I honestly have no idea about the quality. If you're talking about audio quality etc, I'm no audio purist so anything works for me. I have the stock speaker setup and just installed this screen because the JVC panel was almost dead, also I needed a screen for the back camera. The panel looks just fine, It's not very bright but gets the job done. Bluetooth works just fine, if I have my phone's Bluetooth on it instantly connects which is also very good. I just went to Tariq Road with a friend whose driver knows a man there so I wouldn't be ripped off.
