Help! TomTom One 130

[fvs]

I'm trying to customize the start up and shut down screen on my TomTom ONE 130 (using a MacBook). I replaced both "splash.bmp" and "antitheft.bmp" files with my own bmp files but now I have neither start up nor shut down screens!

Can anybody help?

Thanks, in advance!

Edited to add: When I go into my TomTom via the computer, or via TomTom Home, I can see both files there.

use the generator to make them.

Don't have the images as a .bmp file though as it will convert it for you to that format.
