Best Gps Receivers

GPS Receivers are becoming more and more versatile. A modern GPS unit can do all manner of things apart from merely telling you where where you are (which street or coordinates), A GPS will tell you how far away from you vehicle you are, tell you in which direction and what speed your dog is moving (or your auto that your teenager borrowed for the evening). It may also be able to tell you when the sun will set, which way is north and how high above sea level you are. It talk to you telling you which direction to go in and confirm when you arrive. It will play music: suggest a route which avoids traffic congestion or severe weather. You can use a GPS to record your vehicle's mileage for tax purposes and spy on where your employees or spouse takes the car after hours.

With a proliferation options its therefore important to decide what is important for you and what is not.

Consider some of the following:
Weight - if you are carrying the unit weight is critical
Battery Life - how long can your GPS unit last on battery power - hopefully at least 24 hours. A bright large screen is nice in a car which is plugged in but it drains battery power.
Water Proof - water proof units are also, by definition, dust proof too. Even if you aren't boating you need a unit that is water proof.
Size of Screen – a larger, brighter screen is important if you want to view your real-time map: but remember it will consume a lot of battery power so
Adaptors to power off your vehicle – make sure you can get an adaptor and cradle for your auto GPS unit which will position it correctly on your dash and allow it to charge via your cigarette lighter or similar.
Maps – if you want specific maps or marine charts check these availability and cost prior to purchasing a specific model.
Data Services – to receive real-time alerts when a vehicle moves outside of a pre-defined area or speed you will need to subscribe to a service. Also if you want real-time traffic conditions and weather check on availability in your town and for the model of GPS receiver you are considering.
