Lou's GPS Systems

Garmin has produced a new must have unit for those of you who already own a Garmin gps (global positioning system) product.  The Garmin gps mount will improve your traveling experience by holding your gps unit in place.  Many times when I am driving, my gps unit will slide all over the dashboard and sometimes fall on the floor, especially when making wide turns.  The Garmin gps mount has fixed this problem for me and I am positive that this unit will fix this issue for you.  

The design of the Garmin gps mount is thin and sleek therefore it doesnt take up much room on the dashboard.  The Garmin gps mount is also very secure because the unit posesses friction mount that keeps it in place even when making difficult manuevers on busy city streets or on crowded highways.  The base holds the mount secure to the dashboard by gripping it tightly.  Your respective gps unit can be secured easily into the mount.  The mount includes a ball attachment so you can easily adjust the mount to the best angle for you.  This way you can easily view the screen and can make changes in destinations or routes while driving.  Some of the models are attached by a bean bag and some even have a suction cup that attaches the unit to the windshield.

The Garmin gps mount is portable which is a very important feature.  The unit can easily be removed from the dashboard of one car and can be secured onto the dashboard of another car.  The unit works on almost all vehichles and specific mounts can be purchased if your car requires this.  The Garmin gps mount also includes a arm that can be folded down and stored in your car.  This unit is compatible with almost all Garmin gps units including the nuvi series and streetpilot series.  However there are some mounts that are specific to certain Garmin gps units.   

The Garmin gps mount is a great buy and the unit is useful for cars, bikes, and boats.  You can read reviews on the Garmin gps mount and buy this product on learning-about.com/garmin

how does the personal gps system work such as garmin, tom tom, etc.?

I am familiar with the basic theory of the reception of the satallite signals to locate a spot on the earth. I am interested in knowing how the actual car equipment stores so much info and how the directions are created. In addition to the actual map routes being loaded, how does the system know if the road is 4 lane or 2 lane and where the crossovers are on a 4 lane. How does the system know where turns are not allowed, etc.

Answer
Garmin uses Navteq navigational software to produce maps and directions. The map/roadway information is stored and the directions are calculated using this information. The information is compiled using satellite imagery and highway information built into the software. The software looks at current position, destination and available roadways between, applying logial analysis to determine the best route. This is why the GPS units can recalculate on the fly, because they look from where they are, not where they were.
