How to Install a Car Navigation System

If you are tired of buying, storing and using road maps, you may want to install a car navigation system. Global positioning systems, or GPS units, have come a long way since their inception, and it is easier than ever to install one in your car. The hardest part will be deciding which one you want.

Things You'll Need

  • GPS unit (with mounting instructions)
  • basic tool set
  • Research which type of car navigation system you wish to purchase. There are dozens of brands, models and price ranges. The most popular in-car navigation systems-and often the best value-are portable, meaning you can remove them from one car and use them in another.

  • To begin installation of a portable or "plug-and-play" car navigation unit, consult the owner's manual. Most of these models require very few tools and very little modification of your car.

  • Decide where in the car you wish to place the unit. A dashboard location gives the GPS antennae a clear path to the sky. Make sure the power adapter cord for the unit will reach to the cigarette lighter in your car.

  • Mount the base of the navigation unit to your chosen location. Many models come with a suction cup windshield mount. Others come with a weighted mount that sits on the dash, but could move around during sharp turns or sudden stops. The best bet is to use a mount that either bolts to the dash or comes with a strong, but removable adhesive.

  • You can buy and install additional mounts for other vehicles in which you wish to use the navigation unit.
