How easy is using the mouse? Can you easily adjust radio and temperature controls without it?

The mouse is very easy to use... once you turn down the sensitivity. Also I find if you grab it with the tip of 2 or more fingers instead of the whole hand like you do a normal mouse it is far more precise. Also many voice commands... but they are different from last gen Lexus's so it takes some getting used to.... I love the way you can give voice commands to play by song or artist if you have your music plugged into the USB port. I use a 16gig thumb drive for music and it is a PITA on my wife’s IS350 to find the song or artist you want scrolling 6 at a time... you can also use any Ipod, Ipad, Iphone, USB hard drive etc…… Think of having 3 terabytes of music, movies, album art etc as you drive…

I haven't gotten my GS350 yet - but I'm pretty sure you can manage basic radio and temp controls without using the mouse.
