U.Z.Z. Satnav
Type GPS
Purpose give directions
First Appearance Rise of the Floaty Heads

The Standard Issue U.Z.Z. Satnav (Satelite navigator) is a device similar to GPS used to give directions, the one Anita used appeared to be lost, as it gave her completely inaccurate directions. It also has sentience, and refused to admit it was lost, though it was fairly obvious.

Despite being "standard issue" Victor had no idea what it was, implying he doesn't own one.
