Our first favorite:
POW-MIA Highway has 2 other names here... Nobody calls it POW-MIA Highway.. except the Garmin!
She calls it powmia highway (sound it out instead of using the initials)
I wonder if you're in my area?
The GPS unit would really be confused if they called it the 'Road to Nowhere' (that's the local's name for the road here - it does sort of go somewhere now)
