The screen display occasionally (once or twice a quarted) goes blank or freezes. If I turn off the car and restart. the problem goes away. Now, the auto bluetooth will no longer connect to my phone. I think the two are related and the problem is the systems computer.
You’d probably be best served by taking this to an infinity dealer.
No question… just an answer. I agree with @old_mopar_guy, to the Infinity dealer for diagnosis.
