So I parked my Giulia while on a call initiated with CarPlay. Unplugged the phone and switched to headphones, then turned off and locked the car. However, the infotainment screen did not go off (showed the last Sirius channel I'd been on), even after the the delay for the headlights to go off. Could not figure out any way to get it to go off (unlock/relock. restart/stop). I assume it was because the active call was keeping it on (even though I was no longer using the system to listen to it). Finally tried turning off the Bluetooth, and that did it. Anyone know if this is correct operation? I assume it would have shut off when I got far enough away for the Bluetooth to disconnect, but wasn't able to walk away and return to check. Any insight from the group?
