In-Car Navigation GPS Units

Back in the old days, when GPS was new technology (circa 1994) everyone was sure that within ten years every car would have GPS Navigation and most of us would be wearing receivers on our wrist.  Great concept just a little slow to develop.  The main reason is that unlike hikers, automobiles must follow set paths with rules and restrictions.  GPS couldn't really develop without good mapping and cheap memory to store all the map data.

Today, the technology has matured and the it's potential for every day life is widely accepted and enjoyed.  Basic In-Car Navigation units are so familiar that they are starting to become standard equipment for new cars.  Aftermarket units are pushing high-end features like the ability to factor in current traffic conditions (with special receivers and service plans) and BlueTooth^TM interaction with other devices like cell phones.

After market units give the buyer added flexibility of being able to transfer the GPS unit from car to car.  Now you can take these handy units on a business trip or vacation and enjoy the same GPS services you receive at home!
