Hi, I have just bought a UX (2019) ex demo. My Lexus info gives me my ID and tells me my sat nav is a 17CY. When I put a search for info on how to use it, it brings it up the nav as a premium model with the 10 inch screen. Mine is a basic 7inch screen, would appreciate if anyone can help me out on this. Have I got the wrong model in my car. Love the car, previously had a CT and before that numerous BMW's. Much prefer the Lexus. Chris
