Then you should be careful with your statements.
Recordings, logs, logos, backups, etc. are stored in /Documents/DAB/... and are not deleted when App is uninstalled.
Stationlist, favorite list and related settings, RadioDNS downloaded logos and all settings done in the Settings of DAB-Z are deleted at uninstall time.

I can confirm this statement.All downloads, logos and stuff keeps in there when uninstalling the app.
Only Android firmware updates mostly delete all these files too, because this will also format the user data partition.

First question, what kind of antenna do you have, one that sticks on the windshield or an antenna on the roof?
Second question is, where is the DAB+ receiver placed, in the glove compartment or near a fusebox?
An external antenna is the best and place the DAB+ receiver far away from the radio and fuse boxes.
I had the same problem like you now experiences.
I placed the DAB+ receiver in the trunk and use a external antenna and have now stable reception, even from stations who were hard to receive, with the lights on or off.
My antenna is embedded on the roof.
The receiver is behind the radio.
what is the fuse box you mean?

Dobrý den, myslel jsem, že aplikace je pouze v angličtině, ale viděl jsem na Youtube, že je také v italštině. Je tedy možné nastavit jiný jazyk? V nastavení jsem nic nenašel.

Sorry, I entered a different text by mistake.
Once again: Hello, I thought the application was only in English, but I saw on Youtube that it is also in Italian. So is it possible to set another language? I couldn't find anything in the settings.

Try it for sure, it's maybe annoying to reroute the antenna wire and to install a long shielded usb cable between the radio and the DAB+ receiver, but your reception will far more better then before.
cannot confirm. Made may experiments before installing it in my car - with short and long antennas, with DAB adapter placed near to antenna (in roof), in A-pillar, behind HU, near glove compartment - no difference for my combination of hardware. Now my DAB adapter is located 40 cm from radio, because it is connected via USB hub, and in my car there is a compartment with easy access to it, aimed to put GPS antenna, but there is enough space to put there also hub with several devices.
Also tried to wrap adapter in tin foil, connect it to ground, etc - no difference.
The only big (really big) difference for me was switching from window-glued antenna (that came with adapter) to active FM/DAB antenna on the roof.
So - it could be, that your experience is different, but it can be just combination of your DAB adapter+HU+some other electronic under your dash, emitting RF, but not the common case for all.

|fyi| I've installed DAB-Z on my android PX5 car unit , using AGAMA as home car launcher. The problem at start was however that agama is displaying air music notifications (see picture) Agama Airmusic setting had to be turned off. DAB-Z is now working perfect!!

Then you're lucky. My experience is similar with that of Alexander. I have a BMW E46, and installed a Xtrons px5 with 9 inch radio, the screen can affect the dab+ signal, when i turn off the lights i got bad reception with a brighter screen, if i turn the lights on much better reception with low screen brightness but still not good. I have an external sharkfin antenna on my roof and i also wrap the adapter in tin foil, connect it to ground but it din't work. When i instalded a new CC3 radio, i moved the adapter from the glove box in to my trunk whitch its connected to an powered industrial Tripp Lite 7 ports usb hub. The reception tremendously improved, even so good that i now can receive Dutch radio channels, that's 10 to 15 km from the Dutch border from were i live.

Hi. I have a Teyes cc3 with a no kill script so apps aren’t terminated when the headunit sleeps. When my headunit sleeps if dabz was the active app it will be running when my headunit wakes but if dabz is running in the background playing and the unit sleeps dabz gets closed. Any ideas?

Had the same problem so I removed DAB-Z from the list of apps which shouldn't be killed before sleep mode.
I think it has to do something with initialization. USB may not be ready immediately after sleep mode. I have similar problems if I start DAB-Z to fast after booting the system. DAB-Z stucks on splash screen and I have to switch temporarily to another app which may re-execute the "onResume" activity of DAB-Z. Would be great if it would be possible to handle the adapter init more aggressively.

Hi all,
this question might have been asked already but it is almost impossible to find anything by searching the thread so here we go.

Is it possible to have an FM-station backup in the app if the DAB+ reception drops?
I had this on my last Pioneer headunit and it synced the FM-radio with the DAB aswell.

If this is not an option, could it be in the future?

Thanks!

If you have a Teyes CC3 then why don't use the builtin settings to restart DAB-Z on boot/coming from deep sleep. It is standard functionality on the FYT usi7862/uis8514a units. In Settings -> User - > Application Setting.
No fidling with nokill scripts and the like.

    where are you located? Are you sure that there is some DAB+ broadcasting in your area? check here pls https://www.worlddab.org/countries/italy#coverage
    Moreover, your DAB antenna has been installed wrongly (as I see from your picture) - the last part (farmost from antenna housing) should be connected to unpainted metal part of your car - read/watch installation manuals for that type of antenna.

    Hi, I've just tested my Avin 4 BMW system again this morning. Neither of my 2 phones were connected to the system. WiFi is turned off on the head unit too. But I still get the annoying ducking on LBC London.... I dont think it's the station as we have DAB in the house and the signal and audio are perfect. The Avin 4 has been factory reset also and that has made no difference. I am now wondering if it's the latest DAB-Z causing this issue as I dont recall earlier versions of DAB-Z having this problem. Do you think that's possible at all? Many thanks, David
    If you think a former version did not show this issue, you can try to sideload an older version. Just have a look at https://apkfab.com/de/dab-z-player-for-dab-dab-usb-adapters/com.zoulou.dab, there you can find older versions for testing.
    As already been mentioned by realzoulou: If your unit is rooted, please provide a logcat DAB-z --> Settings -->Info

    Frequently asked questions FAQ:

    DAB-Z's expected behavior regarding Play/Pause, Mute/Unmute, Navi App announcements

    Q: Does DAB-Z support fallback to FM Radio?
    A: No and it is not planned due to technical reasons.

    Q: Why do some stations appear several times in the list but have all the same content?
    A: This is an annoying behavior of the broadcasting stations. DAB-Z does not lump them together to give the user the choice to pick one into the favorites list that has the best signal strength.

    For testers ...​

    ... that want to actively support me and help everyone to have a better DAB-Z app:

    If you encounter an issue with DAB-Z, I will maybe ask you to provide a) logcat logs or b) raw recordings.

    a) logcat logs are created by pressing the logcat button in DAB-Z Settings -> Info (at the very bottom)
    A zip file is created and you will be able to choose what to do (send via Email, add to Google Drive, etc...). Get this zip file to me somehow.
    If I additionally ask you to enable "OMRI verbose logging", then follow these steps before creating the logcat as above:

    1. Enable Developer Menu: tap 7x on DAB-Z Settings->Info->Version , then go back, a new menu item appeared "Developer options" at the very bottom
    2. Enable OMRI verbose logging
    3. Close DAB-Z
    4. Reopen DAB-Z
    ... reproduce the issue ...
    5. Create the logcat DAB-Z Settings -> Info (at the very bottom)

    b) raw recording are created by this procedure:

    raw recordings are done using this procedure:
    1. Enable Developer Menu: tap 7x on Settings->Info->Version , then go back, a new menu item appeared "Developer options" at the very bottom
    2. Enable OMRI raw recording (you don't need to activate verbose logging)
    3. Close DAB-Z (raw recording enable/disable requires a restart of DAB-Z)
    4. Reopen DAB-Z
    ... reproduce the issue ...
    6. Go to DAB-Z Settings and disable OMRI raw recording. Restart DAB-Z again.

    Afterwards, files with ending .raw exist in:
    <internal memory>/Documents/DAB/rec/
    Download them all from the head unit, zip them and send to me.

    Release ZOU-DAB+171119 "Master Piece"

    Release of the "Master Piece" version of the DAB+ App mod.
    ZOU-DAB+171119

    Changes (see also Changes.txt from the download):

    New:
    - Station logos
    Station logos can be downloaded from Volkswagen for >20 countries across Europe and automatically installed to a User accessible location. More than one country can be installed. User can add own station logos in subfolder "<extStorageDir>/DAB/logos/user" in JPG or PNG format. No width/height restrictions for the logo. The app will automatically scale to fit.
    Settings allow to enable/disable showing station logos in station list and in Slide Show area. Scaling can be limited to 1x,2x,3x if needed.
    Settings list any issues in finding a matching logo for a certain station. The search is based on the station name. If no exact (substring) match can be found in the list of logo files, then a default logo is presented. The User has to fix this by renaming logo files or adding additional logo files outside(!) of the DAB app using a File Manager.
    - Layout:
    * new button icons
    * button bar moved from left to right side to gain more space for the slide show area
    * Changed the "logic" of the favorites button: Shows what will happen when pressing it, not what the current status is.
    * new "radio.png" logo. Using now a new DAB logo used in Germany (www.digitalradio.de)
    * the background boxes are not disabled by default. Can be reactivated in Settings.
    * General layout optimization for
    - 800x480 @ 320 dpi
    - 800x480 @ 240 dpi
    - 1024x600 @ 320 dpi
    - 1024x600 @ 240 dpi
    - Removed the previously added "Large SLS" activity. Replaced with an animated fade out of the station list.
    - Added an option to automatically hide the stationlist after a selectable timeout.
    - Added Audio format (MP2 or AAC) and Sample rate (44,1 or 48 kHz) to Station details. As before in the Large SLS, still accessible via "flipping" the slide show picture.
    - Added an option in Settings to move the App to background when the DAB App was started by the "USB device attached" event. Useful eg. when using certain launchers.
    - New logo in the notification bar.
    - Settings->Info shows the reason why the DAB App is running: Either started by "LAUNCHER" or "USB DEVICE ATTACHED"
    - Settings->Info shows the screen resolution and density (e.g. 1024x600 @ 160 dpi)
    - When scanning with type "update", old stations no longer received are now deleted. The favorite setting will be kept.
    - Added Italian translation. Thanks to John Dai @ china-rns.com

    Changes:
    - Replaced old "Connecting..." behaviour with a completely new implementation
    - Audio recording now stored in <extStorageDir>/DAB/rec/ (instead of <extStorageDir>/dab_rec/)
    - Fixed: Channels "10N, 11N and 12N" not shown in station details
    - for developers: BroadcastIntent generation is now disabled by default. Can be reactivated in Settings.
    BroadcastIntent definition has changed w.r.t. "artist", "track" and "playing". See change documentation in BroadcastIntent-definition.txt

    Note that the high pitch sound issue is not fixed in the 171119 release.

    Release ZOU-DAB+180804 "Master Piece Maintenance Release 5"

    Release of the "Master Piece Maintenance Release 5" version of the DAB+ App mod.

    ZOU-DAB+180804

    Download: http://bit.ly/2Kqp7HB
    (Please only share the bitly link with others)

    Changes (see also Changes.txt from the download)

    - BroadcastIntent: added slsBitmap which contains currently displayed logo or DAB slideshow picture
    Goal: Allow launchers (e.g. FCC Car launcher) to display album art
    INFO: DAB App now also has a fairly complete implementation of Android's android.media.browse.MediaBrowserService interface
    This allows for using pure Android APIs to view metadata instead of using the proprietary BroadcastIntent
    - Add buttons for PREV and NEXT to Notification and use Media style notification
    - PREV/NEXT steering wheel behavior can be swapped in Settings->General
    - Fixed: Volume adjustment in Settings->Audio is lost after station change
    - Fixed: After several station scans, App completely fails to work until re-install.
    - Fixed: Duplicate entries in station list
    - Removed feature to delay the USB connection on automatic start, which was introduced with ZOU-DAB+180210
    - Removed option to avoid that DAB App is started twice from Settings->General. This is now avoided by using Android manifest launchMode=singleTask
    - Removed feature to download a country-specific station logo zip file and automatically extract it.
    Note: You can still copy an extracted folder of such station logos to /DAB/logos/ folder and after pressing "Sync" button in Settings->Station Logo the logo files will be scanned for a match between filename of a png/jpg file and the name of a station.

    Release ZOU-DAB+180618 "Master Piece Maintenance Release 4"

    Release of the "Master Piece Maintenance Release 4" version of the DAB+ App mod.

    ZOU-DAB+180618

    Changes (see also Changes.txt from the download)

    - Fixed: Adopt Station Logo download to new VW website
    - Add a button to Settings->Info to show hints picture about how to use the UI

    Release ZOU-DAB+170909

    Release of my next major version of the DAB+ App mod.
    ZOU-DAB+170909
    This is not the "master piece" release yet.

    Download: REMOVED

    There are (again) two versions of the App:
    a) the "normal" one
    b) one with no usb_device_filter.xml included, which makes Android remember already granted access of DAB+ App to the USB DAB device.
    However, Android then also starts the DAB+ App whenever it finds the USB DAB device as newly connected, which is the case when you power on the
    head unit.
    Some people don't want that the DAB+ app starts automatically when the DAB USB device is detected at startup. This is the reason why this version exists.
    Note: When running on Android >= 6, this version will most likely ask for permission to access the USB device at *every* start of the app.

    Changes (see also the Changes.txt from the download):

    New:
    - Most (not all) of the texts are now available in: English, Deutsch and Norsk bokmål
    Credits for translation to Norwegian goes to XDA member [B @[email protected][/B]
    - Swipe to right in station list shows a delete button. On swipe left again, delete button disappears. On click on delete button an alert dialog appears to allow the user to confirm. Deletion of stations cannot be un-done. A new scan is needed to get the station back.
    - Additional info (channel and ensemble name) in station list can be deactivated via Settings->Layout
    - "Service Following" feature can be activated in Settings->General. NOTE: This is treated as "Experimental". This activates the original app functionality, which was always in the app, but was not connected to the UI. Do not blame me if you find it not working.
    - Audio recording button can be activated via Settings->General
    - The borders around the slide show picture and around the station list can be deactivated via Settings->Layout
    - A click on the slide show picture creates a large version of the picture. I call this "Large SLS".
    - Swipe left or right on "Large SLS" switches between the picture and some detailled info about the current station.
    - When starting a re-scan one can choose now between "Replace all stations" and "Add new stations"
    - The app sends out broadcast intents containing all information that you can also find on the screen.
    The definition of the intent is in file "BroadcastIntent-definition.txt"

    Changes:
    - Fixed: no audio after standby when using NoKill mods.
    - Fixed: when USB connection suddenly drops, the App remains active but with no audio. My fix is to close the app.
    - Settings layout improved
    - Notification now contains station name instead of "Make DAB+ great again ..."
    - A second way to enter the settings screen is via the "Large SLS" screen
    - Optimization of memory allocations. Results in less Garbage Collector runs, which is good for overall performance.
