We have owned the "Garmin 50" for a few years now, and it got us where we needed to go. In and out of state. It's been pretty accurate.
I just today download the App "MapQuest GPS Navigation & Maps" onto my phone to give it a try. We are flying into Orlando on Sunday and we will be renting a car, so I wanted to pre-test the MapQuest directional knowledge. I lived there years ago so I know of the area to be able to test it's accuracy.
I am impressed, and quite surprised, to see how accurate this phone app is. I like that it shows ( animates ) the course of direction with the voice commands, just like the Garmin.
A definite thumbs-up on this APP.
P.S. I agree, I too, am not fond of the Google Maps. I prefer MapQuest.
