Red flashing error indicates corrupt software/firmware. Reconnect tom-tom to computer and bring up software that you installed with device (or take this time to install software). Navigate to "reset to factory defaults" and proceed as the software tells you. After that reapply updates to firmware and/ or maps and disconnect properly from computer. hope this helps

Tried to attach to computer to update since then all I get when turning it on is a flashing red cross and can not soft reset


Since you have said that your TomTom is only displaying a flashing cross (or "X"), it is because the TomTom application is not installed or can not be found. This usually happenes when you attempt to update your unit and it is interrupted (i.e., not properly disconnected from the computer, the TomTom was underpowered by using a USB port on your monitor/keyboard, or lost power during the update. In fact, it might just be pissy.)

Down to how to fix it: You essentially just need to reinstall the application.

1. Soft reset (I know you have already done this but am providing a link just in case: http://uk.support.tomtom.com/cgi-bin/tomtom_uk.cfg/php/enduser/popup_adp.php?&p_faqid=6965)

2. Connect you’re GPS unit to your computer

3. Press the power button for about 5 seconds and the TomTom Home will start.

NOTE: It is highly recommended that you use TomTom HOME to make a backup. You can find out how to do this here: http://uk.support.tomtom.com/cgi-bin/tomtom_uk.cfg/php/enduser/std_adp.php?p_faqid=3171&Lid=1

4. Delete application files (so we can do a clean install), to do this:
- in HOME, click "MANAGE MY NAVIGATION DEVICE"
- Select the ITEMS ON DEVICE tab and tick the box by "APPLICATIONS".
- Then click REMOVE ITEMS FROM DEVICE
- A warning will pop-up, click "OK"
- Select the ITEMS ON COMPUTER tab and tick the box by APPLICATIONS
- Then click REMOVE ITEMS FROM COMPUTER
- Another warning will pop-up, click "OK"

5. Reinstall the TomTom Application by clicking UPDATE MY DEVICE
- Then click UPDATE AND INSTALL
- Once done, click DEVICE > DISCONNECT DEVICE

6. Next, we're going to run the TomTom Clear Flash Tool (the downloads include step-by-step directions for clearing the flash)
- for windows: http://www.tomtom.com/updates/clear_flash/clear_flash.exe
- for mac: http://www.tomtom.com/updates/clear_flash/clear_flash.dmg

7. Safely disconnect.
- on windows: click the SAFELY REMOVE HARDWARE ICON (a icon with a green arrow that is hanging out in the system tray and then choose "USB MASS STORAGE DEVICE" from the pop-up
-on a mac: drag the desktop icon of your device to your trash.

8. Your device should start up automatically. If it hasn't within 10-15 seconds, press the on/off button.

You're done!
If by chance this still doesn’t work, you can try formatting the internal memory or memory card of your TomTom. If you need a link or directions, simply send me a message or reply!

Hope this helps!

TomTom device frozen


If your device freezes at the start-up screen after you turn it on or your device is looping, the TomTom application may not be installed properly.

See some examples of start-up screens here. The image may vary on previous TomTom devices or if you have replaced the image.

Before you begin, make sure you have TomTom HOME installed on your computer (www.tomtom.com/home ).


To solve this, follow the steps below.
Remove the current application

1. Connect your device to your computer using the USB cable or dock.
2. Reset your device.
3. Turn on your device by pressing the power button for 5 seconds.
  • Your device should automatically connect to the computer upon reset. If your TomTom device asks you if you want to connect to your computer, tap YES.

4. Run TomTom HOME.
5. In the Main Menu of HOME click on Remove items from my device.
remove_items_from_my_device_uk.gif 6. Click on the plus symbol homeplus.gif next to Applications. Click in the checkbox on the right to select the application.
7. You will be prompted to confirm the selection, choose Yes.
8. Click on Remove selected items.
2352_08.gif 9. Choose OK.
10. You will be asked to copy the item to your computer before removing, do not copy the item. Instead, choose Back.
The application will then be removed.


Reinstall the TomTom application:
1. Start TomTom HOME.
2a. If you previously updated your device on this computer, click Add Maps, Traffic, Voices etc. and then click Items on my computer.
You can install the application by clicking the plus symbol homeplus.jpg and then Add.

2b. If you never updated your device on this computer, click Update my device.

3. HOME offers to download and install the latest version of the TomTom application.

TomTom 520 won't start


Hi all,
I got the following response to this little problem. Will try it out and hopefully my 520 will work again soon.

To ensure that your device is correctly connected to your PC, please do the following:-

STEP 1 Run the Registry Cleaner Tool

• Disconnect the TomTom and remove any USB devices from your PC, If you use a USB Hub, please disconnect that also.
• Run the RemoveRegEntries tool. You can download it from :-http://tomtom.com/lib/img/cs/S4S/files/RemoveRegEntries_TTGOv1.exe
A Black window will appear briefly then close.
• Make sure that you have got Administrator rights on the PC. Otherwise you may not be allowed to connect new hardware (especially the case when using office computers)
• Reboot your PC

STEP 2 Connect the TomTom

• Make sure the device is fully charged before connecting it to the computer. Ideally a mininum of 4 hours charge.
• Reset the device using a paper clip (see http://www.tomtom.com/6965). When resetting, keep the reset button pushed in for at least 20 seconds, but DO NOT turn the device back on just yet.
• Ensure that your TomTom has power connected to it. There should be a green light on the TomTom unit. If your device came with a Home Charger, please make sure that is plugged in to the TomTom also.
• Connect the TomTom to a USB port on the back of your PC. We strongly suggest that you use a USB 2.0 port and not a USB 1.1 Port. (USB 2.0 ports are faster USB ports, which are standard on all modern PC's, older PC's and some laptops may still use USB 1.1 ports which are slower and can prevent some USB devices from connecting properly).

STEP 3 Switch the TomTom On.

• On your PC, open My Computer
• Now switch the TomTom On while it is connected to the PC with the green light on.
• Look at My Computer, do any disk drives appear as you switch the TomTom On? If so, which drive letter is it?
• Double click on the TomTom disk.
• What files and yellow folders do you see?, please make a note of them and reply back with what files and yellow folders you see. If possible, please provide us with a screenshot showing all the details.

If the device is NOT listed as a 'Removable drive' under 'My Computer' when you switch the TomTom On, try the following:-

STEP 4 Check Device Manager

• Disconnect the TomTom from the computer.
• It is likely that you have a Firewall on your PC, in some cases, Firewalls can prevent USB devices from being recognized by the PC. We suggest configuring your Firewall and security settings to allow all USB devices to connect to your PC. Once you have done this, we suggest trying the steps above again.
• Go to 'Start' and right-click on 'My Computer' and select 'Properties'
• Select the 'Hardware' tab
• Expand 'Disk drives'. If the TomTom device is shown there with a red cross, right-click on it and select 'Enable'
• Check under 'My Computer' to see if the device now shows up as a 'Removable drive'.

We also suggest it is a good idea to try to connect your TomTom to another PC to see if you get the same problem.

TomTom frozen


My TomTom One is acting up. All of a suddent, it has a hard time finding a valid GPS signal. Then, it sometimes becomes frozen at the first screen when you turn it on. When I try to connect to the computer, the menu page comes up on the computer screen, but the unit does not respond to anything. This unit has operated smoothly until now and I have done nothing to change it. Any ideas?
