Hiya
Lexus Enform is the operating system installed in the latest models of Lexus which consist of different information, safety and navigation services. There is a lot of material online for you to read about it. The best one is available on Lexus's own website. With this system you can \sync your mobile apps, access emergency services, receive latest information articles from Lexus, directions for your destination, traffic updates, road side assistance, etc. I think you have to subscribe to one of their packages after the first year which is free. Thereon, you are charged. Not a bad move for a luxury SUV/Sedan.
Let me know if you need more info, i'll share a link or two
