Not sure what anyone's problem is, I'm running it on my Touch Pro using DCD's 2.16, and its working. Not as well as I had imagined, but I'm not speaking loudly (in my office), so maybe it will work better in my car.
I saw some folks say it wasn't working, so I poked around and it seems to have a lot to do with .netCF, so I found this thread:

Funny thing, with DCD's rom, it wouldn't let me install that CF (said it was older than a currently installed one, and the current one would need to be removed first).
But, I figured what the heck, try installing the application anyway... And it seems to have worked. Go figure.
Not sure if the one linked there is somehow different from the one linked here- I only tried that one.
