I use both on a weekly basis. The wife's 2016 Acura RDX (was mine) has the navigation / technology package. It's 2 screens (no idea why) where 1 controls the radio, phone, settings and the other is full time dedicated to navigation. It's often gotten confused where we actually live (there is another street with the same name a few towns over), it's slow; it often wants to take us on a less then ideal route and who knows the last time it was updated - probably never because I'm not paying the $400 / year for the service. VS on my 2016 Mustang which Ford was kind enough to send out an update for Sync 3 + an $80 USB module upgrade to allow the car to have Carplay. I get in the car, plug my iPhone in, turn on the car, the center console immediately flips to Carplay, begins to play whatever music I left off on and Apple Maps is 1 touch away. I can tell Siri to route to where I need to go or look it up quickly. The map is always up to date; shows traffic and is quick to the touch. I'll take Carplay over anything on the market right now. BMW charging monthly / yearly for it is bull but if I had one, I'd probably pay. I like it that much. Naively, this is the 2nd Acura we've had back to back without Carplay and now that I use it daily on the Mustang, there will not be a third. The next car has it, or we don't purchase / lease it.
