TomTom 300 switches off

My Tomtom 300 will just shut off while you are driving it comes back on when the signal is restablished. It happens alot while driving in cities. Anybody with the same issue please help before I throw this thing out and buy a Garmin. It always seems to happen when you are close to your destination it just goes blank and the signal is gone.

Hi there

This happens because files on your card are corrupted after an unsuccessful download.
If you have a card backup at hand, put the card into a computer, format it , and restore backup.
After that the TOMTOM will restart working normally.

If you did not make a copy or backup of the original card, or you cannot reach the computer hosting the last backup.Then follow the procedure below to restore your data :

1. Uninstall the application

2. Reinstall the application

attention_25.gif We highly recommend backing up your device before continuing. questionmark_25.gif
This will preserve any maps and voices you may have purchased.
1. Connect your device to your computer.
2. Go to Computer (Vista), My Computer (XP) or your Desktop (Mac).
3. Double-click the TomTom disk drive to open your TomTom.
4. Make sure that hidden folders and files are shown. To do this:
  • Vista: Go to Organize > Folder and Search Options, click on the View tab and select the option Show hidden files and folders.
  • XP: Tools > Folder Options..., click on the View tab and select the option Show hidden files and folders.
  • Mac: With the exception of some system files, your Mac should already show all hidden files and folders on the TomTom drive.
5. Identify the map folders on the TomTom. These are named for countries or regions such as USA_and_Canada, North_America or any other country or geographical region.
6. Delete all files EXCEPT these map folder(s) and the folder titled ASR, if it exists (the ASR folder will not appear on every device).
7. Properly disconnect the TomTom from the computer and exit TomTom HOME, if it is open.
  • Vista/XP: Right-click the TomTom drive and choose Eject.
  • Mac: Drag the TomTom drive to your Trash.
8. When the TomTom boots you should see a screen with the flashing X.
Proceed to reinstall the application (below):

Tom tom go 300 ''unable to store settings'' ''file access error'

You might have the switch on SD card set to "read only" , This would stop your tomtom being able to write to the SD card ... hence , " unable to store settings " message . .... OR ... the folder where your tomtom wants to store the settings is corrupted ( on your SD card ) so it can't store them.... or similarly , the file is corrupted on the SD card ( maybe the card is damaged ) so the existing file cannot be overwritten . Check out all these possibilities before suspecting any hardware fault on your tomtom ..... GOOD LUCK

I found a toll free number for TomTom, called and actually got a real person. My computer recognized the TomTom (TomTom home was version 7. something); my TomTom unit had software that was too old and it did not recognize the TomTom home. Catherine in tech support sent me a download to update the software and it worked. Thanks for getting back to me. I am attaching the link for anyone that needs to update software in their TomTom GO 300:

If the unit is still under warranty, send it back to Tomtom. Even if the unit is no longer under warranty, complain to Tomtom. There is a problem with the CLA (cigarette lighter adapter). It can cause internal damages to your Tomtom. What happens is that there are three wires in the CLA along with a voltage stepdown circuit board. The wire are +, -, and a signal wire. If the signal wire get disconnect the voltage could spike up to 12vdc. The unit is designed for only 5vdc.

If the unit is out of warranty then try the following website for repairs. They can fix the two chips which usually blows.

"My tom tom wonts switch on. I have reset it and still it comes on with a boom boom noise and shows the 2 hands on the screen. It also shows the loading bar at the bottom, but then it just freezes and nothing happens. can anyone help please ASAP"

Sound as though your Map data card is corrupt. Remove the SD card and check it with your computer using a card reader. Backup the SD card onto your computer. You can run either chkdsk or go to the drive letter under 'My Computer' right click and select properties, then tools, then check now. You can also try starting the Tomtom with the SD card out of the unit. It should show a picture of the Tomtom with a 'X'. You can also try copying the data on the SD card to another SD card.
