TomTom is a major provider in global positioning systems, and has equipment that ranges from vehicle hardware to handheld devices. Many of these GPS products use a removable memory device such as an SD card to store additional maps and other information. Because the external memory is used on your TomTom GPS, it is important to know how to upload and install new TomTom maps onto the memory equipment.

Plug the USB cable from the SD card reader into a USB port on the computer.

Insert the SD card from the TomTom into the SD card reader, then close out the AutoPlay window that loads on the computer screen.

Open your Internet browser and navigate to the TomTom website. Select "Maps," then "Downloadable Maps."

Select the map you want, then fill out the purchase information and submit the data. The file information now downloads directly to your computer system.

Click "Start," "Computer" and double-click the removable device icon. This loads a window that displays all the maps currently stored on the SD card. Click-and-drag the downloaded maps into the open window. Once the files have finished transferring, close out the open window and eject the SD card. Insert the external memory device into the TomTom's card slot to upload the new map data into the GPS device.
