Hello everyone, i have bought chinese RNABAU Android (multimedia) and i have error when turn of car Faulty Starter RELAY, VISIT WORKSHOP. I have unpluged Hiworld canbus from multimedia and i dont have anymore that error on dashboard. Is it problem with canbus or is it problem with wiring. 

Please don't use unknown chinese parts.  There is no information on what this device might actually be or what the electronics actually are inside (any person can put a label on the front of a plastic box).  Remember the first rule of buying cheap products: buy cheap, buy twice.

I guess a faulty canbus box.

I tried several Chinese units and never had this issue.

As @varaderoguy said, you buy cheap you get cheap.
