Tom Tom 520 Reset

I think maybe it needs to be reset mate, but take the sd card out before you reset it, press and hold the reset button for about 15 seconds and then turn it back on and then load the sd card and the maps should reload

Try pressing the reset button under the base of the TT. Then plug it in to the PC and you should beable to clear the memory from the on screen application.

go to there web site they are great on helping out.

You don't say which operating system (navcore) you have installed on your device but there were some bugs in some of the navcores tt released.
Try this:
Make a complete backup of your device on your pc. This is very important. DO NOT SKIP THIS STEP. Make a new folder on your desktop open the drive of your tt and copy and paste everything on the tt to the new folder. This will take awhile. DO NOT USE TT HOME FOR YOUR BACKUP!!!!
Then reformat the drive on your tt device. Turn off your tt while connected. Then turn your tt back on and let tt home reinstall the navcore. You may have to do this several times to get the latest navcore back onto your device. After you have done this copy and paste your maps and bmp images back to the root of your device (copy and paste these items to the drive letter of your device. DO NOT OPEN THE DRIVE).
You should be ready to go.
Hope this helps

If you have a memory card in then remove it press the reset and try to start up again.

This problem is usually the way the memory card is formatted.
I solved mine by doing a search for "format tom tom memory card" or "format tom tom SD card"

After I had done that I backed up my TT then put the card in and then restored to the card and all good from there on.

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.

Do a soft reset by holding the power button down for 15 seconds. then power on and off. it should work. It did for me. if not, call tomtom. they are willing to help quickly

To reset your tt 520 use a straightened paperclip and insert it into the reset hole on the bottom of your tt 520 for 20 seconds.
Hope this helps

Perform a hard reset. That should delete every last bit of info you have saved on your tomtom. To do this press and hold the power and reset buttons for about 5 seconds.

Sai.
