Everything I've seen has said CCAPs cannot enter the belt. The mechanism in which you gather warp jump coordinates comes from another device (let's call it a nav device since I don't remember the exact name) that you would typically bolt onto a smaller ship and fly to a desired area first, grab the coordinates via some button or functionality on the nav device, then take the nav device back to the CCAP. You can then jump to that coordinate.
So, if you can now use stations as a jump point AND you can do so into the belt, that goes against two different facts I've heard at the same time. Where exactly did you hear that? I imagine it's just hearsay or someone bullshitting.
