Do you travel often and take your laptop everywhere you go? A GPS for your laptop may be just what you're looking for.

GPS capabilities are easily added to laptops. You’ll need a GPS receiver. These are small units that attach to your dashboard or windshield. They connect with your laptop by USB or Bluetooth wireless.

Many GPS software packages come bundled with receivers. These feature-rich bundles often run less than $200.

Let's look at some of those laptop GPS packages and how they can help you.
