Premium features ALL disable when car is in motion. Navigation, Phone menus, etc.
I would NOT have purchased the car if I had been informed that I would have to pull over to the side of the road to use the touch screen menus.
Poor Driver Experience.
I will NEVER own a Lexus again and will tell everyone NOT to buy a Lexus. All because the features I needed the car to have do NOT work with the car in motion.
It's there for safety reasons. You can disable that feature very easily. You have to do a special sequence which gets you into the service menu, from which you can de-activate it.
Google is your friend :)
You should do some research before complaining about this fine car. There are work arounds.
Don't blame the manufacturer- I'm pretty sure that is a legal requirement to disable features which would distract the driver when in motion.
