However, if, you are one of those city residents who generally rely on mass transportation, a handheld GPS might help you get around your world. Remember that it is difficult to understand satellite signals for the skyscrapers. There must be an apparent view of sky to transmit your signal to and from as a minimum of three of the satellites installed around the globe so as to get an accurate position. If you need the handheld GPS to navigate in blocked, it is better t go for a hard copy street map.
Mostly the handheld devices are small. Installing the GPS unit mean patching up for fewer whistles and bells than you may get in an auto unit. A GPS is only meant to let you know you where you are. Helpful voices, maps and the moving indicators are all additions.
