So I bought my 07 gt used and I didn't realize it at first but the Aux jack doesn't work, when I plug the Aux cord in and press the Aux button on the stock Shaker 500 it reads "No aux audio" I read a ton of forums on how to fix it and also the owners manual on how to set it up to see if it needed to be reset. I had someone else take a quick glance at the wires to see if everything was connected but they said it looked fine. I'm trying to avoid buying a new one just yet, and not exactly sure how to check/ if it would even be a fuse problem... has anyone else had this happen and know how to fix it? I read this happens somewhat frequently to the Shaker 500's.
