So I bought an audio unit from a 2022 Touring model to be able to use Wireless Android Auto, but when I plugged it in, the audio doesn't work.
This is what the New unit looks like

And this is the unit I removed

The new unit has a couple extra connections that my unit doesn't use, these being 4, 5, & 6 (same as 3). 4 & 5 appear to be speaker wires so that shouldn't be part of the issue. The unit I bought didn't include a plug for connection 6, and my unit didn't have anything plugged in in the same spot (3), so I assume that shouldn't be part of the issue either.
The discrepancies begin with connection 7 on the new unit. I assumed those were speaker wires as well , and since my unit only has one of those wires (2), I thought just removing the wire from my unit and plugging it in to the new wire harness would be fine. After messing around with that wire some more, it appeared to be related to the AM/FM radio. I was playing music (referring to my old unit here) through BT with my phone and disconnected that connection (2) and the audio continued without a hitch, leading me to believe it may be the antenna or related to it.
Connection 1 wasn't used on my unit, and the plug from the new unit only has 3 wires connected to it, so I don't think that's part of it.

The next discrepancies though are where I believe the issue may be stemming from.
This is the blue connector coming from my car that was plugged into my old unit.

And this is the plug that came on the new unit.

You can see how my connector has a few more pins populated compared to the connector from the new unit.
And it's the same situation with the connection that is to the right of connection 3 (6).
Here is the plug coming from my car

And the plug from the new unit

The blue connection has 7 extra pins that the new unit doesn't, and the other connection has 8 extra pins that the new unit doesn't.
I don't know how these extra pins could potentially be affecting the audio, but since I don't have a tool to remove these and test it without damaging them I'd rather not take the risk.
I tried plugging in that extra plug from the new unit (1) and shorting the wires together in the only 4 possible combinations, but this yielded nothing.
The strange this is though, the unit works perfectly aside form the audio. It has navigation, which my car doesn't, and it works just fine. The wireless android auto works as intended, and it even reads the USB port.
Does anyone happen to have some knowledge on this that could help, or maybe have the wiring diagram? I'd appreciate anything at this point, I really want to make that wireless android auto work.
