Review on 🚗 10" Android 11 Head Unit Car Stereo: Apple Carplay & Android Auto, 4G SIM Card Slot, WiFi, GPS, BT, Double Din Car Radio - Mirror Link (Android/iOS), Backup Camera, 3 USB by Brian Malith

1/4 page "manual" for the rear camera on paper only with the device. There is no manufacturer's name on the packaging other than "Made in China". Amazon's online store Fellowstar sells generic Chinese toys, cosmetics, clothing, over-the-counter medicines and items sold in dollar stores. Fellowstar.com is blocked by my browser even though it exists. While it's a great device, it seems to lack any manufacturer support, documentation, or maintenance option. The metal case has a very small volume, maybe the heat conduction to the metal case provides good cooling? If a fan is required, what happens when dust clogs internal parts? What do the 2 cut off coaxial cables on the camera connector mean? According to the letters molded into the metal case, the Wi-Fi and "5G" antenna is a 2cm diameter plastic connector that partially protrudes from the metal case. The electricity is not connected due to the lack of information on how to connect to the brake, reversing lights, etc. If Fellowstar does not provide further information, it will be returned.
