Fake Android 10 version, real version is 8.1. Locked settings password (3368) Antenna off by default in settings. turning it on gives good FM reception but blocks Wifi signal. Shady tactics by seller to give only 3 year warranty if 5 star review given = Dishonest to other sellers. Unit does not turn off when ACC off, only when drivers door opens. Limited settings and badly written OEM apps. Unclear badly translated car settings menu. Seller stops communicating when confronted with fake android version number. The unit itself is good once rooted and own software on it. Avoid unless you write your own OS for it.
Good product - worth the money. Would trust the seller for more purchases!
