Actually...most of the stuff I've read says the mouse was better.

You do know the RTC on your GS has up and down buttons above the mouse to scroll right? Just move your finger up and use that rocker switch to scroll up and down.

 

Idk if you've tried it yet, but it does not have that functionality of scrolling (2-finger setup like MacBook) or writing capability (for English). It's a lot of guessing where the cursor is going to go. Plus the touchpad doesn't have scrolling buttons like the mouse controller.

Audi's system isn't just a trackpad though, it's mostly a **** and buttons interface with some touchpad functionality. I like the Audi system the best, but I have friends and family who find it confusing and hard to use. They tried my Lexus system and picked it up quickly.
