Get lost or arrive late is almost tasteless with all GPS us by the arm. The Global Positioning System satellite, previously reserved for mountaineers, sailors and drivers, has become very popular in the car and even in the phone.

However, there is such a quantity e of models and different card systems, the selection of a device to deliver at Christmas, for example, is uphill battle!
The GPS market is booming.
Also during a visit to large retailers or on a website, the choice becomes very difficult given the large number of proposed GPS.
Before choosing a model you should ask several questions.

ATTENTION to comparative magazine and website.
We alert you to the fact that some paper magazines, specializing in automotive, High Tech, and some websites carry out comparative GPS quite negligible.

Indeed, some do not test products, referring only to information disseminated by manufacturers on the internet. Others make a selection by ranking: 1st, 2nd, 3rd, etc ... purely misleading.

Indeed, this classification is based on purchases of advertising space in magazines, or small commissions made by some manufacturers to the person in charge of the comparison. Therefore mistrust.
In any case, we find abstract achieve rankings for the GPS, because their use will vary from one user to another. Also announce that this or that GPS is the best is totally preposterous.

Currently some GPS are eriti v MFDs. There are GPS DVD DivX, and other compatible MP3 etc. Will you use it only by car, 2 wheels, hiking?
There are currently few brands offering models for 2 wheels, TomTom Rider and Garmin Zumo is the best known. These models are designed to hang on to your motorcycle, bicycle or scooter and resists rain. Vehicle models may also be useful for your pedestrian. Therefore, it is preferable to choose a compact and lightweight.


Navteq is the most widely in the market for GPS alone. Its accuracy and its efficiency is practically identical. The choice will be more on the stroke of heart on their need.
The cards are, for some GPS systems, pre-stored in the device memory (RAM or hard drive depending on model) Some external memory cards (SD card) for storing data.
The 3D display is the most efficient and very pleasant, check if your choice has this function.
The choice of brands is important, best known as Navman, TomTom, Garmin, Magellan ès are very present in shops, but other manufacturers, less known, make excellent products with the same options, see some more options interesting and more complete. You need to know or find you attractive options especially to determine your choice.

Here we talk for example of the MP3 player memory card, the ability to view photos via a memory card. Vons we consult several GPS to know the functions of each and you refer to what will be most useful for your personal use.

In most cases the future owner of a GPS will buy their product through the little nicer to him made, or on the spur of the heart. But beware, even if some products are aesthetically beautiful, their functions are not necessarily as powerful as other GPS less "design."
We advise you to always check the options of the GPS software.
If you have the opportunity, it is best to test the product in hand or to consult tests on websites.
We can only advise you with a GPS screen glare. Nothing worse than not see anything on the GPS at the lowest sunshine reflecting on it.
Manufacturers rely on this easy argument to sell their model, you'll easily this information on product data sheets.

The size is also important. A small screen is quite unpleasant. The minimum for proper use will be 3.5 inches. You are now models with a screen 16 / 9, which is not necessarily more useful than others. This equipment is not an important element when choosing your GPS, it will be more for aesthetic taste.

GPS need weapons technology to work. The chip is the most important component. Thanks to it, information is transmitted in a standard language called the NMEA (National Marine Electronics Association) and most use GPS chip developed by SiRF Technology (Silicon Radio Frequency).

The two components are more recent SiRF chipsets Xtrac II and its latest development: SiRF III (or SiRF Star III), particularly able to detect signals in a closed environment. We advise you however, with a GPS chip SiRF Star III even more effective. Always ask the seller if the GPS is fitted, or see the datasheets on the websites.

CONCLUSION

Before purchasing your GPS please refer to product testing on the Internet, view the options of each product by asking you if you actually used, etc.. The price of GPS is variable. You must make a specific budget and choose your future browser to it, but remember, a great brand does not necessarily have the best GPS on the market.
