I have created two little scripts to "hide" files on your Tomtom.
The purpose is to be safe if you are in country where the use of speed cam files is illegal - like Switzerland.

Unpack the files to the root of your device (or SD card).

In the current configuration it won't work!!
You have to make some changes :
Edit the files move and move2 with a Unix Editor like Notepad++ and change the two lines before the reboot command!!

mv Australia/*.ov2 Blitzer/
mv Australia/*.bmp Blitzer/

That means you change "Australia" to the name of your map folder!
If you don't change it it won't work!
The best option is to copy these two lines and replace the "*" with the name of your poi files.
This way only the cam files will be moved and all other poi's will stay active.
If you only have a few poi's it won't matter but for 100 or so it will take a while to "hide" them.

The names and images for the menu icons can be changed too.
I assume you know how to change a picture...
The text under the icon is changed in the corresponding .cap file:
Again open with a Unix capable Editor and change the last line :

COMMAND|CMD|hallo|move.bmp|Blitzer weg|

"Blitzer weg" is the text under the icon - for the other icon it is "Blitzer Da!"
I hope you will find it useful !

Please check if the folder "blitzer" was created - if not do it manually otherwise it won't work.
If all is correct you will find two new icons in your menu
