This becomes stressful when you’re driving alone in a strange territory. However, having someone with you won’t help either sometime, because more often than not, your companion would end up confusing you more than helping you navigate the road.If you think it is the map that is causing you your problems, then better way go get a new car GPS receiver and use it instead of the map.

GPS device is a GPS receiver especially designed for cars and their navigation systems. A navigation system in your car possible by GPS of satellites and signal they send down a GPS receiver in your car.This GPS system enables the of driver of the car find his way to certain destination out via route mapped by the navigation device.The GPS gives you your position according the coordinates established by satellite feeds,however it is only with the use OF A digital map Of the streets that the GPS navigator CAN show you your position in relation ton your surroundings.

Basic features that all car GPS devices must have are:

- Map storage system

- Screen or display that can handle images of more than 320×240 pixels in size at a resolution and brightness suitable for driving.

- Address book for storing frequently visited addresses and points of interest

- Detachable or external antenna for better GPS visibility

A vector map serves to provide the content for the road database, which paints out the detailed street grid of a particular area from which your car GPS system can calculate your optimum route from point A to point B. Street names and addresses are used as points of reference.

Built-in or fixed car GPS devices can usually be found only on brand new luxury vehicles. As such,if you don’t have the cash to purchase.This can be the best option because the GPS device is already integrated in the vehicle’s system. This removes all of installing the car GPS device on the vehicle and loading additional navigation software on the system.

Purchase a portable car GPS device. For this type of car GPS device, you are again given two options: a portable car GPS preloaded with maps option. It also costs higher than portable car GPS units that requires map transfers option which you can transfer map data from your PC to the device.

Try in the store if they have a good return policy if it does not perform the way you want it. I suggest Amazon.com you can read GPS reviews and compare price&model feature.
