My experience is that the dealers have a scant understanding of how the systems in the cars they sell actually work, not helped by the fact that there are frequent software changes and updates. Took me 3 years to find out why I could not get all the functions in my ex demoToyota - it needed a subscription, which also defeated me so I have to hit a cancel button on every trip to save it asking me if i want to set up a connection.
