Anyone added a second 3.5mm aux port to an existing one?

My Z is great the way it is, but I just picked up a 2010 Toyota Sequoia for the family. It has the OEM JBL stereo system and factory Nav, with USB and 3.5mm aux input ports on the dash (not physically contained within the stereo/nav unit). I am going to have an aftermarket rear DVD system installed and I would like to wire the sound into the factory 3.5mm aux port, but do it behind the dash so it is clean and doesn't leave an external wire exposed. I would also like to retain the factory aux port so that if I want to plug any other device into the system I can. I would like to have remote switch mounted somewhere that lets me toggle between the DVD sound and the dash aux port. So essentially I want to splice into the factory aux input wiring behind the dash and add a second line. I realize I could just do this with a cheap $5 Y-splitter plugged into the existing port and then manually switch the input cable source, but that wouldn't be fitting in a $50k vehicle. Anyone know how to do what I am suggesting and where I could locate the necessary parts?

Well, just a follow-up post to let everyone know that I just had an Alpine rear DVD system installed in my 2010 Sequoia today. The install guy tapped into the aux input cable behind the dash and created a secondary input line hidden behind the dash for the DVD system. He placed a rocker switch hidden in the cubby hole beside the cigarette lighter that switches between the retained factory aux port on the dash and the now-secondary aux input that is the DVD system. Works great, sounds great, and didn't charge me any extra.
