Well unless the dealer forced you to purchase a non-nav 350, next time please review the window sticker carefully. Anyways at this time, regardless the current generation does not support android auto or carplay. Your options are:
live with a dash mount for your device
Search the interwebs, there are owners who have added on an aftermarket box that basically mirrors your phone to the current screen.
See if you have a cool-off period where you can return and maybe return the vehicle (very few places have this).
