LOL - I am 2 months late in replying to this so accept my apology for this first off.
Secondly, I am using S&T 2006 w/gps locator in my 2006 Scion xB. I have it mounted to a laptop which sits right in front of my temprature controls and stero head unit.
At a red light, i'll quickly punch in the destination, and in seconds I have the route ahead of me. I don't know what you meant by it being worthless, but to me, it's very useful. I know you can't use ALL or EVERY SINGLE feature while you're driving but just having a heads up map and rout outlined to me is worth the price.
I paid $104 from amazon a couple of weeks ago for it and it's incredible! I reccommend it to anyone on a budget.
Go into a sports bar and ask who the best football team is.
You're going to get ****loads of different answers. Same here.
Personally, I use iGuidance. I like it. I've used S&T and don't like it for use in the car.
Some people prefer Destinator or one of the wrappers for it (MapMonkey, FreeDrive).
Some like the michilen product or Alturion or the apps that were included with their GPS units.
I don't think any one is the best. I merely have a personal preference. My preference may very well change if I find something that works better for me.
Have you looked in the FAQ yet?
How about the Wiki?
