I'v been trying to find the model number for the P.I.E. aux for the 2003 LS with the THX Navigation. Thanks.

You have to talk to a PIE dealer. Apparently, there were changes in '03 that make finding the correct adapter problematic.

I have an 03 w/ THX Navigation as well. There is a thread where I asked the same question and got a specific model in a reply. That was the model I bought and it worked perfectly. I just forget which model it was.

Ill check it out. The thing is I found the model a couple months ago and now on the website it say it does not work for the 03 with the thx navi and no others on thier site say it work for my car.
