Cutting into my POI Space?

 

I noticed that there was an audio update(vers. 2.6) for the c330. I'm not going to install it because I don't need Brazilian Portuguese, but it got me thinking.

With the addition of a new language, I would assume that the new audio files will take up more space than the old set. If this is true, does this eat into available POI space?

Or is POI a separate area of internal memory that does not change no matter how much internal system memory is utilized.
