Milton, thanks for reply and the photos. I like it. A lot. I have an 02 Camaro SS (another wheeled passion, along with 3 SVT Foci), and it has the FM transmitter for iPod connectivity, installed by prior owner. Works great, but not sure if Audiovox unit--I will check. Until I saw your post and photos, I didn't fully understand the wiring. Now I do.
And your comment about signaling the iPod to go pause, when ignition is turned off, is important. Thanks.
