All GPS navigational systems function by communicating with satellites in space to provide users with the most accurate location information possible. Although the satellites are accurate, the maps on your GPS may not be. New roads are being built every day, while old routes may be renamed or blocked off altogether. It is imperative that you periodically download map updates for your Sony GPS to ensure that your equipment is accurate before taking a trip.


Step 1

Visit and log in. You must be logged in either as an administrator or a user who holds administrative rights in order to download and install new files to your GPS.

Sony offers a program called “Download Taxi” that will allow users to download and install multiple program files from the website at once.


You may only use the Sony U.S. website to update products that were originally purchased in the U.S. or Canada. If you purchased your Sony GPS in another country, you will need to download updates from the Sony website specific to that country.
