Can anybody help me?

first check your bootloader
Checking bootloader (the only reliable method)
Enter a device reset 15 sec.
Then turn on the device and hold the start button until you
get info screen. Which bootloader is there.
---
Update (if your current bootloader version is lower)
This first to version 5.5022 .
!! BE SURE THAT THE BATTERY IS FOR MORE THEN 50% CHARCHED !!
[Please Register or Login to download file]
Put the bootloader on a SD card 2GB or less. Read the txt file wich included in the
bootloader.
If your current boot loader, is version 1.xxxx stop first !! and report it here on the forum.

1) Take empty SD card from at least 4GB SDHC class 4 or higher.
2) Format the SD card Fat32 once slowly. If it's a new card then you can skip this.
3) Use NavCore 9.510 and unpack it (winrar o.i.d) and place the files and folders on the SD card.
Insert SD Card in the device.

4) Reset the device (at least 15 sec) and then run it till the notice "No Map found"
5) Use your choosen map. Unpack it and
Copy the new map to your SD card in its own folder.
When you open the map you see the individual files.
Not a map in a map.
6) Copy "FastActivate.exe" to your TomTom device root (internal or SD Card).
noref.php?url=http://linkcrypt.ws/dir/m24dq269u7183k4
Run "FastActivate.exe".
Select 2
Done
7) SD card in the device. Reset the device (at least 15 sec)
Start the One and hopefully it works.

Did what you wrote and it works with a 2 gb card.

Thanks for your help

It works with a 16 GB micro sd card.

Is there another link to the bootloader?
I Have a One XL with bootloader 5.3026 and navcore 8.010 I would like to upgrade to navcore 9.540 I guess I need to update the bootloader before installing the navcore?

Cheers!

You don't have to update the bootloader but you'll get faster transfer speeds/can use bigger SD cards if you do

The link to it has been fixed in post #2 above
