I own a 2021 Toyota Corolla Hybrid Touring Sports and recently purchased the DUDU7. I’ve been experiencing problems mostly related to the CANBUS system.

Here’s a picture of the back of my original head unit:

Currently, I’m using the Raise CANBUS RZ-FT01. I’ve attached a screenshot for your reference:

When I bought the head unit from AliExpress, I encountered a payment issue. As a result, I had to purchase the head unit frame and wiring harness separately. I searched on Taobao and AliExpress, but I couldn’t find a wiring harness that could be plugged and played into my car system without any modifications.

After making the necessary modifications, the DUDU7 finally turned on. However, I’m still facing several issues related to the CANBUS system.

Only following is working normally:
The door information.
Sterling wheel button.

Everything else is either working partially or not at all.

Here are some of the issues I’ve encountered:

When I go to the “Vehicle information” section and select “Setup,” most of the items don’t respond.
The head unit doesn’t display radar information.
The air conditioning system cannot be controlled by the head unit (which is expected), but the screen can show some information (but not all) when I control it using the original car button.
When I use the Bluetooth phone, during a call, the car dashboard shows information about the call. However, after I hang up, the car dashboard still shows that I’m in a call, even after I quit the Bluetooth phone app. I have to reboot the head unit for the display in the car dashboard to become normal again.
An extra option called “Set the minute to 00” starts appearing on the car dashboard.

I also own a RZ-FT02, RZ-FT52, and I’ve tried plugging them in, but I’ve had the same issues as the RZ-FT01.

I also own SimpleSoft and Hiworld CANBUS boxes, but it seems there’s no corresponding car model in the CANBUS menu.

I’ve attached the CANBUS log when I tried to press some of the options on the “Setup” section of the “Vehicle information” for your reference.
