last week I buy this stereo ( http://www.autopumpkin.com/car-dvd-play ... ntrol.html ), for my VW Golf 6.
Immediately, after the installation, I see that the steering wheel and the can-bus channel don't work..



Now, after 1 day, [when the car is stops, appears a Chinese written with logo with a blue background and does not allow me to use any command.
Do you have an idea what can i do to solve these problems ??
Thank you to all!!
