2010 Lexus RX350 Q&A

2010 Lexus RX350 Question: Car was purchased with Premium & Navigation Package

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. -
Answer 1
That does not sound normal. Brand new car, so I'd take it back to the dealership and talk to them about it. -
