Humayun and Automakerz, Bhaiyo I bought this unit for 13000Rs. This one comes without DVD and its a 1GB Ram and 16GB Rom unit. Its a universal chinese unit.
Pros: Screen is HD and sound quality is pretty good, Comes with external GPS, 2 USB Slots
Cons: Low RAM causes bit of lag in launching apps and also closes apps in background but works fine in car.
Pure chinese thing its a Kitkat 4.4 based but they have some how change the about page and its written android 7.0 :p.
No SD Card slot.
I also saw another universal chinese unit with DVD option for 16500Rs that had a SD Card input as well. But you will be fine with USB Drive.
