    Initial Troubleshooting

  1. 1

    Install TomTom Home on your computer using the installation disc that was included with your TomTom. Insert the disc in your drive and follow the onscreen instructions to complete the install.

  2. 2

    Plug your TomTom 700 into an electrical socket using the unit's included AC adaptor. The charging light should turn on. If the light does not turn on, verify that the outlet that you are using is receiving power by testing it with another device. If the charging light still does not come on, proceed to the next step.

  3. 3

    Attempt to turn your TomTom on by holding the power button for several seconds. If the device does not turn on immediately, allow it to remain on the charger for at least two hours and then try again. If the unit still does not turn on, connect the unit to your computer with the USB cable and reset the unit by pressing a straightened paper clip into the reset hole on the bottom of the device behind the release button and attempt to turn the device on again.

  4. 4

    Watch the software load on your TomTom. If the screen displays a flashing "X" or freezes during loading, then the on-board software is corrupted. If you have created a backup of your device on your computer, restore the backup. If you have not, you'll have to reinstall.

  5. 5

    Allow your device to complete start-up. If the screen remains grey, then the unit is not properly receiving GPS signals. Take the device into an area with a clear view of the sky and give it five minutes to allow it to find its location.

  6. 6

    Reset your device by pressing a straightened paper clip into the reset hole on the bottom of the unit behind the release button.

  7. 7

    Connect the unit to your computer with the included USB cable if it still does not detect a signal. Your computer will run TomTom Home automatically and prompt you to create an account. Create an account then click the "Update Now" button to update your device's software.

    Reinstalling Your Software

  1. 1

    Connect your TomTom to your computer using the included USB cable. Navigate to "My Computer" on Windows or the desktop on a Mac and double click the icon for your TomTom device. On Windows you will need to open "Folder Settings" from the "Tools" or "Organize" menu, select the "View" tab and click on "Show hidden files and folders."

  2. 2

    Delete all of the files on your device with the exception of the folder labelled "ASR" and any files named after a region, such as "North_America." Eject the device from your computer and disconnect it.

  3. 3

    Open your computer's local document folder, open the "TomTom" subfolder, then open the "HOME" subfolder. Rename the "Download" folder to "Download Old."

  4. 4

    Run TomTom Home from your start menu or applications folder.

  5. 5

    Reset your TomTom by pressing a straightened paper clip into the reset hole on the bottom of the device behind the release button, then reconnect the device to your computer.

  6. 6

    Click the "Update My Device" button if your computer does not automatically check for updates. Install all updates, then select "Disconnect Device" from the "Device" menu.

Tips and warnings

  • If your TomTom is still faulty, contact TomTom customer support.
  • Reinstalling your device's software will erase the information on your device. Using the reset button on your device will only reset the time.
