I would like to greet the community of Dudu audio!
how is everyone's day?

First of all! specs.

Dudu 7 8gb 128gb storage
No 360 chip
Hyundai i20 2016
The car came with Navi and already had an after market tablet
Ainavi P48E DSP AMP

today we have in our hands the dudu 7 8gb 128gb for my car.
The car had already a multimedia screen installed. And since i have the car over a year now i went to upgrade my Multimedia experience.

And as soon started my installation everything went from good to worse...

the first problem was the screen although the 2K resolution is awesome for some reason it had those weird yellow spots keep in mind everything has been purchased through AliExpress but it was packaged well I don't see why the screen has to be damaged but we don't mind that.
although the multimedia screen doesn't have my specific car model I chose a different car and the controls worked correctly for a while but after working with the screen for about 1 day the controls started acting weird for example I pressed the volume button once and the volume May increase 5 to 10 levels and as of today the controls don't work at all ( Still waiting from Aliexpress shop to tell me what is going on)
things are getting better and better because yesterday for some reason when I turned on the lights I started hearing ground look noise on my speakers this was not present at all with my old multimedia screen and I don't think the car just randomly started breaking down because I have neither gone out to do any kind of service Beyond changing the multimedia screen everything started after that..

right now I have changed the multimedia screen for my old one of course. as it seems the canbus system is fried the controls don't work and the ground Loop noise didn't stop after the installation of my old multimedia...

so in summary everything is fine (No its not...)
