ok , this be my first GPS unit , so I have nothing else with which to compare it . we have just use it for the first time and be very impressed . we live in a very small subdivision out in the country in central Arizona . the TomTom recognize we home location and direct we faultlessly to a destination in Phoenix . as we move along the Interstate , it show all of the cross road and exit number as we approach they . it know the speed limit and the speed we be travel -lrb- talk about Eye in the sky ! -rrb- . it give a arrival time , number of mile to destination , and number of mile to next turn . it announce the turn clearly use street name . despite this , the pilot take the wrong exit -lrb- `` c '' instead of `` b '' - he fault , not the unit 's -rrb- and the TomTom immediately begin give clear instruction to the destination from we new unplanned position . you can ask it `` where be I '' and it tell you in term of street and city and also show the latitude and longitude . the screen map even show little insignificant dirt road lead off the state highway , which could be important if one need to pull off the road . you can also call up point of interest - restaurant ; gas , police , and fire station ; medical facility and hospital and much more . the restaurant information for the town nearest we home be a bit outdated , as several place have close or change name . there be a emergency button to press - I do not know what it actually do , but if I ever have a emergency , I 'll let you know . the next test will be on a yard sale adventure and I 'll find out how well it do find house address in small town . if there be a problem , I 'll update the review . the TomTom do not play music or show family picture . it be strictly a gp unit with a touch screen and that be exactly what I want . I be very pleased with this purchase .
