Audio Systems: Adding Aux Input to 2006 Montana with existing RSE, pontiac montana aux, montana audio input

Question
2006 Montana with factory stereo.  The existing Aux input (12 pins I believe) at the rear of the unit is taken up by the the DVD system for the back seat.  Can I add a second aux input?  The aux input add ons I have seen all seem to require the availability of the existing input at the rear of the deck.  Thanks in advance!

Answer
THIS INTERFACE will plug into the 12 pin plug on the back of the montana radio and will allow you to keep the factory video system and factory xm radio
you don't lose any functions,
good luck
