To prevent upgrade errors, we have removed the public download links for MCU firmware. This is because required versions differ across models (e.g., G13, Vivid11) and even production batches.
If you are experiencing CAN Bus issues, steering wheel control problems, or other MCU-related malfunctions, please contact our support team directly. We will provide you with the correct firmware for your specific device.
Thank you for your understanding.
Hola. Tengo el G13 y necesito el MCU correcto para mi Toyota 4runner 2015 con llave Inteligente.
@Paulo Villalba Could you please let us know the issue so that we could check if MCU update is needed or not?
Salve mi potreste dire l'ultimo aggiornamento mcu per il px6 max10 ?grazie
@Vittorio Menconi Hi there, we do not suggest MCU update if the radio is working in good condition.
Hi, I have this model PX5: MTCE_HA_V3.40db_1.
The issue that I have is that the Radio stopped working. Everything is fine, but I cannot listen to the radio.
A new MCU could solve this? If yes, can you help me with this?
@Support Dasaita non mi va assolutamente la radio..
@Marcelo Eguino We are wondering if you have already proceed the factory reset or not, we don't have newer MCU for PX5 currently.
If stil no luck after the factory reset, it may be hardware issue.

Hello，
Thank you for your details.
After checking the ASIN :B0FWB291NX , the parcel doesn't include a plug and play cable. It is universal unit.
If you bought the Canbus from Oudi,please go Settings>Car>Factory Settings:126 >Canbus>To Select the related choice.
Thank you for your time.
