When navigating (using google or waze maps) and HUD is showing image and street names direction, connected by usb cable. if suddenly disconnect the usb cable from the phone, AA will return to mzd menu but HUD will be completely frozen on the last image/street name and can not be turn off or reset. The only way is to reboot the infotainment system.
I had also tried reconnect usb and set new route while the HUD is frozen but HUD will not show new route as it is still stuck on previous image.
