Here’s another great idea to get a geek (or really anyone) this Christmas. A portable GPS (global positioning system) unit that can be plugged into your car and mounted on the dash. These neat electronic devices can tell from satellite signals where in the world you are and can give you directions! Most allow you to type in a destination address and then the unit gives you turn by turn directions to get you where you need to go. Pretty cool.
There are plenty of options so I just linked a search page on Amazon for GPS & Navigation. Check them out.
