You're on your way to a huge auto show in a town you're unfamiliar with. As you drive, find that none of the street names appear to be similar to the directions that you downloaded from Mapquest. You don't want to go through this, but since there's no other alternative, so you must stop and inquire for directions. Oh , the humiliation of having to walk into a petrol station and ask the clerk for directions. Everyone hates doing this however, they've probably been forced to do it several times. If you had a navigation system in your car, you might have avoided embarrassment and shame. GPS navigation is a technology that has its roots in the late 1960s. It was in the 1960s that the United States military began developing the technology to improve its efficiency and improve intelligence operations. The modern GPS (Global Positioning System) became operational in December 1993, fully operational capability expected in April of 1995. The technology has been available to the general public since the late 90s , and every day there are new items available for sale. There are navigation Navigatie auto updaten systems available that are portable, built into your car, on your cell phone, etc. This technology is really getting popular and a portable navigation device can be purchased for just $200. That's which is a bargain for the ease of usability as well as the ease of use. There are numerous options on the marketplace today. You have your choice between portable units that can be used in the car, or any other location you want as well as an in-dash unit with a TV-screen to display the map. Many aftermarket radio manufacturers offer units, including Alpine, Pioneer and many others. If you decide to use an in-dash navigation device, the cost will rise significantly, starting out around $500 and up. They are more comfortable, but they come with an in-built screen, with no obstruction to driving, and also no unpleasant wires draped over your dashboard. The in-dash navigation systems can also function as a head unit and can play DVDs CDs, and AM/FM radio. If you're thinking about purchasing a navigation unit for your vehicle it is a good idea to consider. It is possible to purchase a portable unit, that can be utilized in your car or any other location you'd like, or an in-dash unit that uses the video screen to display the maps and directions. On the power button, type in the address where you want to go, and it'll take you there. It's impossible to be lost when you have a navigation system in your vehicle since the system keeps updating and if you take a wrong turn the system will create a new route to get you back to where you first put in the location you'd like to go. Many units will also give you verbal directions, giving you the exact location to turn and walking you through the entire journey. GPS systems also generally have already loaded information about nearby places of interest and attractions which include restaurants, hotels rest stops, and so on. The system may even include the phone numbers and addresses of these places to make your trip run more smoothly. I recently went on a weekend trip with my portable navigation system. The convenience of not having to keep checking your directions and being able to rely on the navigation unit being right saved me lots of time and stress. It is possible to plan a trip on the fly and not print out directions to multiple destinations prior to leaving for your journey. It's also helpful in situations where you're looking for places to eat, or to sleep and you don't have to go around looking for something. A navigation device is a piece of technology and once you have one, you will not want to ever be without one again! !
