TeleNav, VZNav or Garmin for VZ BB Curve?

TeleNav, VZNav or Garmin for VZ BB Curve? Which one does everyone prefer and why?

amAzegps.com, because it works in Australia and it's free ;) UI is a bit clunky but ok.

Actually I would like to hear some pros and cons on the three listed above. I am not opposed to paying money for it, I just want the best that is out there. I would assume Garmin is good since GPS is what they do, but I heard TeleNav is pretty good aswell. I have VZ naviagator and i think it kinda sucks. Anyone out there have thoughts? Thanks to Delta Foxtrot but, I'd like to hear from some people in the US just to compare.

I've heard of some people using bookmidlets to turn google routing info into GPX route files instead of their garmin because google had better routing.

The Garmin is nice. I tried the 30 day trial, but it couldn't keep up with me when I missed a few turns. My standalone worked better.

I am trying out AT&T Nav which uses TeleNav and it's nice, works quick.

I haven't used VZ Nav.

I would try some of the free ones as well:

Another vote for aMazeGPS. Free and works great with spoken turn directions. Works great with accuracy where I live. NerthEast US. One thing is that the starting up of the application is slow. And entering address is also a bit slow. But, hey it's a great free app.l
