Uninstalling app doesn't fully remove wireless AA

[menachg]

I tried this app but decided it does not fit.
So i uninstalled the app but the car Bluetooth keep showing up on phones as "wireless android auto available" (verified with a new phone that never connected to see if its phone or car)
This is a problem as it blocks connection I'm doing with am aftermarket aa unit i added
Why does this keep happening?
I tried resetting bluetooth app installed AA apk nad enabled/disabled the developer server option
Tried re-installing to remove data manually
I guess its not app data just once an Android auto connection is established something in system files shows up now as an aa unit
Any clue how to reset this back?
