Reply With QuoteHello everyone,
I am looking for a stable iGO NextGen / iGO World APK that works correctly on a modern Android 14 head unit.
Current setup:
Head unit: ZQC50
Android: 14
CPU: 6x Cortex-A55 + 2x Cortex-A75
RAM: 4 GB
Storage: 64 GB
Current iGO version:
9.18.27.687519
Build date: January 26, 2017
The navigation works fine, but I have one strange issue.
The navigation voice volume continuously resets itself. After every reboot it returns to about 10–30%, and the volume slider in iGO even moves by itself. Radio, Bluetooth and Android media volume all work normally. The problem only occurs inside iGO.
This exact APK worked perfectly on Android 11, so I suspect it is an Android 14 compatibility issue.
Things I already tried:
Different navigation_audio_stream values (3, 4 and 5)
Modified sys.txt
Deleted the save folder
Reinstalled the APK
Tested different voices
None of these solved the problem.
I would like to keep using my current content, maps, licenses, POIs, speedcams and voices, so I am looking for an APK that is fully compatible with the existing iGO_World folder structure, without having to replace or convert my current data.
Can anyone recommend a stable Android 14 compatible iGO NextGen/iGO World APK, preferably one that works well on ZQC50 / UIS7862-like head units and is compatible with the existing iGO_World content?
I found several posts mentioning 9.35.2.252374 working on Android 14, but before changing everything I would like to know which version people actually recommend for this hardware.
If anyone is already using iGO on a ZQC50 Android 14 unit without the navigation volume issue, I would really appreciate it if you could share the APK version and your experience.
Thanks in advance!

What should change in the language/voice with the same iGO APK version (9.35.xxx), unless there are different settings/variables/values in the SYS.txt file 🙄🤔
The TTS engine is always the same, since it's system-dependent.
For example, I have the same skin from the same skinner on all 64-bit versions, so the conditions are the same.
In my opinion, the error isn't with iGO, but rather with your system environment 🤔🤔

You chose a pretentious nickname.

You have a problem with the device, not the software. Browse through the topics about car devices and audio problems and the like, there are plenty of them.
And when you want to keep your old content, know that it can cause more problems than good.

Thank you for your response.
We know how to install an iGO application on an Android device. The question is mainly what you would advise in this specific situation, because the navigation audio volume keeps returning too low while the general system volume is already set to 100%.
Do you think this should be tested with:
a completely clean basic configuration;
without restoring old content or old settings;
a different or newer APK version of iGO NextGen;
or first through the audio settings of the device itself?
We would appreciate your advice on the best next step to test this properly.Last edited by Boki; Yesterday at 07:45 AM. Reason: approved

"We"?
First of all, you are in the wrong topic. I.e. in the wrong section
There are threads for installation problems, there is a section dedicated to voices

Everyone knows how to install iGO. Most of them do not know how to properly fit its content and components, and even less how to adjust it
It's always best to use a clean base pack. You can always try with another package, of course. Avic for example
However, I repeat, you have a problem with the device system. You should carefully go through its settings. Since it's an Android device, just like with mobile phones, permissions, drivers... all that affects. TTS has to be adjusted independently and it has almost nothing to do with iGO
It is possible that the device's launcher is causing the problem, whether it's his factory or a third party. You can always try some else
Also, it often happens that the system in such devices is crippled - that it lacks some components. Very difficult to solve
You wrote that that version of igo works great on Android 11. But more importantly - on another device. You can't compare
