What is the Tanger GR bus terminal destination?

I would like to check buses from Tanger to Tetouan but I have one problem. I can't figure out whether it is Tanger MED or Tanger. The page I've found it is in French.

Here is the page: http://www.ctm.ma/horaires-et-tarifs/acheter-un-billet

You can find there departure destination either Tanger or Tanger GR so I suppose that Tanger GR should be Tanger MED but I have to be sure.

Could you give me an advice?
