The current ES350 is: Beijing Siweitu New Navigation Information Technology Co., Ltd. (self-made map)
Functions: guiding, searching, reading and storing records and information, as well as voice recognition function, reversing image, whole vehicle radar. ...
Specific: For example, if you want to go to a place and enter a name, the map will show various paths from here to there, including high speed priority, distance priority, time priority ... including arrival time. You can choose a route or search for other routes again; Whenever you encounter a turn (intersection or interchange), it will have a voice to remind you that it is time to turn left (right) next.
You can store the location of your home. Every time you say' go home', when the computer recognizes your voice (this is speech recognition), it can guide you home.
There is also a Bluetooth mobile phone, which is the most practical. The mobile phone is connected to the car computer by Bluetooth, and it will be automatic every time you get on the bus. It's really convenient to make or answer the phone directly without using your mobile phone in the car.
I can't finish talking about more functions. I think you should learn more from Lexus 5S store.
