    Three things are not working

    1. Reverse camera. When I put the car in reverse, the screen goes black for about a second, then returns to the dudu operation screen. I can't access the settings, the setting page loads but disappears.

    2. I am not able to skip songs with the steering wheel control buttons. The volume works fine, so there must be configuration issue. I've remapped the buttons, but the mapping isn't working.

    3. I'm not able to see vehicle data, such as open doors etc.

    Can you please advise? The other Android unit was working fine. I just switched the connectors on the back.

      Frodo changed the title to Prius Gen 4 (XW50) - faults with dudu 7 after replacing old android head unit .

      I also have a Gen 4 Prius, everything works fine. What canbus are you using? I tried Raise and Hiworld and both of those work.

        Frodo stupid question, I guess, but what's a canbus?

          VishBK stupid question, I guess, but what's a canbus?

            Nevermind the question, I see that it's some kind of adapter.

            When I google it I find several on AliExpress for around $5.

            Is there a particular one for Toyota, or will a generic do (assuming there is such a thing)?

            Did yours come with the head unit, or did you have to buy it separately?

              Frodo I had to buy it separately. Any Raise Toyota Prius one from AliExpress should do.

                  VishBK thanks, will do

                    For posterity, this issue is partially resolved when the AMP C cable from the harness is connected to the AMP CONT cable coming from the speaker output and SIM card connector cable. If you don't have an AMP C cable exposed, connecting the AMP CONT cable to the CANbus's ACC pin will work (in my case it was Pin 9)
                    After that, update the MCU by extracting the files from here into the root directory of a USB drive and restart the head unit. More information can be found in this post. The speakers should no longer pop when starting the car from a shutdown but will if manually rebooting (will be fixed in a future update).

                    Thanks, I don't have a popping sound. I think you might be replying to the wrong thread.
