Went to radio shack to get a cable, the one I got says 1/8" stereo plug to 1/8" stereo plug. It fits in the roady 2 but not the AUX input which seem a bit to small. What do I need?

 

That's what my AUX uses

 

Me too

 

So it was dark when I picked it up and wasn't looking at the right section I told them to install it under the toggle switches and they installed it into the empty toggle switch where Im going to have my Rear fog lights added! Someones getting a nasty call tomorrow!
