Better resolution screen. Resolution is crap compared to most other car manufacturers.

 

You should take a look at the 07+ GS's they have Gen5 Navi with VERY good resolution. The resolution on the Gen5 is better than any other manufacturer i've seen.

I would like to see it work in motion and have internet connectivity. It would be really nice if they would come out with a ground breaking iPhone/Pod integration too.

 

I'm referring to the Gen 5 navi. I have a Gen 5 on my other car. If you look at the 2010 BMWs for example, they seem to have HD high contrast screens. Much better than the ones equipped on our Lexus and they have a better looking UI. The difference is much much more extreme than comparing the difference from Gen 4 to Gen 5. If you put them side by side, it'll make the pixels on a Gen 5 look like legos.
