auxilary input

So... my TSX got totaled. I have had these items for less than 6 months since I had the car for only 6 months... yes, I know, sad. Now I've picked up a 3rd gen TL and these aren't compatible... I've got an Aux input so that you can plug your phone/ MP3 player etc. in and play music through...

I just saw a couple of items on ebay for auxilary input. I am looking for interface that will have the option to connect external DVD player so video would work on my navigation screen. Will any of these work? I have 2005 TSX with navigation and CD/AUX button but I don't have factory aux. input...
