No, it won't. I actually developed this product so that I could stop having to use AUX in my own car. Even if I did add this feature, you'd have to wire it from the trunk to where you'd want the AUX input to be :/.
Thanks for your informative reply here and the very friendly, helpful email you sent me earlier. I think I'm going to go for this! Am I right in assuming I can always revert to AUX-in by selecting it instead of the "CD changer"?
