Supposedly you only get one if you did not get the Navi.
I complained I didn't get the ipod holder so the dealer ordered me one. Later, he told me you are only supposed to get the ipod holder if you did not get the Nav system (i have the Nav) but since he agreed to already get me one, he would.I received one, I have NAV. They handed it to me in a big zippy bag with other accessories and manual. They also gave me a cheezy leather pouch for the key fob and a nice looking Lexus keychain.
You should ask for your leather pouch as well, that was included. Mine was actually in the glove box, the sales man took it out and gave it to us. If it wasn't there, someone possibly snagged it but you should ask for it. As for the keychain, maybe it differs from dealer to dealer, the keychain we received has the Lexus logo in the front and the dealer and road side assistance number on the back.
