The two big multiplexers I am talking about, 12C for public and 11C for commerical, ALL have full coverage in the Netherlands. I am not talking about local stations. See below the coverage for those big two multiplexers.

I do not know. How do I check that? I bought my module somewhere in 2018-2019 from Joying.

Let me rephrase my question from practical point of view:

I drive very regularly rental cars with a DAB+ unit in it. If I drive in the Netherlands from quite North to South, I pass quite some broadcast stations and I have DAB+ reception, without fall-back to FM, over more than 200 km for the stations in the two big multiplexers.

Yesterday I drove one of the routes with my own car. When in and leaving my home town (where there is a broadcasting station) I had reception. After about 20~30 kilometer I lost reception and could not receive any of those other stations either.

So either Service Follwing is available (the rental cars), or it is not necessary (the rental cars).

Then why can't the DAB module or DAB+ not do the same?
[Android Head-Units] NogenLunde:
I would guess that your car has a low quality antenna, not optimal placing, or bad connection to ground/chassis.

Try this: Do a manual scan when you reach an area where you lose reception. If the stations in question get reception now, there is a problem with SF. Else, your antenna is at fault (since we know there is good coverage there).

Can you find the specs somewhere?
[Android Head-Units] surfer63:
That was also my guess, but I tracked my entire route over the map for the stations I use, and when leaving my home town and "driving away", I am long in reach of the next station before losing my home-town station. And of course it can still be a bad antenna or bad grounding, but why still having reception from my home town station and not from the now nearer, stronger next station?

I did not do that yet. That might be a good idea, but that "destroys" the idea of not having to do this. And as it contains a number of actions I should actually stop the car.

After your previous reply Yesterday ("not all USB DAB ..") I started searching immediately :), but I can't find anything.

Still the antenna could be the cullpit. I have used the DAB+ module in my previous car where it did work (not with OMRI, but the previous library. Can´ t remember the name). For my new car I only purchased a new antenna.

And with regard to the Service followind as displayed/demo'ed under the spoiler in post #3290. I do not see that happening (not in the rental car either, but mayby these do that in the background). However, all Dutch stations (I listen to) stay in the same channel and are in the National Ensemble throughout the Netherlands (hence my other question: Is Service Following necessary in the Netherlands?)
[Android Head-Units] NogenLunde:
If I understand you correctly, you used the same DAB module in a previous car, with DAB-Z in none-OMRI mode (i.e. libdab mode), and had good reception on the same route you now lose signal?

You could always try an older version with libdab (1.7.x or 1.8.x), see link to older versions on the first page.

I would check the your antenna again. Remember ground is important.

hi, i sent a conversation but maybe this way works better! how do you get dab-z to work in france? I try scanning but get no stations? do i have to retune to different frequencies somehow? thanks in advance
[Android Head-Units] IG_Vasilich:
last time i visited France with my car (beginning of 2022, Paris) i had no problems to scan stations and got plenty of stations. So i assume you are doing smth wrong. Have you ever get DAB stations with your setup? What antenna do you use? Where n France do you live? have you checked DAB coverage for your area?
[Android Head-Units] surfer63:
I did check my antenna. Grounding might be a problem but I can't improve it right now as the airbag is in the way and I certainly don't want to fiddle with the airbag.

I will think about the options and alternatives I have. Hopefully I can report back in some time with a working solution.

Thank you for your suggestions.

On my Head unit I have seen the SF indication on the top in the middle.

I have only seen this on Radio Flevoland and Radio Noord-Holland.

This doesn't work on any other station I've seen.

I live in the province of North Holland in the Netherlands
[Android Head-Units] surfer63:
Yes, you are correct.

By now I found that as well.

For the Netherlands we have a "DAB spectrumlaag 1" for country wide coverage in one channel and ensemble for public radio in 12C. And exactly the same (DAB spectrumlaag 2) for commercial stations in 11C. These don't need SF as they are throughout the country exactly the same from every cell tower in the Netherlands.

And then we have country wide smaller "local" stations transmitting via several channels and ensembles. They have and need Service Following in channels 5A, 5B, 6A, 7C, 8B en 12B.

Loving the new interface, you are the patron saint of Android headunits.
[Android Head-Units] surfer63:
To give some final feedback on my issues I reported here, which was still for 1.9.127.

Grounding was indeed an issue. I now connected a very thin isolated (but with endings stripped) electrical wire to the "grounding strip" of the window antenna and aligned this via the A-beam to behind my dashboard to bare metal. Now the grounding is OK. I needed the wire as I could not "scratch" the A-beam without interfering with my airbag.

However, my reception is indeed bad. In my home town, which has a cell tower, reception is off course fine.

I have now a different car (previous one total loss) and I simply bought a new unit, used the same DAB dongle and also purchased a new window antenna. Probably this new combination is not working fine.

But also: This newer car is more luxurious than the previous one and has slightly tinted windows (not that maffia dark), which my previous car had not. Maybe (or probably) that window coating also hinders reception.

Thinking of other solutions right now, but that might be continued in the 2.0 thread.
[Android Head-Units] TorstenH:
Maybe you should think about replacing the roof antenna of the car.
[Android Head-Units] surfer63:
My car has a shark antenna on the roof.

When purchased new in 2015 (I bought it second hand Jan 2022) my car had 3 options for media unit: simple, middle and expensive (middle also being expensive by the way). The expensive unit had DAB. The other 2 not.

I simply can't believe they connect a different antenna and wiring on/under the roof, at the early stages of production with a bare metal car body, when in the end of the manufacturing process, as last steps, a customer can choose between having one of these units built in. So I called the garage (and another one) last Thursday and asked them about that: They had no idea.

So now I simply ordered a FM/DAB antenna splitter without amplifier and one with amplifier on AliExpress, and will try them out (25-30 days waiting though or pay 5x as much for the same brand splitter at Amazon or a carparts website, which is for me not a money question but a decision in principle. Making some money by importing and arranging is OK. 5x as expensive: no way)

If it works it has another benefit: I can simply remove the windscreen antenna and have everything "behind" the unit.
[Android Head-Units] TorstenH:
Due to the design, DAB reception on shark antennas is never as good as on conventional ones. Windshield antennas are even worse.

Nevertheless there are good DAB shark antennas on the market:

Hai Antenne aktiv - FM/DAB+ Set mit 5 m Kabelset

Shark Fin Dachantenne mit folgenden Funktionen und Eigenschaften: - DAB-Empfang, aktiv und rauscharm in dem Band III - Rundfunkempfang, aktiv und rauscharm für AM/FM - 12V-Stromversorgung wahlweise über Innenleiter der Kabelanschlüsse (...

www.dietzshop.de

Not the cheapest option but the cheapest option regarding nerves and time. And it gives the option to switch to a high end device as soon as the Android unit needs to be thrown out of the window.
[Android Head-Units] surfer63:
Thanks. But when the unit needs to be thrown out of the window, it is because I will have a car with a nice integrated unit ;)
[Android Head-Units] Tony2k:
Why when I turn on my headunit I need always to press play if I disabled start in paused mode function?
[Android Head-Units] realzoulou:
Must be some other app, e.g. your launcher, that plays some audio and causes therefore that DAB-Z looses the audio focus.

Or some other software sends a Pause command to DAB-Z.

Hi,

sorry in advance if the topic has already been discussed

I just upgraded my car radio from android 10 to android12 (MIC AV8V7). My son really likes to record songs with dab-z! :) But after upgrading to android 12, the mediaplayer (Music Folder Player) cannot find these recordings in internal storage /documents/dab/rec anymore. I think it´s because there is the hidden file .nomedia in it. Deleting it was not successfull, because after starting the radio again, this file exists again.

So my question is, is it possible to change the destination folder of the recordings to external storage or is there any other way to fix it?

Thank you!

There is an autoplay function in DAB-Z?
[Android Head-Units] Chard71:
Downloaded this today, and I absolutely love the new UI. Much better layout with the stations on the bottom, I think. It seems to be very stable so far. My only comments so far would be more theme colour choice, or even a slider to be able to choose a bespoke colour.

I am running this on an Xtrons Android 12 unit and can't seem to change the background image. It browses for an image, but "fails to select image"?

anyone have the same problem?

Expected behaviour
[Android Head-Units] Alexander_Kwame:
do you need to fix it?

the App didn't do that at first
[Android Head-Units] NogenLunde:
It doesn't do that on my radio. Have you tried to to a complete rescan, replacing the old list? If that doesn't work, you can always downgrade to a previous version (must uninstall first).

Or I might not have encountered this if service following has never been necessary on my trips?
[Android Head-Units] Alexander_Kwame:
I already done the rescan, doesn't change.

I try to reinstall...

it's possible that you didn't need the SF service
[Android Head-Units] realzoulou:
@Alexander_Kwame If during ServiceFollowing the app finds a new station, which it did not have in the complete station list yet, then it adds this to the station list.

If you want to control the station list, then I propose you create a favorites list. Favorite list is never touched by DAB-Z other than when changed via the UI.
[Android Head-Units] Alexander_Kwame:
For the new stations is correct but also saved the old station (the one that sounds) with a different frequency. like in my photo "DISCORADIO"

[Android Head-Units] pixel1:
Hello everyone! I like this app, only I would suggest to paint the UI a bit. Not only the header, but also the central panel or to allow us to choose our own wallpaper.

Before buying a USB DAB+ adapter, I would like to know if there are any interferences if I connect that USB DAB+ adapter and the car dash camera via a USB 2.0 Male to 2 Dual USB Female Jack Y Splitter cable?

Spoiler content hidden.

One USB port is occupied by a USB TPMS adapter, and the other is for music storage. So I only have one more USB port left. Will all these devices interfere with each other?
[Android Head-Units] IG_Vasilich:
@pixel1 forget about USB splitter cable - it can be used for power splitting, not for data. Take USB hub for it.

@modelman1968 ask in thread about your head unit - DAB-Z cannot remap buttons in any way.
[Android Head-Units] pixel1:
I'm OK with that, if that solves the problem and there's no interference between the USB TPMS, USB DAB+ and the Dash Cam that also connects to USB.

I would suggest to the developer a layout like this:

Spoiler content hidden.

I made this in a short amount of time and it's of poor quality, but it's just a suggestion and an idea anyway. For now, I'm only giving a suggestion as far as the appearance is concerned, because I haven't bought the dongle yet, so I can't say anything about the functionality. I hope realzoulou likes it.

EDIT: I should have made this post in the thread for version 2. This way the realzoulou won't see my suggestion.

Hello and good afternoon

I am thrilled with the app and would like to thank you very much for it! It is not self-evident that such a service is provided free of charge.

I have a very small problem (62 years old 😉):

When I turn on the car, Dab always starts with a message. I'll post a photo. Also, it is always in pause mode. How can I change this? I didn't find anything in the settings. There is no check mark at the start of the break.

Thanks for help!

Is possible to implement back key to return previous menu and home and long press back to close?
[Android Head-Units] realzoulou:
No, the root cause is that the 1.9.127 version has target API level 30 = Android 11

Because of Google decision here https://support.google.com/googleplay/android-developer/answer/11926878

I work as a car mechanic and have installed many dab radio for costumers.

Have also installed a few in my own cars without any issues.

However, i have two cars now, One 2009 Skoda Octavia MK2 and one 2012 Passat B7 using the DAB-Z program (which is awesome)

I have installed an Android Head unit in both cars, from same web sites but different units, but both have the same DAB+ antenna.

In the Skoda the DAB signal is perfect on all channels, strong and stable.

However, in the Passat its a mess.

When standing still at home, some channels can have full signal strength, others can have 2-3 bars and others no signal. Took the car out for a 45min drive today and the signal is absolute trash. It constantly goes from zero to 4-5 bars back and forth all the time, its not possible to listen to any channel.

Have anyone experienced this? I have tried to switch over the USB DAB unit from both cars, tried removing paint on the a-pillar to get better ground on the antenna but this did nothing.

I suspect either a bad antenna or something interfere with the DAB signal. I have tried disconnecting the GPS antenna and WiFi antenna from the head unit, The car also have a original installed GPS, could this interfere even if the antenna no longer connected?

Im a bif baffled by this.
[Android Head-Units] rigattoni:

station menu issue

well done, Realzoulou, but there is still an annoying issue, that should be fixed: if there are more stations scanned than can be listed on the menu's page #1, switching to page #2 fails. For example: if page #1 is showing stations #1 - #11 and you are switching from station #11 to #12 by pressing the screen's or steering wheel remote's "switch forward"-button, the menu should switch to page #2, showing stations #12 - #22. In fact, it does not. You are hearing station #12, but seeing menu's page #1 with stations #1 - #11. You can wipe with your finger to page #2, but as soon as you are pressing the "switch forward"-button to switch to next station #13, the menu will switch back to page #1. It would be great, really great, if you could fix that!
