I read this write-up, and it makes sense.

however, in my ONE LE, after selecting a default (ie, from the factory, not custom) POI to warn, the next screen allows us to choose a alert (ring, bell, buzz) that will play when you are a certain distance from the POI. I'm assuming custom POIs (redlight cameras, speed traps) are the same way. So if TomTom allows usto choose one of their alerts, dose that mean there's no need for *.ogg or *.mp3 files?
