I got today my wondefoo px6 which I ordered on aliexpress. The vendor asked me for multiple pictures of the cables in the car before he shipped the unit, so I'm quite sure that it should be fine. He also told me that the unit was tested before shipment.

Now I plugged the cable in the car but it won't boot. (I wasn't yet able to plug in the antenna as an adapter is still missing)
So the fan in the back doesn't run and there is no light or anything loading/blinking. Screen just remains black.

Anyone an idea why it won't boot? Or what else I could try?

Some pictures:

So I managed it to boot up. So if anyone has the same problem, I followed this steps (maybe do also first some research on can bus adapter/decoder):
  1. Check if you have 12v on the black/yellow wire on every single output until the end
  2. Now check if the black/red cable has 12v when the engine is powered on (the can bus adapter if you have one should handle this, in my case its the wrong decoder)
  3. If black/yellow and black/red have 12v then it might be the device which has a problem
In my case the can bus adapter (which handles the 12v on the red wire) did not send the ignition signal when the engine is powered on. So if thats your case you can try to bridge the yellow and red wire (this will send 12v to the red wire). After that my device powered on.

Here is a picture how I bridged the yellow and red cable (first I removed the can bus decoder)

I hope this will help anyone in the future. Good luck!

Sorry I thought the title is clear, it's a wondefoo px6 and I don't really have more information.

But anyways I fixed it. As I have a Mercedes A160 W168 I connected the Red wire to the A7 wire from the car and now it works perfectly. So there is no can bus adapter needed anymore.
