Bro I got the Chinese player installed in my ride last week, I compared many brands and spent almost 2 hours running from shop to shop taking demo of different brands. Here's what I concluded:
1. 8" one is better than 9" in terms of display as the 9" one is kinda dim. Though the 8" display is also not as good as my previous unit (pioneer)
2 I took demos of Avt, dellson, clarion (fake), Caliber and Premier. Talking about the display resolution and touch, Caliber was No.1 and at no.2 was Premier, the rest had touch issues.
Rest everything including user interface and sound quality was same.
I opted for Premier 8" although Caliber had slightly better touch but the shopkeeper who had Caliber was offering very less for my previous head unit.
The problem I noticed is that the software is not very user friendly and during day time on a sunny day you can hardly see anything on the screen.
This unit costed me 13,500(only unit)
I'll get the back cam installed after 2-3 months when I've checked my car thoroughly as installing back cam voids the car's warranty
