Will not turn on. Just says TOMTOM - Tomtom ONE XLS Car GPS Receiver

If it doesn't continue to show the license and owner screen, it means that the TomTom (navigation) software is not running properly. Often it means that the software is corrupt, and it has to be repaired or replaced.

If you are able to connect the TomTom device to a computer (using the USB port), select the TomTom disk, right click and select Properties, and run the TOOLs to check and repair the (TomTom) disk. After completing the repair, disconnect it (from the computer), restart the TomTom - turn it off and turn it back on, and see if you get it going normally. If not, you'll need to restore your navigation software from your backup and see if it works. Or you can download the navigation software from the TomTom website and copy it onto your GPS device.

The TomTom XL 340-S uses the power button as a reset. With the unit turned off, hold down the power button for approximately 15 seconds, until the TomTom turns on. As soon as the unit turns on, release the power button. The unit is now reset.

If you search for "TomTom turns itself on", you will find that there appears to be a problem which TomTom will not acknowledge. Mine always turns itself back on exactly (to the minute) one week after being switched off and runs the battery down. Tomtom have got me to reformat and had it back for repair but the problem remains

the green light shows when i am charging my tomtom but it doesn't turn on.

Try to reset from the back of the tomtom .

Contact TomTom. They were helpful to me.
Suggest u monitor battery and get it charged up. Then reset. See if you can reproduce the problem.
They sent me an email with instructions on how to format the disk or card, then reinstall the software. Then they authorized me a new map download (don't format the disk until they assure you that you can have a new map). Perhaps it's also best to  use TomTom Home software on your computer to backup the files on the TomTom incase something goes wrong.

STEP 1

Connect your TomTom to your computer via USB and open up your Windows Explorer and go to the drive. (It will be listed as TOMTOM (E) or some other drive letter).

Copy the Yellow Folders one by one to your PC. Ideally, save all the folders under a new folder that you name.

You may find that the folder ttntools and gns may not be copied. This is o.k. if they aren't.

STEP 2

Format your Tomtom via MY Computer.

STEP 3

Copy the Yellow Folders from the backup you made in STEP 1 back to the TomTom.

STEP 4

Open TomTom Home
Click on Upate Now.
Install the latest update onto your TomTom.
Once installed, switch your TomTom off, then disconnect if from the PC.

Thats it. From now on, make a full backup using TomTom Home prior to any updates.

Also note, that copying all the files will take some time.
