You could try reseting the device

1) Turn the device off.

2) Press the Reset button located on the bottom of the device (you'll need a paperclip to do this).

3) Turn it back on. See if it works now.

Or...

1) Do you have Tom Tom Home set up on your computer?

2) Did you ever make a backup?

If so, now is the time to restore from backup.

To restore factory settings:

1) Turn on Show All Menu Items in the Preferences menu.

2) Tap the Reset Factory Settings button (it's on the last screen of the Preferences menu).

Best of luck to you.

Did you install and use TomTom Home program on your PC? Did you backup you 520? If you did you can restore the contents. If not you can reinstall the Navigator Application from TomTom by using update in the TTHome program. Unfortunately It will not give you a map, you will have to ask TomTom if they will help you or if not buy a new copy. If the unit is fairly new you are entitled to an update but that may have passed. If you want to spend some time it is possible to download a pirate copy but it needs to be cracked and files updated. A good site is the IPMART forum

Tomtom uses the generic usb drivers. You can download tomtom home from the download section of the tomtom website

Go to this site for your map problem. http://www.gpsunderground.com/forums/forumdisplay.php?f=38

Tap "Reset factory settings" button to restore the factory settings to your TomTom XL. All your settings, including Favourites, your Home location, warnings for POIs and any Itineraries you have created are deleted.

Your set needs to be opened, and have the following checked, regulation semi conductors of the power supply. or resistors changing values at the supply, or capacitors not filtering ripples. thanks

Hi canal_boat_m

Try this solution:

STEP 1 Un-install Tom Tom Home from your PC

STEP 2 Click on the link below:

http://tomtom.com/lib/img/cs/S4S/files/RemoveRegEntries_TTGOv1.exe
This will download a little removal program for the Tom Tom Home program.
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 3 Visit Tom Tom website and download the current new version of Tom Tom Home and install it to your PC
STEP 4 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.
Your Tom Tom should ask you to 'Connect to Computer' if it does tap YES.

SOLUTION:
Your unit should now be recognized by your PC.

IF IT DOESN'T then follow the instructions below:

1. Connect your unit to your PC;
2. Copy two folders to your PC (namely 'Raster' and the one which holds all your maps - probably called 'United Kingdom and Eire';
3. Using Windows Utility, right click on the Tom Tom drive unit and select Fomat;
4. Switch off the unit and soft-reset it with a paper clip (but hold it in for at least 20 mins) and then re-connect it and power it up;
5. Tom Tom Home should now detect the unit and your unit should ask you to 'Connect to Computer' so tap YES;
6. Tom Tom Home will now say your device needs updating - and if you apply all the changes it will restore it to Factory Finished!
7. Then all's needed is to replace the two folders you backed up and any other items like mp3's and sounds, pics, etc.

I had the same problem until my wife quickly figured it out.Touch the main part of the screen and then touch change preferences.Hit the forward arrow several times {4 on mine}then you will see "set clock".I'm not sure if i have a 520 ,but it is a tom-tom.

my tom tom 510 would start, i have charge the tomtom with green light on, but tomtom is not coming up
