I tried this morning with the APK you posted but I could not get android auto to work, it would detect the phone, connect but then crash back to the home screen. The older version of the app is working well. Not sure if anyone else had this issue. When I installed this newer version I deleted the older version and cleared the cache before installing.

What would be the easiest way to root the CC3?

I think that I want root so that I can edit the config file to use my OBDLink MX1+ to use with the Tourque app.
Currently the CC3 only sees the teyes odbII adaptor that I also bought.
But the Teyes adaptor doesn't work with tourque, only the Teyes obd app.

There is a plethora of knowledge here: https://t.n3t.net/

I have a sub in my trunk and used the RCA sub out to drive it. I'm trying to configure the HP/LP filters for the sub along with the HP/LP filters for the front and rear channels. If I understand correctly the front, rear and sub should all work independent of each other but that hasn't been my experience. It seems like when I filter lows out of my front channel it's also filtering it out of the RCA sub out. This seems like a bug to me or maybe I just don't understand these settings correctly. Has anyone else had any luck with the filters?

Hello, I own a Toyota RAV 4 2017 and I have a problem connecting the steering wheel buttons to the CC3.
1. I successfully connected the volume up and down buttons, and when pressed, the volume slider appears, moves, but the volume itself does not change.
2. For the other buttons - receiving a call from a Bluetooth-connected phone and closing - nothing happens. Other buttons refuse to be mapped at all. Example: Changing radio stations and songs from the music player also does not work.


(I also have a problem connecting to the car's computer and displaying car information, changing settings, etc., but one at a time.)
I wont to continue the issue with Teyes cc3 and my Toyota RAV4 XA40 (model 2017). I've contacted the Teyes support thought WhatsApp and they'd wonted from me to make a video. Here is their respond:

"Your car does not need to set up a CANBUS model. After cancelling the CANBUS model, you can just hide and work."

So, my question is: Does anyone know how to cancel CANBUS model?

I did not set a CANBUS model at first!

Thank you in advance!

This is because of the flawed implementation in MCU code. It is what is is on these cheap units

1. Whait, so when buttons works in cc3 by default after connecting to canbus - they can't be remapped in simple way to individual settings?? Its huge limitation... i have 8 buttons and one knob by my steering wheel, by default 5 of them is usefull (vol+, vol-, mute, prev, next song [when using radio app that two not switching stations, but... switching frequency by Hz step :/ ]), others function is completly useless (one button switching in a circle by: nav, radio, video, something else that i dont remember now - i dont know who use this in real life :/ )... Maybe using Automate Llama app or similar i be able to remap this, I have to try, but this is insane that it must be done with custom app, not nativly :/...

2. Ok, but what about "Car information" app? Is it shoud works on every car when canbus works properly? And climate control widget should works on every "new" car?

Thx.

One day I will stop procrastinating, and reinstall my Wondefoo unit, and determine which canbus box it is using. I believe it is simply a matter of canbus model selection, that is keeping me from mapping the keys the way I want on the Teyes unit.

Yes, I noticed the same with the cc2+ unit. I suspect it's because the cc2+ uses a Canbus dongle rather than the key1/key2 wires for SWC.

My previous Wondefoo unit used a Canbus dongle also, but I was able to remap the steering wheel buttons.

Why would someone want to use Android Auto if they are already running Android on their head unit?

I'm asking as I have an Android head unit and am fairly satisfied without using Android Auto. Just want to understand better to see benefits of AA so I can decide whether or not to switch to it.

I am of the same thought as you. If you are going to use AA, then why buy a head unit that runs off of the Android OS? That's redundant. It would be like mirroring your phone to your television to watch Netflix, when your TV is a smart TV that already has Netflix available. If you are going to use AA, then might as well get a Pioneer, Kenwood, etc. Now, if your head unit has a weird shape, and it is hard to find a mounting kit to make the name brand aftermarket head units fit, then an Android car specific head unit(with the right shape, and pnp harness) is a good option.

My previous Wondefoo unit used a Canbus dongle also, but I was able to remap the steering wheel buttons.
We are talking about FYT units here which are all equal (that is T'eyes, Joying, NaviFly/Medeke, and a few other FYT based resellers).
FYT uses a "resistance" based approach on their motherboards upon assembling them.
In the corner of the motherboard (slightly different for a Sofia 3GR/PX5/sc9853i/uis7862) they have a double position for a mini resistor. (And this is valid for the FYT ones. I have no idea about the previous joying MTCx units)
If one has the resistor, the other should be "open". That means one has an infinite resistance (the open one) and the other a "slight" resistance (the one with the resistor).

One is connected to the key1/key2 wires. The other is connected to the CAN-bus.

The MCU bases it's SWC on the position that allows "current through-put".
If it is CAN-bus, there is nothing to configure. It is hard-coded in the CAN bus decoding code for that brand/model and simply starts the predefined apk or intent (BT).
If it is the key1/key2 side, you can completely configure buttons.

So in FYT models it is CAN OR key1/key2 based on the fact whether you have a CAN bus unit. I have a skoda with (previously) VW/Skoda/Seat/audi units which comes "soldered" as a CAN-bus model, but my Skoda has no steering wheel keys. It took quite some time to get that figured out with Joying. Now I have a universal model with a key1/key2 adapter on my steering wheel.

And for those who want to read on ;):
To overcome the CAN bus pre-defined commands, we started with mods of the main server apk on the Sofia 3GR. Then I wrote an Xposed module for the Sofia 3GR and PX5 that hooked on all key commands so that you could replace the commands with your own apk. Then I wrote the FytHWOneKey when on the sc9853i Xposed was no longer possible.
My FytHWOnekey is still a good solution for 90% of the cases, but only partially functional for the SRC/MOD button. Same for the very first main server mod.

Note that the SRC/MOD is a pain in the backside to remap.
First the MCU detects wiich hardware and software is available. You need both the radio chip and radio app for the radio option to be added to the SRC/MOD. Equally, you need both the DVD hardware and DVD app available to have it added to the SRC/MOD. Bluetooth options will also be added to SRC/MOD, but if you don't have a phone or 4G module connected, calling will not be one of the SRC/MOD options. Same for media play via BT if you don't have a phone connected.

    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

    So what apps do you primary use?

    Thanks

    Radio of course, Google Maps or sometimes Waze, and Spotify.

    Thanks surfer63! Now it starts making sense :)

    Just one last question (if you happen to know the answer :) ):
    I found this TEYES unit and another one - Dasaita. Is there big difference between these two? Or they are built on the same platform?

    Thanks!

    You asked two questions; Yes and no.

    Surfer63 is likely to give great advice. He might not suggest a "Teyes" which is actually a FYT unit and predominantly Russian market focused RESELLER / customized with software gimmicks.

    I'd suggest taking the time to read through the forums and know what it is you want to buy. If you take away anything from my post, it is to discard the concept of "brands" in the world of Chinese origin Android OS based head units.
    If you have any experience with Chinese origin Android "TV boxes" this might help you understand.

    My advice, forget the reseller "Teyes" and look to find a FYT based unit that meets your needs.

    Note that although I come from extensive MTCD/E/P experience, I have instead recently purchased two FYT units. I don't think I would buy another MTCx unit at this time.

    And one more question:

    what's the best source to read about different FYT-based units?

    Thanks!
    Here and 4pda.

    this is a glitch of new 2407 firmware. switch to new day_night theme and back and it will fix this sim icon
    Fixed.

    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.
