theres a thread on SL and it made me finally take pics of the button i used for my push start. figured id post em here too. and you can post yours too, if you have push start on your xD.
yes, still needs a key, works the same way an S2000 does.
the button is from a camry, i think, also, my cruise control has been relocated since i have a different steering wheel. and i painted my cluster trim black.
