packard bell gps 400

[supracapri]

I have got the packard bell gps 400 with destinator nd, and have just put all the speed camera and red light files onto it. I have also added the relevant bmp files for the camera and light icons, and also the "warning, speed camera" wav file.
I have renamed these files to be the same as the corresponding camera files as insructed in a previous article but still my gps 400 gives me the "favourites alert" voice message as well as the the "favourites alert" text on the screen.
How do I make it say "warning, speed camera" and give the relevant icon?

Have I missed something somewhere?

Thanks for any help,

Nick
