How to Update a Portable GPS

A GPS, short for Global Positioning System, is an electronic navigation aid used to help you get to locations. Out of the box, a GPS comes with a map that is bound to become outdated as street names change, roads close and venues are added or shut down. Most popular GPS manufacturers such as Garmin, TomTom and Magellan release annual or biannual map updates that include geographical changes. Having the most up-to-date GPS helps ensure that you get where you want to go.

• 1

  Install the software that came with your GPS device (such as TomTom Home or Magellan's Roadmate). You also can download the software for free at the GPS manufacturer's website.

• 2

  Connect the GPS device to your computer using the included USB data cable when prompted by the software. If necessary, insert any applicable memory card into the GPS's expansion slot.

• 3

  Navigate through the software to find map update options. Most GPS programs will tell you whether you are using the most up-to-date map. Some programs might require you to manually check by navigating through an "Options/Settings/Preferences" menu or by clicking a "Download/Update" button.

  Apply the update. Some GPS models, such as select TomToms, offer one free update with the purchase of the GPS. Click the "Download/Update" button to apply the free update. Other GPSs require you to pay for map updates. If you have to pay, go over the details of the map update and enter your billing information into the software. You also might be redirected to the GPS manufacturer's website. When prompted, download the update.

  Wait until the map update is applied. Map updates usually are quite large, often exceeding 2 gigabytes, so be prepared to wait for more than an hour or more depending on your internet connection. After the update is applied, the GPS will reboot itself. You then can disconnect the GPS from your computer and use it.
