Hi! On the shaker 500 pictures I saw the AUX button and that's is great. However, where is the actual AUX unput located? Is it in the trunk?

That would be fairly inconvenient. I am planning to connect satellite radio (XM) via AUX input. This is how I currently have it setup in my Camry : Delphi portable -> Radio Shack ground loop isolator -> Aiwa radio AUX input.

Ground loop isolator is needed to eliminate hamming noise. "Simply put, "ground loop" is a condition where all your electrical "grounds" aren't at the same electrical potential, namely zero volts AC and DC." (from http://smr-home-theatre.org/Ground-Loops/).
Thanks for answering!

 

And I contacted a Ford dealer in Pleasentville last weekend and he didnt know poo...
