I’m having problems with my Aux input to the Bose system of my 02. I’ve got a PIE adapter connected to the GM CD harness and have connected a MP3 player via the PIE adapter’s rca ports. It’s been working great for quite a while and I use the Aux button to switch to the MP3 player as the input source. This weekend it quit working after I disconnected the battery after a Halltech Trap intake installation. Now when I use the Aux button it switches to the CD display and shows I think CD1 Track 1, or whatever it used to, but I get no sound. After a minute or so it just goes back to AM or FM. The single CD does still work. I read a previous post where it said to disconnect the CD harness, disconnect the battery and then reconnect with no harness, then repeat the process with the harness connected. I have tried several variations on that with no success. Anyone have any ideas what the problem could be? I don’t know where to go from here or why disconnecting the battery would have even caused a problem.
Thanks

I am getting a Delphi Ski-Fi for christmas to put in my 01 and wondered what a Cor-harness is for and the GM 10 Aux box does. I have a CD player but no CD changer.
I remember someone saying to disconnect the Cor-harness from the GM 10 Aux box a few times fixed the problem.
Good luck.
I am hooking my XM Commander up on 12/9 via the Cor-harness and GM 10 Aux...so I'll see if I have any problems too.
Well, tried disconnecting the battery again for over a 1/2 hour a few more times. Disconnected the CD harness one time and didn't plug back in until after the battery had been reconnected. Tried various combinations of disconnecting the PIE adapter from the harness and having the MP3 player attached. I'm at a loss. Can't understand why it would work fine for months and then loosing battery power one time would fu#@ it all up.
Nobody else ever have this problem?
I have seen this problem addressed in other posts. Here's what I found out when I had my XM Commander hooked up today...
The Cor-Harness was hooked up to the GM 10 Aux box. When the installer powered up, the system kept getting the error message.
When he had the system powered up, he then unhooked the Cor-Harness connection to the GM 10 Aux. When he re-plugged it in, the system recognized everything and it worked fine.
I activated XM, and it sounds great through the aux input.
I had not tried FM modulation, so I can't compare...but my sound is excellent.
Help me get my terminology down. The Cor-Harness is the factory harness that normally connectes straight in to the back of the CD changer? The GM 10 Aux is the PIE adapter that has the left & right RCA output cables on it?
If that's the case then I've already tried that. Now I get the little CD icon in the lower left corner of the display, even when I'm on AM or FM. If I disconnect the PIE adapter it disappears after a minute or two. I have noticed that it no longer indicates Track or Cd on the display when I press AUX.
I also noticed that even after disconnecting the battery for over a 1/2 hour the radio still does not loose the AM/FM presets. I would think those would be lost with no power. Am I not leaving it unplugged long enough and so the radio is not resetting everything like it should?
Thanks!

Yes...that seems right. The Cor-Harness comes from the Aux input of the head unit. It goes back to connect to the CD changer. I did not have the CD changer installed, so I bought the Cor-Harness which connected in the passenger footwell to the pre-wired, unused plugs to the right of the fuse box. The Gm 10-Aux is the rectangular box that has the two audio connectors...which then hooks up to the XM commander control box via the two audio cables.
Disconnecting and reconnecting the 10 pin Cor-Harness from the 10pin/CD changer data connector while powered up, allowed the system to recognize the XM as "CD1 Track 1."
If you leave it unplugged for 20 minutes, it should be plenty long enough. Very frustrating...good luck.
Well, not sure what I did but it's working again. I repeatedly connected and disconnected the harness from the Aux adapter with the MP3 player in various states. Connected and on, connected and off, radio on, radio off, differnet modes, etc. Combine that with some expletives and throwing some stuff across the garage seems to have done the trick... Thanks for the help.
