GTA: Online. how to use Auto-aim in Freeaim.
Have a friend make an invite only session using auto-aim. have him go to settings/online options and set matchmaking on and have him host a job and thats all.
now wait for the job notice to pop up from your friend and join it. it will ask you if you want to change your targeting mode. select yes.

Then it will say you won't be able to join because you weren't invited. puts you back into the lobby you were in which is freeaim while you have autoaim.

The 2nd time i'ma ruin this ;)
