If I'm not the leader, will other players see when I change the GPS target?

I'm assuming the GPS line I usually follow is set by the leader.

If I change it, will other players see the change or will it only change for me?

For example, Countdown starts and the targets are the Cooling Tower, Administration and the Reactor.

The group leader sets the GPS marker on the Cooling Tower.

If I set my marker to the Administration building would other players see it?

I don't want to do anything that's going to cause confusion.
