Maxima2008

Need some help here. I was not aware that the 6th gen maxima came with the pop up function in the armrest where you can raise it higher for comfort. I do not know what that feature is called, but it was in the 5th Gen. My Maximas armrest can only slide out longer but it cannot be raised what so ever for comfort. I can open and place things in there naturally, but I was in a friends 06 and NEVER knew this was available for our gen. Do you think I can just purchase an 04-06 armrest and install? Thanks.
