Now , with Sygic on the 5800 I`ve downloaded custom mp3 files for the speed cameras warnings ( instead of beeping, I`ve replaced the beep sound of the 30,40,50,60,70 mile warnings with actual voices saying 'thirty,fourty,.....' instead).I then went into the POI settings and manually replaced the beep sound with the mp3s.Can we do the same here?Can anyone check this?
