ok so i'm not too sure if this is ven possible but i'm just gonna throw it out there,
so i have 2006 z and when i hold down the unlock button on my remote for a few seconds, the windows automatically go down before even opening the door. my bro's 04 gs430 also does this. i was wondering if this is even possible for tc's. thanks

 

Nope. Nothing I've seen yet for the tC will do this. If anything it would have to be aftermarket... but like I said, I haven't seen anything.

I know the VWs have something similar also - at least you have to put the key in the door and turn it or something.

 

i got the auto down with a python alarm installed at circuit city. Hope it helps. I can hold a button on the remote and it goes down and yeah it is aftermarket
