I be very interested when I learn that there be product that allow the integration of a street map atla with a gp and laptop computer . sound like a excellent tool for travel . after explore a number of option on the web , it appear that the Delorme Earthmate with Street Atlas USA be the way to go , although I read as many bad review as good . the price be certainly reasonable and I decide , why not ? I must say that after two day of see what this thing can do , I be truly impressed . the Street Atlas be a breeze to set up and I love the feature that allow you to copy region to the hard drive , so this thing will run san CD . the include Earthmate GPS amaze I for its diminutive size and good construction , as I appreciate the inclusion of the rubber foot and rubber strip around the unit . within 5 minute the GPS have initialize and I become a green dot on the map show my neighborhood . I immediately jump into the car and wathch my progress on the screen as a friend drive I around town . the accuracy amaze I . then I get serious to see what this unit could do . if I have to make a negative comment , it would have to be the lack of instructional material . two -lrb- tiny -rrb- booklet come in the package that do little more than explain the setup . there be a tutorial build into the program , but it do not have the same functionality as a reference manual . however , if the lack of documentation be help to keep this package at this steal of a price , then I be all for it . after three-and-a-half hour of playing , I have a good handle on all of the feature of the software and be ready to plan my first trip . there be a great deal of information available on these map , include restaurant and lodging and service available off the various exit on the highway . you can enter the name of a restaurant , and Street Atlas will locate it for you on the map . you can then take the laptop\/gps combo in the car , and it will give you real time verbal instuction as you be drive . Pretty cool ! some of the `` point of interest '' be not in the right spot on the map , and some be long go , but I can not fault the software for not know that the pizza place at the shore go out of business six month ago . all in all , it be a package that appear to do what it be design to do . whether or not it be practical in the long run to have all this equipment run in the car -lrb- you can swap the laptop for a smaller device -rrb- have yet to be determine , but my first impression be actually beyond my expectation .
