I couldn't go to third person to see because the server was FPP only, but when viewing my inventory, the GPS which was equipped on my Leather backpack had it's model not only on the backpacks strap, but also it was placed on the top rear of the backpack itself. I don't really know why it's doing this since only have one GPS equipped in my whole inventory, there is nothing equipped on my field vest because there isn't a radio slot for that vest, so it must be a wrong placement or something.
