I've used Garmin, Tomom, iGuidance and iGo on the TP and if I had to choose among them I'd probably go with Garmin. The last ppc version of Tomtom is old (2006?), iGuidance isn't finger friendly enough, iGo is slow and a bit buggy. I have Sprint nav on my phone and I use it occasionally for the traffic and if I'm in a car without a nav, but I use a cheap (>$70) Pharos PNA a my go to GPS. My main reaon for not using this phone as a nav? The speaker volume is way too low (even w/audiopara tweaks), the screen is a bit small and it's not reliable. It's almost inevitable that just when I'm at a critical and confusing part of a trip the phone will ring or some alarm will trigger putting the nav in the background. If you shop wisely and don't need the newest features, you can find a decent PNA, even Tomtoms and Garmins for well under $100. They will easily blow the phone away in screen, sound and reliability.
