For those of you with 02-04 rockford fosgate systems that are looking for a true AUX in, I successfully modded my 6disc fosgate in my 2004 se xterra for an aux input (and ipod charger/line out.) It involves some surgury and about an hour of disassembling and soldering but it's absolutely awesome. Zero hum silence and a toggle switch between audio from CD player and AUX (or universal ipod adapter) I know this is the mod EVERY 02-04 xterra SE owner has been looking for so I'll put together instructions to post into this thread.

I patched the ribbon cable between the intermediate board and the main board (cd player module>intermediate board>main head unit board) I traced and found the pin-outs on the boards and ribbon cables. If you're up for a fairly difficult mod, the kind that requires a steady handed xacto, soldering iron, glue gun and some caffeine.. this is for you. again, give me a couple of days and I'll post the instructions.
