We are just about to take delivery of a Sep 2009 Aurion ATX. This is the "older" model without an aux/ mp3 input. The FAQ - see below - refers to a Toyota kit which adds this input. When I rang Toyota about this they said it doesn't exist. I was wondering if someone could help with more specific information, or ideally, a Toyota part number. Q) My factory head unit did not have an auxiliary input for my iPod/MP3 player. Is it possible to add this functionality? A) Absolutely. Toyota sells a kit that enables you to plug your iPod or any other external audio source directly into your factory head unit so you can play your music through there. Alternatively, if you have some electronic knowledge, you can save yourself some money by making this yourself. A member here, 'shane_85', has written a DIY guide and this can be seen in the tread below.
