Thread: Tomtom_Go_Navigazione_e_Traffico_v1.17.5_Build_2128_Patched_By_DFoX

I have not run into any of these problems running Oreo on my Hauwei P20 lite.
TTS voices have worked.

As for the gap from 1.17.1 to 1.17.2 was that TomTom was waiting while testing Android Pie.

Yes a lot of user's were not happy with their smartphones after upgrading to Pie and TomTomGO then had menu problems.
But there were work rounds to get the menu fixed.
They found that there were some problems with 1.17.2 and came out with 1.17.3 then some small problems then showed up and the final fix was 1.17.5

All the TomtomGo versions have worked for me on all the versions of Android from 4.4 on up.

As for the new TomTom v 1.0.5 app it works with no problems also with TTS voices on Android 8 and on Android 6

I think you need to wipe both versions of TomTom from your smartphone and start over.

That means removing the both folders on both versions of TomTom from the memory and the SD card.
Shut the phone down and restart and install clean.

No backup a clean install for both.

PS:
Only use DFoX version with his signing not any other signed version.

I would to play it safe go to his forum and download directly his patched version.
