Pretty much all of our electronics are coming from China (iPhones, computers, etc.)... I don't think you can expect to pay $39 and expect a high end product, that's not realistic. Everything has a pricing tier and YGWYPF. When shopping for Android headunits, be sure to do your due diligence. If the vendor does not list specs or provide detail pics, it is a clear sign to avoid. While all 9" units 'look' alike, the specs are vastly different and I would not recommend anything sub ~200. I have a feeling the tablets you got does not have DSP or equipped with a very low output amp. Can you put a link to it?
The Boison is good b/c it has a DIN chassis (not flat like a tablet, which gets hot and heat is the ultimate killer. you cannot physically cram large capacitors), and has the latest PX6 CPU (as of 2-3 years ago).

I would not be surprise if there's a newer/faster processor on the market today since high end models now come with 8GB DDR4 RAM -that is A LOT. Seems resolution also made a jump from 1024x600 (pretty good but pegged at this for a long time) to 1280x720 QLED on the higher end units. If the xda-developers.com community uses it, who am I to argue. Another key step is to root it. Since the OP mentions adding a raspberry pi and identifies the ribbon connector type, I think he/she knows the electronics/programming well to make a decision.
Below is an example of a Seicane unit to highlight the specs that the BUYER would need to look out for. They tend to be over priced but have a direct channel for support-YGWYPF. Joying is another respectable but expensive (double the cost) name.

another example with specs (bezel is not for this car)
Don't use Wish.com (or DX.com), they are the equivariant of an online Dollar Store. Look at Alibaba.com (China's Amazon) or Aliexpress (owned by Alibaba) OR just buy from ebay or Amazon b/c they may have it in US warehouse for quicker shipping and possible free returns.
Sorry OP for going off-track. Let us know what you decide to do and update us with the final product. FWIW, this was discussed in the past but I couldn't recall the post. Another Euro member investigated it and the resolution was bad and ended up stickling a tablet in there. If you search hard enough you should find it.
EDIT:
No one manufacturer has a monopoly in this industry, and the units are universal, only the bezel is unique to the car.
