Summary: This was my mistake: this unit has no battery, so it is only alive when the car runs. If the car's engine stopped and you start it again, your unit will re-initiate. Another inconvenience is that you need to specify the narrow region you are driving in. As you move from NY to MA, for example, you get lost since the two sets of the maps - for NY and MA - cannot be loaded simultaneously.
Summary: This GPS gets the basics done, and belive me I am glad to have it if I get lost, but it does lack on its mapping and finding a location/business. I know for instance when searching for a Walmart when one was close by, it wasn't able to locate it or direct me to it, and it was not a recent build, it was a location that has been around for over a decade.
