Gps Has The Potential To Impact Several Aspects Of Day-to-day Life

摘要

Before a consumer buys, he/she usually has to make a decision between a dedicated GPS device (either a QPD PDA or PND) or a phone with built-in GPS. What would you say are the pros and cons of each? Dedicated GPS devices have a specific applicability, i.e. navigation. This works well when Installed in automobiles. Most dedicated PNDs are "on-board" navigation devices, where, depending on the region where they are used, users will be able to buy SD cards with map data. Dedicated PNDs lack the benefit of having real-time information provided to them such as real-time traffic, route congestion and alternatives, etc.
