I think you are referring to the Dash GPS. I haven't used one myself, but it at least looks interesting.

It feels so strange. I keep reading all of these "ZOMG teh crashes!!1one" horror stories about iTunes 8 and Vista, and yet I upgraded to 8 on Tuesday and have had not a single issue with it, my iPod, or my iPhone. AFAICT it even runs a little better than 7 did (granted, purely anecdotal...no testing done whatsoever).

Am I the aberration in this case, or are the vocal minority getting WAY out of hand again?

Hmmm....
