Driver Navigation System Promise And Reality

Driver Navigation System Promise And Reality



Driver Navigation Systems - Promise and​ Reality
Automobile navigation systems have been with us for​ a​ while now, and​ every year it​ seems that new features are bolted on to​ the​ various systems .​
All of​ them are based on GPS, or​ global positioning systems .​
Simply put, the​ device interacts with a​ satellite that establishes, with varying degrees of​ accuracy, exactly where you are .​
Depending on the​ system, it​ uses DVD for​ backup information or​ other software that has specific geographic information on it​ to​ determine your location, right down to​ the​ street corner.
There are a​ number of​ GPS systems that are sold as​ individual hand-held devices, and​ there are even some phones with the​ feature built in .​
But for​ automobiles, virtually every manufacturer now installs them as​ an​ option .​
Many of​ them are provided by major electronic manufacturers as​ OEM items.
A GPS position - that is, your spot on the​ planet - isn't much good unless the​ device that is​ providing that information can put it​ in​ a​ framework .​
That's where some of​ these systems are better than others, and​ where the​ breakdowns often occur .​
a​ typical automotive GPS will have a​ small dash-mounted screen that shows your position on a​ map .​
It's critical that whatever source is​ providing that map be up to​ date - perhaps the​ most common objection heard from drivers with GPS systems supported by CDs or​ DVDs.
Many of​ the​ systems today allow you to​ input your departure point and/or destination and​ will then provide you with driving instructions along the​ way .​
They will also provide you with information about gas stops and​ hotels along the​ route, along with information about points of​ interest across the​ country .​
Generally, the​ newer versions of​ this technology manage to​ stay up to​ date through downloads .​
One of​ the​ difficulties, however, can be a​ decision to​ detour .​
That may mean a​ major reprogramming headache and​ for​ many cars, the​ entire system may need to​ be turned off.
The General Motors OnStar system has been in​ operation for​ several years and​ has provided navigation assistance along with other remote features including contact with an​ OnStar employee in​ times of​ emergency .​
Their latest navigation methodology provides turn-by-turn instructions taking you through your course from departure to​ arrival .​
In this case, the​ specifics on directions are downloaded from the​ OnStar service .​
a​ driver pushes the​ OnStar button, and​ then tells an​ OnStar operator where he or​ she is​ going .​
The appropriate directional information is​ downloaded in​ a​ matter of​ moments to​ your car's GPS device .​
The directions are displayed in​ text on the​ dashboard monitor, and​ there is​ also a​ voice prompting you to​ make the​ correct turns .​
The problems? With this system, the​ OnStar operator needs to​ begin providing your programming with an​ address .​
So you'll need to​ know the​ street number of​ that Holiday Inn you're departing from .​
There are also occasions when the​ operator isn't going to​ find a​ site in​ the​ database, either because your information is​ incomplete or​ theirs is​ .​
If your plans change with the​ OnStar system, it​ will simply tell you that you've left the​ route until you once again contact the​ OnStar phone center and​ have them reroute your vehicle.
Pioneer Electronics has been among the​ principal providers on in-dash navigation systems and​ their new products will combine features of​ navigation, entertainment, and​ connectivity for​ maximum consumer appeal .​
Their navigation system has its route guidance information embedded in​ the​ unit and​ includes nearly 11 million points of​ interest, voice prompting and​ mapping .​
Their handheld version of​ this device includes entertainment features and​ wireless connectivity.
