Tom Tom Manager said there was an update available for my Tom Tom One. I connected my Tom Tom to my laptop and used Tom Tom Manager to began the download. My laptop "froze up" during the update (>2 hours) - now the Tom Tom won't recognize the computer nor will it boot when disconnected. It just shows a Tom Tom screen with a red "X" on right side of screen.
Remove the SD card
The card needs to be formatted properly first that's all,
formatting is better done in a card reader.
Right click on it and select format select FAT32 as the files system
Update your device without the SD card.
Make sure your GPS runs OK without the SD card
Now re-connect the tomtom but don't let tomtom home run. exit TTH if need be.
You now ned to select your tom tom which will also show as a drive.
In windows explorer select tools then folder options.
Click view and tick the box for "show hidden files and folders"
It may warn you but you can ignore it.
then just copy ALL the files from the tom tom to your sd card
DO NOT USE CUT AND PASTE !
Once all the files are on switch off the tom tom and insert the sd card and re-boot
It should now work again
