I think most of you are missing the point in regard to navigation. Many of you have mentioned using a paper map and not relying totally on any computerized navigation system. So what's the point of using Google Maps or any other navigation system if you can't depend on it? You should either use a navigation system or a paper map. Using both becomes combersome and it defeats the purpose for going electronic. I bought a GPS unit because I wanted to go 21st century and do away with the large maps and the mess associated with them. Besides, it's a lot more dangerous trying to read a map while driving down the road, then following turn by turn directions.
Let's make sense here, go electronic or go paper, but don't insist on using both. It doesn't make sense and it's self-defeating! However, if you go electronic, let's hope the information is not inaccurate and mis-leading like Google Maps. Maybe Version 4 in Google Navigation will fix many of the problems.
If I am going somewhere that I have never been, I try to research ahead of time, unless I have no choice. Whether that is Google Maps on the browser, Yahoo Maps, or paper maps, or all of them, I want to know where I am going before I get there. If I am using my Garmin, I'll always look at the directions it gives before I leave, so I get a good, general idea of how it is directing me
to go.
Google Street View is fantastic if it is available where I am planning to go - I can see exactly what the neighborhood looks like before I get there.
I often check directions from multiple places before I leave, to make sure that one way streets are marked correctly, for example.
Personally, I am not looking to use my phone as a navigation device for the car at all. I already have a standalone GPS unit, and it works fine. However, I'll be happy to have it in a pinch, if I have forgotten the GPS, for example.
Here, actually, is how I have used Google Maps on the Eris since I bought it. My daughter and her boyfriend made arrangements to meet at a particular place, at his suggestion (it was a shopping mall, located about halfway between us). However, when we arrived we discovered that the shopping mall was under construction and the parking lot was closed. The Eris was able to quickly find a nearby Panera where we could park and meet instead. The Panera is new, so it was not in the Garmin at all.
Last summer, when driving home from the NY area, my wife made a wrong turn at an exit. We didn't have the Garmin with us, but we did have paper maps of the area in the glove box, so it was pretty simple to find a way back to the highway.
In short, multiple mapping and navigation solutions are very helpful. I think that we get the idea that you disagree.
