I have seen many part numbers on this forum but can't seem to find what I need... I am looking for an Aux input adapter so i can add sirius and dvd player audio. I don't care if it disables XM... does anyone know what part number I need? Also, when installed will this new aux channel work off of the XM button or another one? I have a navigation unit. Thanks

 

The blitzsafe hon/aux dmx v2 is supposed to work with the 3rd gen TL.
I don't know if it really does or not, but its supposed to.

You might be able to find it cheaper on some other sites as well.
If you get this working, post some info....
