Just for sharing here.
Recently I bought a headunit, face plate and harness from Taobao, costing less than $150.
Touchscreen quality is as good as other branded head units, sound quality I have no comments.
Bascially it comes with a harness that fits to your vehicle without any cable cutting or whatsoever. Plug and Play.
Best it comes with andrioid auto and Apple Carplay.
I saw other basic headunit that cost than $100 with all in accessories.
My unit was a stock HU that was removed from a Nissan Vehicle.
They managed to do modification to the stock head unit to make it usable on any other Japanese/korean cars.
Just doing a sharing here. No sale or advertisement.
