Just thought I’d share this as I know quite a few people now have the Xtrons stereo units.
On the XDA Developers forum someone has released a free update that dramatically improves the sound output from these headunits as some people don’t think the sound quality from these units is very good especially with Audis with Bose.
I and another member on here have both got Bose and have both done this update and agree that it’s definately an improvement over how it comes out of the box.
To do this update go on the android auto section of the XDA Developers website and look for a thread titled (mod)(mcu)BD375xx sound processor.
It involves no hardware modifications, it is simply an MCU update and installing a new amplifier app.
The instructions are on the thread but you basically unzip the files on a computer/laptop and put the mcu update and new amplifier app onto an sd card and then place into the gps/map slot on the unit and install the update and app and that is it.
If you have a unit bought from Xtrons then you would do the GS mcu update, if you have a unit from someone else like erisin or whatever then it’s upto you to find out which mcu update you need to do.
The update is for android 6 and android 8 devices but if you have a different android version I’m sure there is a similar thread about the update for those devices.
After doing this update your sound quality and especially the bass will definitely be improved and if you use the new amplifier app you will have more control over the sound settings.
