Talking about GPS buying tips we will start from such function as USB. USB allows you to use external storage media (external HDD, flash drive). In addition, with the help of the USB interface it is easier to create communication with a PC or PDA, and this in turn provides a connection of the internal memory of the navigator (ROM) with information on your computer. Depending on the amount of ROM, you can copy the music, photos, and movies on the GPS navigator and enjoy the ride.

Talking about GPS buying tips it should be noted that not all the navigators are able to play audio, video and view photos. Cost model does not know "how to do it". Model of mid-market price category, as a rule, can play all standards of audio. Watching videos is available only in expensive, best GPS communicators with powerful processors. You should also pay attention on such thing as number of points in the track of GPS navigator: Track - is the passed path. The greater the number of points in the track, the longer "trail" remembers GPS navigator. For what do you need it? In an unfamiliar area it is better to know than not know whence you came, when passed there is something there, somewhere to turn, stop ... and it all possible with help of track of GPS navigator.

Talking about GPS buying tips it should be noted that most users do not take advantage of features of tracks, but it is very useful always to have such a function in your GPS. Experienced anglers use a function of track for the visibility of routes and maintaining the most "fish" places.

GPS buying tips and active time of car GPS navigator: Requirements are less critical than for pocket or travel navigators, but all the same car navigator must be able to work off-line for at least 5 hours. In addition, we must remember that listening to music, viewing pictures and, especially, listening to the GPS navigator will faster discharge battery of the device.

Fortunately, in the car they can always be recharged. Recently, manufacturers started to offer the market a device with two AA batteries. Also, in the market there are many models of devices with 4 elements of AA. The manufacturers now claim that the latest models of good GPS-navigators are able to operate on two AA up to 30 hours and it is very good of course. If this is true, then there is no sense in using the navigator on the four elements at all. Although at this time there was not carried out sufficient testing to confirm long-term operation of GPS navigator on two elements.
