New radio installation polo 2015 (mib1)

[monk2000]

Hi guys, maybe you can help me out.

I have an polo 2015/2016 with the mib1.
I bought an android stereo but when I connect the quadlock, it doesn't even power up.

Does anyone have the diagram for the quadlock so that I could compare the wiring?

Or does anyone else have an idea why it won't turn on?

(I tried the radio in my mates Passat and it worked)

Thanks
