Car was purchased with Premium & Navigation Package on 2010 Lexus RX350

Below 50mph everthing responds quick on my menu on screen. But about 60mph everything is so slow. Even changing radio stations takes about anywhere from 1 - 2 minutes. Is this normal? I know I cannot use the GPS but everything else is so slow.

That does not sound normal. Brand new car, so I'd take it back to the dealership and talk to them about it.
