I can't comment about the other guy

But for me
Adapter harness is pluged in
and have the prober connection

And it communicating with head unit

Also i have used an older unit and it works fine there

My only problem with this unit
Is after programming the key for the steering wheel
They work fine
until reboot or restart or deep sleep
They stop working

For now i have installed a Bluetooth remote control on the steering wheel that i got from dudu

I hope they can fix the issue

    Abogrhen well some hyundai ix35 got canbus depending what originaly came headunit...some units come with biger screens, navigation, revrsecameras etc...my were simple fm radio, cd unit and bluetooth conection for phone...so you think it cant show without canbus decoder

      this is cable foe my car

          I do understand now. Your cable only contains the radio conection. It is not a complete ISO harness for all the other functionality.

          Could this work for your ix35?

                  Did you ask your Hyundai dealer if there is a complete ISO harness available?
                  There are also many hyundai forums and clubs on the internet. Maybe in your own language/country. Did you ask there if users know about a more complete ISO harness?

                    If I turn off the device completely (turn off the ignition and remove the battery), will the device forget these settings?

                      Kriss Not necessarily. Depends on your vehicle, canbus/no canbus. These are some exceptional cases. If your car/head unit uses a can us decoder this sould not be the case. I don't know what to say about disconnecting the battery.

                        Abogrhen
                        It would be worth checking to see if the ignition and battery wires are not interchanged at the ISO connector (yellow and red).

                        No CanBus. One Sony wired remote connects to Key1.
                        For me, it differs in that it only forgets the long button function. The short key function remains.

                        Kriss
                        No. The settings are stored in the app database on internal memory (on "disk"). That is how it works on Android.
                        If you do a firmware flash with complete wipe (twipe_all, twipe_data or format_data), you will lose your settings.

                            According to them, only the functions of the secondary button (long press) are not loaded from the flash.

                              Car: Kia Ceed 2013 JD (Non Canbus).

                              Problem: Long press volume + or - to change several clicks stop working after restart.
                              Steering wheel Volume+ and Volume- always work for a single click volume change.

                              If I learn and set it to:
                              Speaker+ 69, Speaker- 63
                              All ok.

                              Next time, single step work, but not long press. So I set:
                              Speaker+ 63, Speaker- 67

                              Next time, single step work, but not long press. So I set:
                              Speaker+ 69, Speaker- 63

                              Next time, single step work, but not long press. So I set:
                              Speaker+ 70, Speaker- 69

                              So almost always every time I have to re-learn the keys.
                              Steering wheel control working ok with the the original radio.

                              Should I make a thread under BUG REPORT instead of here?
                              I also have problem that the radio not stay in sleep. After say 8 hours or a day, it always start by booting (Should I make another thread about that)? How long is it set to stay in sleep?
                              I don't know if it can have effect on the steering wheel control.

                              Yesterday when I came to car.

                              It booted up from start. Long press worked. - All ok for that day

                              I can confirm that if the DUDU7 device is disconnected from the power supply (yellow cable), the long button presses no longer work.
                              They are still there in the settings. If you re-learn the long button press, it works again. But I think that you don't completely disconnect the HU from the battery in the car, so this is just a small error.

                              I'm also experiencing this issue with long-press volume keys on my Hyundai i30.

                              When I learn the Vol+ or Vol- keys, I can do single step volume or long-press the keys for multi-step volume control.
                              After a day or two I can only do single step volume, long-pressing for multi-step control stops working.

                              If I re-learn the SWC then it is working again until the next day or two, it stops again.

                                aKelso Try using a CANBUS bus box to see if that solves the problem.

                                    If the numbers change on your SWC buttons all the time, get your clock spring inspected at a shop. It will not keep its function when those numbers are not steady.

                                    I have noticed similar issues in my Pajero 2014 (non Rockford/CAN). It works sometimes and doesn't work other times. I had tested it by connecting back the original headunit and SWC works fine all the time.

                                    I had this problem with my Suzuki Swift Sport NZ ZC32S.
                                    I had to buy an extra steering wheel button canbus-box.
                                    The numbers always changed, but after i installed the box, everything was fine.
