    Merci, bonne et heureuse année!

    Hi,
    I am currently using Dudu 3.5 (V241222), can I install Dudu 3.6?

      Dudu OS has become more responsive, it keeps applications in RAM better. Or maybe I'm making it up, but that's how I feel. Of course, I always restore factory settings.

        lockc No, it is not necessary. As long as you don't move the files from Factory Reset folder tot the root of USB (leave the file structure untouched) your settings will be preserved.

          Since day one i didn't do a factory reset with an update. Working nicely until now.
          Bought it in March 2024

          Is there any way to update to this beta release WITHOUT using USB? I have tried the on device (downloaded the .7z directly from Chrome to downloads directory) but I believe for Beta updates, this does not work. Reason being....the Dudu is in my kids car and it seems the USB (both the external cord and the OEM connection) has stopped working. Maybe a short? Dirt might have got into the USB extension. ugh.

              Спасибо за обновление. Скачал на флешку. Поставлю отпишусь. Приятного отдыха.

              Tswire I think I've heard that it is possible from the root dir of the head unit. I think you have to extract the .7z

                  lockc I think it's worth doing this because sometimes minor bugs happen and something might not work as it should. Unless you notice minor errors, you do not need to perform a factory reset.

                    thanks, will give it a try today. I have it extracted but in the downloads. Need to fix the USB port anyway but eager to try 3.6

                      Tried that and didn’t work. Copied both the 7z and the extracted files to highest directory I could (Local) and then tried a local Update pointing to each. Neither worked. Hmm

                      Edit. Rebooting head unit seemed to work. Found the update file and doing it now. Probably have to delete those files after

                        Not sure what items 6 and 10 with respect to added car integration and more advanced integration entails? Like more brands of cars? If so Nissan is left i the dust again.

                        Tswire i upload it to the screen with the share app. My usb do not work as well..

                            Weird. I did just check the USB and it charges and works for other things. Hmmm. Ya as long as you extract the 7z and place all the files into Local (root) and reboot your unit it works. It also deletes the zip and other things after installing

                              FM radio alternative frequencies work in one direction, it searches for an alternative stops and does not return to the previous one.In my opinion it does not work properly, alternative stations should not be saved as an additional FM station in memory.FM radio and alternative radio stations work on the principle that the radio virtually remembers an alternative FM station and switches automatically.That's why it doesn't go back to the previous radio station because it doesn't remember the FM stations virtually. Previously, radio stations received better reception, now they fade out more often and do not receive signal.

                                Well, I don't understand what do you mean that it woks only in one direction, I haven't experienced anything like that in this version. Actually, there is no need to store the alternative frequencies anyhow, because AF list of the surrounding transmitters should be transmitted in RDS on each of the station's frequecny, so after switching to new frequency, it shoul load AF list from that transmitter.
                                Anyway, so far I didn't find any noticeable difference in AF behaviour between previous version 3.5 an now the 3.6 on my main unit installed in my car. I'm testing it also on my secondary test unit I have now on my desk in the office, I'll try to sum up my findings with the AF when I find some time to play with it....

                                    RDS alternate frequencies (up to 25 according the standard) should be sent in the RDS metadata in the RDS stream transmitted by the station. The tuner doesn't need to "search". The tuner needs to check the alternate frequencies in the RDS metadata stream, while comparing it with the pi-code of that radio station. It can simply "jump" from one frequency to the next. So if it simply checks and encounters a stronger frequency, but having a different pi-code, it should not switch.

                                    RDS doesn' t work correctly at the moment. It is a hit and miss.
                                    Sometimes it works correct.
                                    But sometimes you have a perfectly strong signal and suddenly it switches to a completely different station on a completely different frequency with a completely different pi-code.
