Word of warning though(at least with my model)...the unit is updatable...and you get the newest maps they have to offer if you register and update it within a month...BUT and here's the rub....IT DOES NOT COME WITH A CABLE TO CONNECT IT TO YOUR COMPUTER!!
The upside is that if you have digital camera the cable that came with it should work with the GPS.
no matter where you are. . .even if you've never been there before in your life. . .if you need gas, food, some place to sleep, some place to take a squirt, a detour around a section of highway that's been closed by an accident, etc. . .the answer to your question(s) is only a couple of touchscreens away. . .these things rock. . .
