Basic instructions: Remove the guts, cut two pieces of aluminum channel to fit into the opening where the dial originally was. The channel pieces are glued in to hold the iPod in the location where the dial was. The iPod slides in and out of the channel, so it is held securely, but not permanently.
Fasten a short extension cord inside the back of the radio shell (glue it, wire tie it, or use a screw to hold it in location). The extension cord is to plug in the iPod charger and a small iPod speaker of choice - either wired or bluetoooth. Paint the shell before attaching the extension cord whatever color you like and attach small "knobs" to the front for appearance. I used axle nuts painted metallic blue... done.
