CarPlay CarPlay adapter to convert to wireless CarPlay?

Works great on my 10.25 in 2021 Sonata. Running the March build. Only wish the audio delay was a bit lower (can be annoying on phone calls) and that the start up time was faster. Neither of these will probably change with updates so I probably won't bother updating the unit anymore.
 
Agree the delay particularly with phone calls can be annoying - I saw someone mention it maybe possible to lower the latency with this with a custom build would definitely be happy to test that out!

Is it possible to downgrade from 2021-04-26 to 2020-12-10 ( this is the only one working properrly for me)
I tried to install the march 2021 version but I am not able to install it. There is also no option to rollback

The latest 2021-04-26 gives me black screens and no sound with Spotify. Also not able to downgrade to the march version. Using the CarPlay2Air dongle (no custom FW).

Anybody with a solution? The march version worked for me without any problems.

Update: found the solution here in this topic:
"To update directly you just have to put the U2W.sh and ARMimg_maker (old decryption method) as well as the image because I kept the new decryption binary inside the CFW hoping I can break it some day to encrypt new CFW using the new encryption method ( and avoiding this extra step )

People with official firmware (>= 2021.03.06) have to downgrade using "U2W_Update_2020.11.10.2138_ROLLBACK.img" because it is the only image encrypted with the new method but restoring the old binary."

Worked like a charme. Thanks!

Will this fix a dongle that was working fine for me, then 1 say just got solid red light. Nothing works, tried a USB flash with what’s on 21-03-06, tried a newer FW but wouldn’t even start the flashing procedure. Won’t see it via the WiFi on iPhone for setting page either.

Is a cheapo USB-C one from Amazon. If so could you please reply and do a step by step for me on what to do and I’ll try this. It’s just if I can’t fix, Amazon will just refund me I expect as none of the cheapo ones are on Amazon now

Thanks

Try to rename the file U2W_Update_2020.11.10.2138_ROLLBACK.img to U2W_AUTOKIT_Update.img. Even though this is not an AUTOKIT device doing this I was able to update and perform downgrades.
 
Guys, I need help. My car is a Chevrolet equipped with the latest generation of Mylink (called Mylink3). I bought the Carlikit CPC200-U2W Plus, but it only connected once. Soon after, when I get in the car it tries to start every approx. 30 seconds, but reboots and gets stuck in that cycle.
The device has the latest firmware available.
Thanks in advance!

Sorry I can’t help you there. My issue lied within Mazda’s firmware update. It caused the car to not recognize the adapter as a CarPlay device. It still had WiFi. I’ve always had my adapter on the March update. Rolling back the car firmware to the previous one fixed my issue.

Is that My Link 3? I'm still got no luck on that in my 2021 Chevy Tracker, it works for around 15 seconds and then suddenly stops working.

Do you have any updates? I have 2020 chevrolet Onix with Mylink 3 and I was able to use the Carlinkit runing the .sh file that Renato made, but it is still inconvenient, since you have to do all the process every time. Thanks!

I belive the Brazil MyLink 3 is not the same the another country. It can be different in every country. But I followed these steps to get it work.

1) I Update my cplay2air to ludwig 2021.01.28 firmware.

2) It works good at first connect, but it does not reconnect. You have to reset the cplay2air from the webinterface (192.168.50.2) and reconnect every time.

3) I created one script that resets cplay2air every starting. You have to put that script in a pendrive and keep it pluged in cplay2air. The script name need to be U2W.sh.

4) Every start you have to configure the cplay2air again.

5) It is not perfect, but still it is one way that I can use the cplay2air on my MyLink 3.

Bash: 
#!/bin/sh

# ver se o arquivo existe em etc/bluetooth/
if [ -f /etc/bluetooth/mybluetooth.tar.gz ]; then
    # remover as configuracoes
    rm -f /etc/bluetooth/mybluetooth.tar.gz
    rm -f /etc/hichain/*
  
    # criar um novo serial
    echo `head /dev/urandom  |md5sum |awk '{print $1}'` > /etc/device_serial
  
    # sincronizar e reiniciar
    (sync;sleep 1;reboot)&
fi

Let me know if you had success.

Hello Renato! Do you have any updates? I also have an Onix with Mylink3. Thanks!

Hello joaoseh! Are you brazilian? I do not have good news. The last update does not solve this problem. I still need to use the script on pendrive.

Hey Renato! Yes, I'm Brazilian. Too bad we didn't get it :(
Do you know if we change our Mylink3 to 2021's model we'll be able to use the wireless car play?
