Review on 🚗 ZHNN Android 9.1 Car Stereo: 9-inch Double Din Touchscreen Player with GPS Navigation, Bluetooth, Mirror Link & Backup Camera Input by Marvin Breezy

For the price you really can't complain. Two annoying things that bother me a bit. First, you cannot change the home screen. That being said, you're stuck with the soundscape they put in there. He looks like Jack from Titanic. The home screen also shows your live speed with GPS. The only problem is that it turns on and off, meaning the speed changes from zero to any GPS speed every few seconds. I bought a separate GPS sensor thinking it might be the cause. nope I think it's a software problem. Either activate Google Maps or like me download a speedometer app. Second, it doesn't save any sound equalizer settings. It is reset when the stereo is turned off and on again.
