Yuehoo android head unit stuck on sync screen

Bought an android radio unit called yuehoo for ford kuga 2015.

It's stuck on a SYNC screen. Every time I tap to go to home or settings etc it goes there for approximately 1 second and then goes back to the sync screen with Chinese writing.

Any advice greatly appreciated. Yes hard reset done many times already.

 

Image attached. Reverse camera works fine and stays on.

 

I've placed a video here also.

 

Here's the spec https://uk-m.banggood.com/YUEHOO-9-...60.html?cur_warehouse=CN&ID=6281274&rmmds=buy

Thanks,

This is the response from the seller. Are they correct?

hi friend for this problem, it is the canbus problem, replace new canbus is ok, would you like to replace new canbus ? if yes, please close the return case, we will send you new canbus from Germany warehouse

 

They have also said this:

I am sorry for the inconvenience caused.Please don't worry, we will try our best to help you.
could you please remove this cable,check the radio can be turn on or not, and please send me the canbus photo , may be it's the canbus problem.
Thank you so much for your time.

 

I don't have any way of testing the radio. I'd have to take it to a garage and they will charge.

Is there a psu i could get that would let me power up the unit without me having to install it in the car?

 

Attached are images of the canbas they requested

 

And the canbus they are referring to

 

Yeah, think you're right. Just sending it all back is the best option.
