I shouldn't have been insulting, thanks for editing it out.
I feel the rest of what I said still stands though.
Good stuff. This is the kind of stuff that *should* be done more. Although I hope you do it without taking your eyes off the road; keeping your eyes on the wheel doesn't sound like none too good an idea either :-)I use the Space Navigator knob. It allows me to change audio sources and select different stations/playlists/songs/channels/etc. without taking my eyes off the wheel.
