What a terrible design, Zero benefit and dangerous. In order to simply change to a different preset radio station, you have to take your eyes off the road and push 1 button then touch the screen twice and go through 2 additional menus to change to another preset radio station. Dealer agreed terrible design, but said when Lexus notifies they said they don't give a sh*t.

Had I known I would not of purchased the factory Navigation system, which is way over priced anyway, and, forces you to Login every time you start the car, disgraceful.

Update from May 28, 2017: Radio and AC controls integration into navigation screen design sucks.
