When plugged into one car it shows up but in the other one it doesn't. So I know the obd2 itself scanner is not dead. In the working vehicle all functions are working.

works in 2005 Porsche Cayenne. Doesn't show up in Bluetooth in 2012 Nissan 370Z.

I'm using the same android phone to test in both cases.

Update

I tried with another OBD2 device that I know works (because it works in a 3rd car), and it did not work.

So, I guess the OBD2 port is dead.
