software. With this application, you can record from a rear view camera. The recording files are saved to a flash card.

    2.Added TEYES YAHU, the world's first 3D music player for the automotive industry (due to technical complexity, work may not be completed in April).

    3.In the device settings, a function has been added to change the screen brightness depending on the time of sunrise and sunset.

    4.The system version has been updated. Fixed the issue of crashing the Google Play app in some areas.

    5.Added setting for the sensitivity level of voice commands. If you feel that certain keywords easily trigger voice commands, you can lower the sensitivity level. In addition to Russian and English, a voice control function has been added for 7 countries.

    6.Added CAR LINK software which supports Android Auto via wired connection and Car Play via wired and wireless connection. Please note that CARPLAY only supports this feature on CC3 devices released in 2021. Android Auto has no limits. For CARPLAY wired connection, you must use the original iPhone USB cable. When using CARPLAY wirelessly, make sure the mobile phone is connected via Bluetooth.

    7.Updated EQ software and added a phase switch. The volume and sound effects of the subwoofer change according to the volume of the head unit.

    8.Added a new layout for the main screen, as well as automatic switching between day and night modes. From the home screen, you can directly speed dial, view driving data, compass and GPS information. The 4 main music players can be switched with one key. Redesigned and increased image size when viewed in picture-in-picture mode.

    9Optimized software for making Bluetooth phone calls. Added a choice of avatars in favorite contacts. Opened data synchronization with the main interface.

    10.Added TEYES RADIO and private internet station. Musical compositions can be downloaded and shared through the site mp3.teyes.ru

    11.Steering Wheel Key Customization Tutorial has been added for multiple languages.

    12.Added automatic OTA update function. In the future, we will provide 2 update methods: manual download update and automatic update.

    13.Added multi-finger touch control function. To find out how to use this feature, please see the personal settings section.

    14.Added the ability to slide the application menu to the right side of the screen. Swiping from below returns to the previous level. The function is supported no matter which interface you are in!

    Hi. earlier you said taht you dont't recommend buying Teyes for people outside Russia and now, that Teyes focuses on European region. What about other countries from Europe other than Russia? I'm from Poland and I own Ford Focus mk 3 (2011-1015)
    I am in France, and my CC3 gives me complete satisfaction on my Ford Focus 2. I do not see what the restrictions would be due to the development by the Russians

    Check if the OBD has good connection with the car socket. Pull it out and put it in again. Scan for Bluetooth devices and you must find it there. Also check the pins on the OBD adapter and the car socket, to see if there are any bent pins that don't connect properly. Also I think I heard somewhere that it's good to connect the OBD before you start the engine.
    Thank you for the advice. I did all of the above, but unfortunately with the same result as before.
    The CC3 sees the OBD2 adapter in the Bluetooth menu, but after some time attempting to connect I get a "Connected Unsuccessfully" message ( or at least that is what I believe it says, because the message is cut off )

    Also I would like to do a follow up regarding the new firmware. I can confirm that with it the device remains in sleep while the ignition of the car is off, even after 1h and 45min once the ignition was turned on the device woke up instantly. Where as before with the original firmware, after about 5min the device would do a clean / full boot.

    And for those looking to get Google assistant working a possible workaround would be to trigger the assistant via one of your steering wheel buttons.
    #1 go to Settings / General
    #2 Set the Google Assistant as the Navi App option
    #3 Go to Settings / Device / Steering Wheel Setting
    #4 Map one of your steering wheel buttons to launch the Navi app.

    Now just before anyone get way too excited, this is not a perfect solution.
    While I'm able to do things like opening apps ( YouTube, waze, 360 panorama app ) asking for direction via google maps, playing specific Playlist via Spotify. I discovered that it's not possible to make or receive phone calls via the assistant, and most likely there are other things that I did not test or discovered.
