  • Add DAB+ chip to Dudu units

As far as I know it is a directive, not a law. Most say it is end of 2031, like in Schleswig-Holstein.
But it is also dependent on FM concessions in some countries that are given for 12 years. In Norway, where they wanted to stop earlier, they extended it also until end of 2031. Due to the 12 years concessions until 2035, court cases will start.
In the Netherlands, where I live, they also have the date till end of 2031. However also here in NL the FM concessions for the several public and commercial stations run until end of 2035 and in the Netherlands it has already been decided that FM will "stay on" till end of 2035.

And if you read all the info on the internet for the several countries worldwide, they think that FM will remain for decades, also in the EU.
We will see what happens. Ever so often "advanced insights" have changed decisions that were made years ago.
Next to that: Most technicians say that DAB+ should also be replaced by something better and more advanced.

      surfer63 In Italy all FM analogic concessions are expired on 12.2024. A recent law (2022) estimated and propose shut down by 2031. On the other side today more than 44% of broadcast are now on DAB and signal/MTU is fully covered all over the country with limitations due to specific areas (mountains, hills, little village) and not populated rural towns.

        Generally I like the idea and also proposed this to the developers.

        Well working FM/DAB radio is still important in Europe.

          That Italian law is not in the Netherlands.
          All country wide and regional stations in the Netherlands are currently both on DAB+ and on FM and can be received country wide (no mountains in the Netherlands 🙂).
          Only some smaller local (city wide) stations are only on FM.
          It is not on the stations side. It is on the receiver side.
          In NL only 30% of households and/or cars have DAB. I assume it is not different in other countries.
          That is the limiting factor.

          Edit: I don't drive much, about 10 hours per month. In about 50% of the cases, ~ 5 hours, I listen to the radio. I currently switched to only online radio at 128 or 192 kbps. That is 300-600MBs per month with always crystal clear "reception". Of course it helps that we also have data coverage everywhere in the Netherlands.

          ciubaka Since 2018 almost automotive producers introduced in EU car the DAB decoder onto head units (Stellantis, Renault, VAG Group, BMW, Benz and so on, Toyota EU too), therefore the big issue are now the domestic (house) devices and oldest head unit in car. SF works well in Italy and in Northern Italy signal is fully covered. A big help came from the approved in law of 5G rules for freeing frequencies (DVBT/DTT/DAB). A big help might come to adopt and include internal board decoder in head units. Mekede might think to EU sales. Maybe a plus.

            To add to @trap63 request.
            This should include 2 connections:

            • For cars with a simple FM/DAB+ radio (to be replaced) and already a roof DAB+ enabled antenna.
            • And for cars without DAB+ antenna which need a windshield or dashboard or other external antenna

            What kind of device/antenna can I use to get dab+ on a dudu7 radio?

              BasTijs DAB frequencies aerial enabled, windshield mount or roof mount and USB stick.

                  I totally support this.

                  Note that based on the metal coatings on your windscreens, your reception may be better or worse with a windshield antenna. In my previous Skoda octavia I had excellent reception. In my current Skoda Octavia, having darker windows, reception is horrible. I simply can' t use DAB anymore.

                  And I simply don' t want to go through the hassle of replacing my FM/GPS roof antenna for a FM/DAB/GPS antenna and completely remove and re-attach the inner roofing material to install the cables.

                      surfer63 Hello, do you have the part no. of the roof antenna?

                          trap63

                          No, I don't. Of course I searched for it on Amazon, AliExpress and on the briskoda forum, but as I did not want to go through with all the hassle of the inner roofing lining, and in the worst case with a leaking roof, I really can' t remember it.
                          There were multiple possibilities though and there are videos on YouTube describing how to do it.

                            surfer63 I use a splitter, it makes the FM antenna usable for the DAB receiver as well. Works well, just make sure to get one with phantom voltage supply if the antenna needs it.

                                🙂 I also tried that, with 2 separate splitters. First one one with phantom power supply. It didn' t work.
                                Then one without phantom power supply (although I knew it had to have phantom power), and that one didn't work either.

                                    surfer63 ahh, too bad

                                      @gismo
                                      Just to make sure.
                                      I have one of these "Universal DAB AM FM booster splitters".

                                      I assume that is what you mean?

                                      Note also that I have for my Skoda already a facra-2-fm adapter.

                                      That is why I tried both with a powered and unpowered splitter.
                                      (hardware is really my weak spot 🙂 )

                                      Edit: I assumed that the "Keep antenna always ON" setting will set tthe " phantom power" already on the signal, meaning that I could use the simple splitter.
                                      Or should I use the 12V power on the power cable of the splitter and disable "Keep antenna always ON"?
                                      The last time I tried this was early 2022 in my "new(er)" Skoda octavia. I simply can't remember.

                                      I now remember that I also consulted my garage in early 2022 about it.
                                      If the sharkfin antenna is an active antenna it will have a frequency band filter. Some of these filters do block the DAB frequency.
                                      So I asked whether that could be the case with my Skoda Ocatavia 2015, but nobody knew in that garage.
                                      That could be another reason why I could not get it to work.

                                        Like older antennas from Suzuki before DAB antennas.
                                        They are blocking DAB frequencys to, so no splitter is working.

                                          surfer63 ok all VW (etc) have active antennas though and I have a splitter branded RTA that works for mine. For an active antenna, there are many options, eg at https://www.rta-mobile.com/browse/#/category/528541-1/0/0/0/0/0/0
                                          If you are certain that your antenna amp blocks DAB frequencies then you'll have to swap the antenna or at least the antenna amplifier (have seen replacements somewhere at RTA also, scroll down for Skoda)
