Just installed the 3.8 version on my Dudu7 with Dualsystem support on my Honda Civic FK8 Type R, model year 2020.
So far most stuff works, except the canbus has some problems:
-Climate Control window does not pop up when i turn on the climate. Even with the beta canbus and old climate control activated.
-Open doors are not shown.
-No climatic temperature output on the new navigation bar.
-SWC buttons, except voice which also not functions on 3.7 work. So i can switch titles and can raise lower volume without any problems. This means the canbox communicates seems to work.
I think it has something to do with the new deeply adapted canbus. My box is included in the compatible list:
6606-Honda-CRV-2017-2023.Keep original-(393664) (CRV has the same canbus as the civic).

On the CANBUS following text changed:
3.7 - 6606-Honda-CRV-2017-2023.Keep original(393664)-CAN_BOX_HODA-26-0811-V045
3.8 - 6606-Honda-CRV( [393664] (6<<16) | 448)-CAN_BOX_HODA-26-0811-V045
