Location of Aux input other than front of Radio

[Kokanee]

I installed a Harmon Kardon Drive+Play in my '08 SL last year. I've always wanted to do a hard install however due to interference w/ the reception thru the antenna via the RF transmitter.

I'm wondering is there an aux input in the back of the stereo, or is it just in the front? I'd hate to have to route a 3.5mm audio cable out of my dash and have it plug in the front, just looks half-assed.

Any info is appreciated.
