This is the newest version of the AutoDrive hand control sold by Golden Technologies.  The difference in this #6217B and the more common #6127A is that this control has buttons on the left side to make the headrest move up & down.  Like the #6217A, it has features such as memory buttons and a button to make the chair go into the TV watching position.

This hand control cannot be substituted for a standard two button hand control just because you want these features on your chair; the chair would need the rest of the electronics designed for this control.  Also, you will need to order the same version of the AutoDrive control that you have now; the versions we mention correspond to the rest of the electronics that the chair has, and the versions are not interchangeable.
