  • SWC button no response after sleep

Yah
on thing i can think of
Is that some services that handled this goes to sleep and don't work again

But on "canbus" cars the canbus wake the service up so that doesn't happen to them

      Abogrhen Settings - Automotive - Startup Settings - Set to off when engine is off, is this ok?

          dudu-lai
          This is the current setup
          Should i try to set it as shutdown ?

            I tried the shutdown setting
            But no difference

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

              Thanks for the suggestion
              But as far as I know
              There is no canbus available for my car
              (Hyundai elantra 2010 )

              As it older model with standard ISO connection as the car came with JVC unit from factory and later on upgrade it to Kenwood unit
              Before moving to android head unit
              And all of them worked with SWC button

              And as the buttons work fine when programmed it's clearly a software bug

              Any way i have ordered my self the dudu Bluetooth remote to solve the problem for now

              But i hope that you can flag this problem and try to get into it later on

                11 days later

                hy, im driving also hyundai ix35, 2012 (year of production - car model without CANBUS), only cable, i have question regarding head lights ON/OFF, doors ON/OFF (it shows on car command displey/desktop)...does lights on/off, door on/off only works with CNBUS, or it support some car models without CANBUS?? my swc works solid, only sometimes it dont show volume up/down graphic on screen, and and some buttons are slow to response but i think it is related to usage during years

                  It is not possible that your car doesn' t have CANbus.
                  CANbus is one of five protocols in OBD-II
                  2001: The European Union makes EOBD mandatory for all gasoline (petrol) vehicles sold in the European Union, starting in MY2001 (see European emission standards Directive 98/69/EC).
                  2003: The European Union makes EOBD mandatory for all diesel vehicles sold in the European Union
                  2008: All cars sold in the United States are required to use the ISO 15765-4 signaling standard (a variant of the Controller Area Network (CAN) bus).

                  See also ISO 15765-4.3:2001 “Road Vehicles-Diagnostics on Controller Area Network (CAN)—Part 4: Requirements for emission-related systems”, (December 14, 2001)

                  So, by law, worldwide, every car has to have CANbus for control of emissions.
                  Actually your car does not have "a" canbus, Most cars have 5-9 CANbuses connected to the several systems in the car.

                  What you proablably mean is that you ordered a unit without CANbus decoder.

                      Hi although you're replying to @obelix80
                      Your are correct that all cars have obd2 protocol connection nowadays

                      What we mean here is newer cars have a connection to the car radio that make it (smart) by getting some information from other systems

                      Like if the door is open or if the head light is turned on and many more
                      So need to decode the signal
                      So you use a canbus decoder

                      Unfortunately some economy older
                      Japanese - Korean cars think 2015 and older do not have that

                      And use simple ISO radio connections that not communicating with car at this level

                      My car came originally with an aftermarket style one din stereo

                          OK. I understand.
                          Your car simply does not have the CANbus Hi Lo wires (and some more) connected into the ISO plug, or si it seems.

                          Is it not possible via Hyundai or some other source to get an extended ISO plug?

                            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

                                    obelix80
                                    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.
