This mod will replace the old female GPS voice with Microsoft Anna, the girl that speaks when your using Windows Vista/7.
Forgot to say, I didn't change the BING_BONG voice. However, you can modify that yourself if you don't like it.

How to install:

1) Go to SparkIV
2) Find gps.rpf in Rockstar Games/Grand Theft Auto IV/pc/audio/sfx
3) Open gps.rpf and find DEFAULT.ivaud
4) Replace DEFAULT.ivaud with the one in the download.
5) Find an advanced car with a female GPS voice and ENJOY!

Note: I've added the backup inside so you don't have to worry about the original file!
