I have my sons gn installed with the latch. My manual says to remove the head rest. I followed the directions and even had. My fiance try. The head rest will not remove! I pushed the button in and pulled up...and it will adjust up and back down bit will not remove. Am I doing something wrong? Is it ok to leave it on? I tried the other side of the car and that one won't remove either. The seat fits wells and is tightened well so I believe its safe..but the manual says to remove..and I can't!
