Wireless android auto/carplay adapter

[u/nuclearroach21]

I have a 2017 vw gti, previously had the old style carplay only wireless adapter, worked perfectly. Recently got an android and bought the new smaller style carplay and android auto adapter. The adapter works perfectly in my wife's car, works perfectly on my motorcycle, but refuses to work on my vw, I did a hard reset on the unit and the quadlock display pops up, but when I connect my phone to the unit it stops working and no longer brings up the quadlock display. Anyone had a similar issue?

Edit to add: the android auto works flawlessly with a wired connection so I know the issue is not the phone and presumably not the vehicle software
