After they/we changed to ICS they had this nice pretty navi-girl's voice.
While it was working a few weeks ago we were out of town (in a rental car from the ariport)... the voice will suddenly change to another person's voice (like an older woman's voice and slower). After a minute or two, it will then change back to the new/younger navi-girl's voice. It's like she went out on a bathroom or smoke break!!! That was a good laugh each hour or half hour when the voice changed to the other person.
Then they totallly crashed it with the maps/navi update last week :\
