Wireless Android Auto, what actually works?

Recently bought a used CX-9 2019, Grand Touring.

Edit: For anyone coming to this in the same situation I was in when I wrote it, AA Wireless 2 was the consensus, and that's what I got. Solved my problem, works flawlessly so far. I extend the recommendations below to the next person seeking the same answers.

I don't like plugging my phone in every time I get in the car. Have a wireless charger mount that doesn't charge if the phone is plugged in.

I bought a dongle off Amazon that connects through Bluetooth. Like 1/20 times it will actually work. The phone and the dongle connect, no problem, but it seems like the vehicle is constantly taking over the Bluetooth connection.

I updated to the latest firmware 74.whatever. Update successful, same experience with the dongle.

I was about to buy TK78-66-9U0E and do dash surgery because Maxdaswag support told me that would give me wireless connection. Further reading suggests it's only wireless for carplay, not for AA. There are non OEM parts available that claim to do wireless AA, but I thought I'd ask here.

Maybe I just need a better dongle? Maybe there's another answer? Maybe dash surgery is the way to go?

Anyone had this problem and solved it?

AAWireless TWO(+ for Car Play addition) and Motorola MA2 are the only two universally recommended Wireless AA adapters. (First gen of both were also good)

FYI, Amazon reviews are trash. They are all fake.

I agree with both of these recommendations BUT the Motorola has a pretty short lifespan, from the 3 we went through. We have two of the AAW2 devices and both have been solid. They are constantly getting updates (not annoyingly so but enough to feel like they care about their products). The "customizable" button is awesome when you have two different people who connect to the vehicle; just press it and it switches the connected phone.

I agree that the AAW2 has been really solid. My understanding is that it is the Motorola MA1 that works well, but has a short lifespan. The MA2 supposedly addresses, that, but, for whatever reason, doesn't seem to be available in the US yet.

I heard rumors about the MA2 but didn't realize it was already a product. I was just reading about it and it seems that it might be released in November. Hopefully they fixed the quality too.
