It depends where and how often the device downloads the GPS information. Streets and roads are always changing, so the GPS device must download updates to be accurate.
No, nokia is known only for their cellphones not GPS'S... if you are looking for a good gps get Garmen or TOMTOM.
Marine navigation systems are just as accurate as any other navigation system. There will possibly be some inconsistencies here and there, but that is always to be expected with GPS systems.
Satellite Navigation is just as accurate as GPS, having a 1-10 meter buffer zone. Both use a similar system, having satellites in orbit to triangulate a position. Satellite Navigation, better known as GLONASS, is used mostly by the Soviet Union while GPS, is use worldwide and the widest used system.
From the reviews I have read the Nokia GPS Navigation System seems to work fine for the basics like text to speech functionality and traffic information but when it comes to user interface and navigation it could use some work. Overall it is a good product getting an average of 3 out of 5 stars. You can look at some of the reviews on cnet.com
The Global Positioning System, or GPS, is a network of Satellites used for accurate navigation of ships and aircraft.
Global Positioning System (GPS) uses the signals from geosynchronous satellites to provide accurate position information for navigation. As such utilizing GPS for navigation amounts to utilizing satellite navigation ("sat nav"). Note that while GPS, which was developed by the US government is the most widely used satellite navigation system, Russia also has the Global Navigation Satellite System (GLONASS) deployed which can provide essentially the same satellite navigation capabilities - and can be used in along with GPS to get faster and more accurate position information. The EU, Japan, China, and India are also working to deploy a satellite navigation systems.
According to my research the auto GPS navigation is very accurate. This is an article you may find interesting http://automobilegpsnavigation.co.cc/?tag=accuracy
Garmin and Tomtom are both reputable brands of GPS navigation system.
Early in 2010, Nokia announced that they would offer free turn-by-turn voice navigation for all its GPS-enabled smartphones no matter where in the world you are.
Yes all the new Honda City 2014 have the GPS Navigation System.
The Nokia GPS module pretty much equals the Garmin in terms of navigation effectiveness. Nokia's screens are smaller so that is negative when just wanting to make a quick glance, but the Nokia's maps are a bit more detailed.
