Stereo & Electronics - Aux button on Camaro Monsoon

I have a "Ipod2Car" adapter on my camaro for about a year and it worked fine, but now it's no longer recognized when I press the CD/Aux button. Everything appears to still be hooked.

Any ideas what would cause this?

Thanks.

Sometimes adapters like this need to be reset by unplugging them from the head unit and reconnecting.

Thanks for the suggestion. I'll give that a shot.
