Pros.. 1. GPRS is a handy tool for drivers who can use it. 2. GPRS is definitely much above just Maps/Guides or Touristic directions which one seeks and follows when travelling in unknown places. 3. GPRS provides for location presentation on a spredsheet and gives a distance and sense of direction one needs when planning travel. 4. It is handy assistance while manovering turns and taking different roads. 5. It provides help in advance when travelling and alerts if a wrong turn or direction is wrongly chosen. 5. It travels with you. 6. It minimises dependence on checking from unpersons who may know or even are ignorant and some times pass wrong information. 7. GPRS is a guide and can be updated whenever the same are available from suppliers.
Cons.. 1. It is costlier and beyond many persons budgetary reach. It requires either a car ownership or a mobile or a Viewing System. 2. In India thereare too many roads and too narrow by lanes. Putting them all on the map will make it more confusing when viewing. Only it may be helpful when driving thru vocal support. 4. It is an irritant when the speaker keeps repreating same plan and argues based on its chartered course and does not correct course if any other optional road is taken for traffic or accessability reasons which are not indicated as inputs to the basic desined plan.
