I use Tomtom on a Palm Treo 680.
Mine turns the speed display from white to red when I exceed it
(possibly when I exceed it by a certain amount, not sure). Trouble
is, it's *far* too small to even see what colour the text is without
taking my eyes off the road for longer than I want to. I've not
found any way of getting an audible warning out of it.

Have you downloaded the latest software? My latest download introduced an
option under "Safety preferences" to choose a sound for when you go over the
speed limit. I've never actually tried it, though.
