Why do I have to reset everytime I turn on my TomTom One??

Hallo! Try this: press reset +poiwer on for 20 secs, release reset but keep pressing power 20 secs, it should power the light on, very fast to connect to computer in this time, because it stais on 10 secs, open it like a map, backup ALL data in a new map, format the device, connect to TomTom Home, make the upgrades, copy the maps Maps and Voices back to your GPS.

Your TomTom may have to be reset. According to the manual:

To reset your ONE XL, use a straightened paper clip, or something similar, to
push the reset button. The reset button is next to the memory card slot on the
bottom of your ONE XL. Then turn your ONE XL on.

Remember, after a reset, your TomTom MAY take up to 20 seconds to start when using it for the first time.

Hope this helps.

hi try a soft reset, first make sure your battery is full. if you use a sd card, remove it. push reset button on bottomside of your tomtom, its in the middle next to "reset" push it with a small pin, paperclip or something, for at least 15 seconds. after that push on/off button for minimum 5 seconds. if used push back sd card. good luck

If your TomTom GO/ONE/RIDER is frozen, won’t turn on or does not behave as it should, it can be fixed by resetting or restarting your TomTom device.
A reset will not delete any data from your device, with the exception of SMS messages on TomTom GO500/700.

1. Connect your GO/ONE/RIDER to the power charger. If you have a power charger, use it to power your TomTom GO/ONE/RIDER. If you do not have a power charger, make sure that the battery in your TomTom GO/ONE is fully charged.
   Note: You need to charge your GO/ONE for at least 2 hours using the 12-24V cigarette lighter adapter.
2. Reset your GO/ONE/RIDER. To reset the unit, you simply have to push a straightened paper clip (or something similar) into the RESET hole on the device.
   • On TomTom GO 910/710/510, the RESET hole is located on the bottom of the device.
     
   • On TomTom GO 700/500/300, the RESET hole is located on the bottom of the device with the word RESET right next to it.
     
   • On TomTom ONE, the RESET hole is located on the bottom of the device, with the word RESET right next to it (just below the SD card slot).
     
   On TomTom RIDER, the RESET hole is on the bottom of the device, behind the SD card door. When opening the SD card door you will see the RESET hole on the left, right underneath the SD card slot.
   
3. Your TomTom GO/ONE/RIDER is now reset. Finally, press and hold the power button for 2 seconds.

push the reset button for 15 second then push on/off button for 5 second, it will start now

DONT error check with windows this can cause errors itself !

HARD RESET

Tends to fix quite a few problems and is specific to TOMTOM's that have the tiny reset hole on the bottom of the GPS

Commonly known as a "hard reset"

You need a paper-clip or something similar ( Avoid needles )

Paper clip in the tiny hole by the card slot.

Push it in firmly whilst the unit is powered up (not too hard) for about 3 seconds then release

You may have to power down and then up again and even hold down the power button a little longer the first time you do this

You may also have to do this without an SD card in.

If you have a card in then the windows error checking may give you some issues.

You may have to re-format the card (FAT-32)

And copy your tomtom files back to it from the tomtom itself..

Which model is it ?
On the Go 300/500 series there's a reset in the base. You will need a thin pin or similar to reset.
Take out the map card then turn the unit on.Push the pin into the reset hole at the base.
You will then get the start screen and the maps will reload once you replace the memory card.
On the 7 series, simply hold the on button down for approx 15 seconds until the start screen begins to show.

You have the option of unchecking items you don't want installed and updated every time you connect to TomTom Home. Reset the entire unit and update again to fix the error

I had same problem. I called 866-4TOMTOM and was told that they would send a replacement. They were quite courteous. Be prepared to provide serial number that is on bottom of device.

This worked, it took about 2 mins. and no more white screen.

Software problem I sure.
