For sale: Carlinkit Android unit, version 13, with root access. Root features include original YouTube without ads or lag because it's from the Google Play Store with its original servers, along with Xposed features. Most importantly, Viper4Android, which completely modifies the system's sound, including surround sound, bass, treble, and more, making your speakers sound like Mark Levinson. It also includes overclocking the unit via Lspeed through root. Whoever buys it will thank me. The unit is well-maintained, new, and faster than others in navigation.
