For years Global Positioning Systems have been used for hiking, sailing, and flying but only recently has there been GPS tracking for cars. Slowly they are becoming more and more common with companies such as TomTom and Garmin paving the way for easy, accessible, reliable, and affordable in-car global positioning. This combined with the prevalence of GPS locater chips in smart phones, and the low cost of a GPS USB dongle for laptops, mobile computers, and dash mounted computers makes having a GPS an easy option for modern road and high navigation.

When looking to purchase a GPS device, one must know what their needs are, and what their needs will be. GPS devices aren’t expensive, but they aren’t so inexpensive that anyone would want to make them a regular or annual purchase. The most common variety is the dash or windshield mounted single unit variety. The can run anywhere from $75 to $575. There is a market price for GPS devices, and cheap does mean cheap, while pricey often means feature full. Important features to note are national maps. Maps on lower end models often are incomplete or outdated and must be repurchased, while higher models offer complete and detailed maps with way-points and places of interest. You must decide if you want to pay a cost upfront for better maps, or what is in general a much higher cost later, for maps as you need them. The flip side is that a lower end model may enable you to only purchase the maps that you need.

Another common and welcomed feature is the ability to broadcast verbal directions on the car radio. Turn by turn directions are a very common feature, but the ability to have the played through the radio inside the car as opposed to the devices speakers is useful. This allows greater volume to combat volume outside the car such as traffic and weather. Like the radio broadcasting, another popular feature is for the device to act as a Bluetooth interface device enabling many cellular phones to be used hands-free, freeing the driver to concentrate on the road in case of an emergency call. GPS devices are like miniature single purpose computers, often with features that that few could even conceive of. The key thing when shopping for one is to know what the common features are, how much they cost, and what you need now and what you may need later. These are amazing devices that are here to stay.
