    surfer63 I run much time Dab-Z ,therefore for me are extremely rare the situations outside the major cities, when opening NavRadio+ works very fine and RDS works. Some users when upgrade stock car head units doesn't know the specs of proper aerial. There are passive and active aerial system, the active ones need to be powered under 12v from car wiring or via Dudu head unit. If no power comes to antenna a poor signal is normal. Some Toyota, Subarus, Renault and BMW, VW need 12v+ power (blue wire). This option in included in Dudu wiring specs. I get DuduAuto 7870 -7, all works fine.

        trap63 The power supply of the antenna amplifier is not taken into account, when it comes to the antenna installation, I am sure that everything is connected correctly.

          surfer63 Navradio is cool but I like the dudu FM radio app more, it works day and night when you turn on the lights. It displays the station name on the bottom bar, FM station logos also work. The only problem is AF. The dudu FM radio app was created from scratch, it is developing well.

              trap63 Scusami, ma RDS funziona perché da il nome? ok lo fa anche a me, però se si viaggia il cambio di frequenza quando serve non avviene, rimane sulla stessa frequenza nonostante il segnale sia molto disturbato. Come fai a dire che RDS funziona bene ! non funziona affatto per niente, e poi l'antenna non centra nulla perché con l'autoradio originale va benissimo ( oltretutto ho l'antenna amplificata di serie) e cambia benissimo la frequenza migliore quando serve. Quindi ribadisco che AF è nullo. Forse se vogliamo AF ma in maniera minima funziona sul TS10 topway. Penso che AF non potrà funzionare mai perché il problema resta nella scheda madre, dove non è stato considerato bene il progetto AF, mi potrei sbagliare spero !!!

                    Well, speaking for myself, I'm using NavRadio for nearly five years now with several headunits, and with Dudu 7 it would be around 10 months. So I've tested it well enough, I guess. And as I said, NavRadio simply cannot handle RDS functions any better, because it doesn't have access to all the necessary data (ideally full RDS stream, or at least full RDS AF table, RDS error rate, radio signal etc.) and it depends on the RDS and radio functions available from firmware. So it shares the same radio base functions like stock radio app, therefore it will work the same way. With the only slight exception of FYT 7862 units, where Kotix managed to somewhat reimplement the AF function with RadioProxy companion app...
                    That said, AF and other RDS functions (namely TP/TA which on Dudu7 doesn't work at all) depends on firmware and needs to be addressed by Dudu developers.

                      Pietro I don't know if you're right, AF worked better in the previous radio app, the steering wheel buttons didn't work and that was a minus.

                          But to be honest, fot me the AF on Dudu 7 works on probably the same level as on Topway TS10. On my trips, I'm driving regulary, it sometimes works as it should, correctly jumps to right strong frequency when signal drops. Sometimes it takes a few minutes of false tries, when it finally manages to jump to correct one. And sometimes it doesn't work at all, constantly trying some wrong noisy frequency or jums to a freqency of completely different station.
                          So, to sum it all up, we can all agree that the RDS AF is definitely partially broken and this needs to be addressed by Dudu devs. As a few users here already pointed out, they hopefully know about this and will try to improve it, so let's give them time to work ;-)
                          If needed, I can help with testing, make for example videos of the good or bad behaviour, send RDS data (PI code, AF lists,... ) of affected stations and so on.

                                jamar mi piace la tua disamina! In poche parole hai evidenziato il problema AF. Si speriamo che ci sia impegno da parte degli sviluppatori 😅

                                  In China, FM radio is a thing of the past. If more people write about the AF problem, there is a chance that developers will do something about it.

                                      wybitny2 Si esatto, dobbiamo cercare di evidenziare in maniera costante il problema frequenza AF. E chi vuole condividere con noi lo stesso problema è ben accetto.

                                        i recantly install the 3.5 software and i get activation warning massege , what should i do??!

                                          You have the telegram them to request into beta or buy a headunit.

                                          What happens though if you got registered after installing any way to make the warning go away?

                                            Hi guys,

                                            Anyone having trouble in dudu 3.6 with contacts sync? Cannot get to the bottom of this.
                                            Dudu5 7862, iphone 13 & Huawei gt runner setup..
                                            Thank you!

                                              @YAOXILONG @caolz Even if I have nothing connected to the phone (headphones, watch) but only the DUDU 7 is connected on Bluetooth devices of the iPhone, there are times when I access the phone app and it says contacts not synced.
                                              The annoying thing is that sometimes the contacts get synced, but sometimes like one in 5-6 cases they just don't want to sync.

                                              I want to calm everyone down, developers are working on improving AF in dudu radios. They realize that the topic needs to be improved.

                                                Tell us, does dudu7 13inc support audio output to USB audio? We plan to use it with Helix DSP 2 via USB. Thank you.
