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.

Difficulty: Moderate

Instructions

Things You'll Need:

• GPS unit (with mounting instructions)
• basic tool set

1. 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.

2. 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.

3. 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.

4. 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.

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

Tips & Warnings

• Don't buy an in-dash or DVD-based GPS unit. These are often difficult to install and much more expensive than portable GPS units.
• Do not mount your portable navigation unit where it may become dislodged and create a projectile hazard.
• Do not install the mount for your portable unit over an airbag.
