Harmon Kardon Drive+Play for 2005 Prius

Hey guys, I'm wanting to install a Harmon Kardon Drive and Play in my 2005 Prius (no center console aux input).

I've been reading and saw a couple people inquiring whether the 2005 Prius stock radio has a cd changer input, and if so, whether it can be used to hard wire the Drive and Play, but I can't find an answer. Can anyone confirm if this is an option? If not, does anyone have any other ideas? I'd prefer to NOT use the FM transmitter, nor would I like to change stereos.

I've had this Drive and Play sitting in the box for several months now and I'd like to put it to use Any help would be appreciated. Thanks in advance.

 

No ideas, guys? I'd really like to not go the FM transmitter route but that seems the only way I know of unless someone else has any ideas.
