Garmin Quest GPS Question

Jason Boggs

I just purchased a Garmin Quest GPS and have been fiddling with it the last couple of hours. I have noticed that it does not have as many roads on it as some other mapping software such as Street Atlas 9.0 and so on. Will I be able to get mapping software for this that will include more detailed roads or is this it? If this is it, I will be paying a visit to Best Buy to return this puppy.
It came with a City Select North America CD but for some reason it will not install right on my computer. I'm about ready to give up. Any help would be appreciated...
