diffrent voice prompts? and no speed warning?

i heared you can use diffrent voice prompts..kinda like tomtom's mr. t and john cleese. is that true?
if so where can i get these sounds?

also can you turn off the speed warning?
if so how do i do that?

MapThis reads MP3 files, so you can simply replace those in system/sounds/, or you can record your own :).

In the config file, just increase the value for the speed warning to 1000 or so.

is there a way to rip the tomtom sounds to mp3s?
they are in a .cfg file or something like that/

You can download them off the web somewhere.

yea but they arent in mp3 format
