Does anyone have a bike computer that has GPS? I've been reading about the Garmin products and today being out with only me and the cows (who don't give very good directions and stubbornly won't even tell you if your compadres passed thru) made me think about this more.

I see the Garmins have a GPS chip but I don't see that it has mapping functions. It would have been nice to have it tell me that my next turn is 2.6 miles away or something. Or at least give me some function to tell me how far I was from civilization...

Doesn't have to be Garmin. It's just the brand that I know...
