I swapped the files for the GPS voice from TDU1, and put them into TDU2.
The file structure for this is nearly the same, apart from the sound files itself that have different wording.
Personally, I prefer how the GPS voice sounded in the first game.
*REQUIRES UNPACKED GAME*
- Go to your game directory
- Test Drive Unlimited 2\Euro\Bnk\sound\voices\us
- MAKE A BACKUP OF THE ORIGINAL GPS.bnk
- drag the GPS.bnk from this post into that folder, and done!
I am open to making the file for different languages, feel free to comment.
