I picked up a TomTom 130s for $70 from newegg.com and a Ram mount from gpscity.com for $40 for my ST3. I went for a ride on it today to try it out. It's not bad mounted on the clip on. I don't have to tilt my head very much to see it. I can only hear the text to speech if I'm going slow on light throttle. I think the Desmo Times steering stem nut/Ram mount would put the GPS in a little better line of sight. My riding season is about over here. So I won't get to try it out very much this year. I have a TomTom 730 I use in my truck that has line out audio. I used it a couple times in my pocket on the bike, but I think you need to see where you are going. Just text to speech is not enough.
