Adjusting the sensitivity of the pad really makes a difference. I really don't have issues with it anymore. The nav screen size isn't a big deal to me, it's not like I'm trying to watch a movie on it......although my friends LS screen is pretty damn sweet LOL. I've been looking at the new 911 GTS and the you have to look down to watch the nav screen.....both of these cars will show you a turn by turn on the instrument cluster, so again it's sorta not a big deal to me about screen size.
