About this deal
The USB wire attached cannot be removed from the head unit. This will make the installation quite a pain in some cases. In my car I needed to take the whole front plate off and push the wires out. The head unit has a lot of different customization options. For example, you can change the wallpaper and startup logo of the head unit.

The price! The head unit was about 225€ compared to 350€+ for premium brands. This was the biggest reason for me to try a Chinese head unit in the first place. Firmware update just involved unzIpping the file to the root of a USB drive and plugging it into the USB port on my A6 PF. The stereo updated itself from there. Its features are good. It has ability to be hooked up to a rear camera and a subwoofer, which were the requirements for me.
It has fast charging while using Android Auto. My phone has a very old battery which means I can finally keep it alive during long drives. With my old head unit, I always lost battery while driving. Currently I'm gaining about 1% every few minutes. The bass does not have its own slider. It needs to be changed directly from the EQ which makes it difficult for "normal" people. Startup time is okay. The startup time is lower than in my old head unit, ~10 seconds to boot + ~10 seconds for Android Auto to be fully initialized.
