if you plan on branded, pioneer etc. a good system might cost you slightly over a lack for a 9 inch one
next good option could be a used/second hand pioneer or kenwood 7 inch japense screen with english interface. it may cost around 25k and its worth evey penny
the most common thing these days is android 10 inch wala, its sound is ok, like a tv but screen is exceptional, dont expect much from it, its just a good video player with a laggy navigation. if you could get a good system with actual 2gb ot 1 gb ram, it may cost around 20 to 25k
the screen by tracking world in aspire is awesome, i am using it with MX player, its equilizer settings produce awesome sound, i am also running ptcl smart tv on it, it has a sim slot (but you need to pull out the system to insert sim), works very well, i would say its one of the best androids i came across, aftermarket it will cost you something like 60K but its worth it
