Audio Systems: antenna wire, pontiac montana, antenna line

Question
My brother wants to install a modulator in the antenna line for his ipod.  Some of my recent gm cars and trucks had a plug connector in the antenna wire behind the glove box.  does the 99 pontiac Montana have this connector behind it's glove box?  I thought I would ask before tearing the whole thing apart

Answer
yes but it is by the passanger door very hard to get to it
the best way to plug the ipod in to the pontiac montana is by using the aux button on the radio and the 9 pin plug in the back you also need the correct interface  follow this link to read about them
