What is the best current I-pod interface with an Aux input?

I've been using a USA Spec PA15-HON2 with my last two Accords. Unfortunately it is not compatible with the RL. I called USA Spec and they make a model for the RL, PA15-ACUxl. According to the manual it plugs into the XM receiver in the trunk. Then I will have to run the Ipod and Aux cables to the center arm rest. That doesn't sould like much fun.

Are there any other units I should consider?
