ATOTO S8 Ultra 2DIN Audio Android Car Navigation S8G2099UN This is the ATOTO 2DIN audio "S8 Ultra" Android car navigation system, model S8G2099UN. I've been using it for a few months, but it was installed in a third car, so it hasn't been driven 1000km. It works without any problems. It can also use a SIM card and can be used like a tablet. It has been reset to factory settings, but I connected CarPlay once for testing, so if you are concerned, please reset it to factory settings before use. Everything in the pictures is included.
