Tomtom 720 Help Needed


Standard Member
Have just bourght a new 720. However, when I switch it on it seems to boot up, but then a red flashing x appears.... Any advice on what I can do to get it running (I've already reset it a couple of times...)?

Yes, I charged it up for a couple of hours, then disconnected the device as advised. However, when I turned it back on, it starts to boot up then the flashing cross appears??


Was that when it was on the charging dock? Try ttaking it off and power it down then back up again, if that doesnt work try resetting it.

there is a firmware fault which occasionally occurs and it can be quite a lengthy procedure to restore - other people on these forums have had the same problem and my advice would be to take it back to the shop and get a new one. That is the simplest thing to do. If you cant do that then i would hunt for the link to a guide on how to fix it in these forms. If you cant find it then just post that you cant and i will have a hunt when i get some free time.

Thanks guys, I finally got a reply from Tomtom which seems to have fixed things... For those with similar issues I have included the solution below:

In this email you will find the solution for the error on your TomTom. This solution can be used in the following situations:

• The device hangs in the start screen (splash screen)
• An SD-card with a red cross is displayed on the screen
• A picture with a red dot and white cross is displayed
• The device can’t be turned off

If you haven't already done so, please download and Install TomTom Home from

If you don’t have a full backup of your TomTom yet we advise you to make one before continuing with the steps in this email. You can make a backup by following the steps below:

1. Reset your TomTom device: and connect it to your computer.
2. Click on 'Backup and Restore -> Backup' in TomTom Home 2.0
3. Enter a name for the backup and click [OK]
• IMPORTANT: When the software is asking to delete parts from the backup click [NO]

After the backup is made you delete the files from the root directory of the TomTom. Follow the steps below to do this:

1. Reset your TomTom device: and connect it to your computer.
2. Open My Computer in Windows, or Finder in Macintosh from your desktop and turn on your TomTom device.
3. On your screen a new removable disk appears, this is your TomTom device, click on the disk to open it.
4. You will see a list of folders and a list of loose files
5. Delete all of the loose files. IMPORTANT: The folders with their content must NOT be deleted.
5. Close the window when all files are deleted by clicking on the [x].

Next we will reinstall the application via TomTom HOME.

1. Start TomTom HOME on your computer
• TomTom Home should automatically check for updates and prompt you to install them, if not:-
2. Click on 'Update my device'. If you get the message 'No Items Available', or there is not an application to download, click on 'Add Maps, Traffic, Voices etc -> Items on my computer', select the application and click on 'Add'.
3. Select the Application update.
4. Click on 'Device -> Disconnect Device', then turn off your device when it is done installing and disconnect it from your computer.
5. On a PC, in the System Tray by the computer clock, click on the 'Safely Remove Hardware' icon and disconnect the TomTom also in this way.

When switching on the device it should boot as normal again.

I had exactly the same with mine after updating and just took it back to the shop for an exchange


I have TomTom 720 & there seems to be some glitch.

Sometimes it directs to different directions & also I CANT figure out how to change the clock on the gps.
