I'm not familiar with the unit that you are looking at, but I have used GPS for navigation. I have a Garmin Streetpilot unit that I use on my motorcycle, and sometimes in the car. They are excellent devices, but are only as good as the map data that is stored in them. If the data is out of date or incomplete, it is not much good. I have map sets for Canada and US that I can load onto data cards. They are extremely detailed and accurrate right down to street adresses. The unit I have does not do the auto-routing very well, but newer units are much better at it.
Another option you might consider if you have a laptop you can use is the Microsoft Streets and Trips software with the GPS reciever. It plugs into a USB port and turns you computer into a moving map GPS unit.
