PROS: The product is ok - work fast and properly. No delays when starting or changing applications. Sound better than original, sceen and video quality from youtube - perfect. CONS: rear and front partronics are not showen on the screen, so you can hear only sound with no visual. Heating control - everything work except temperature regulation and there are no webasto regulation at all. LTE - radio offenly loose the connection if you are switching between different applications - data connection on/off helps. Wase application - doesnt work, it crashes and stops wprking all the time. SELLER - is not communicative! a lot of my messages are still unread or unanswered more than a week.
