Kenwood Switching

Im using a Kenwood DVD in dash with a kenwood changer control module to switch between an Ipod interface and a Sirrius Radio, both plug in through the changer port but since the unit only has one port the customer was sol this box as a source selecting unit. On this unit there is a switch for aux on/off and protocol O/I. I need to know where to set these switches. Basiclly right now I can get the Ipod to work but no sirrius. Now the crazy part is it doesnt matter if I set the souce sellector to 1 or 2 I get Ipod either way. Either I have these switches set incorrectly or the box is screwed. Unfortunatly I dont have the model number of the equipment or the current placement of the switches. Im gonna go on a limb and guess that Kenwood has only ever made one multi changer source selector before and Im also guessing they only have one Ipod interface and one true sirrius add on so That shouldnt be a big deal. If anyone knows where I need these switches set that would be great as the customer is getting kinda antsy that his 4000 video system wont play sirius right now.
