Turning the Automated Appointment AcuraLink/Message Screen
preference off will disable
appointment notifications in the
vehicle based on appointments
created or changed at My Acura's
online scheduling website.
Appointments can still be created,
rescheduled, and canceled from the
vehicle; however the appointment
information stored in the vehicle will
not be updated. Any changes to
those appointments should be made
from the My Acura website.
