And it does indeed work....just finished installing the Sirius receiver and it's up & running!!!

Congrats! :thumbup:

Fantastic!!!

I was so happy that I had Sirius working that I forgot to check the daisy chain loop to make sure the CD Changer was working properly. This AM I found out that CD's were playing muffled with static so I started taking it all apart it putting it back together in sections and this is what I found out:

CD/OEM Cables to CD Changer Plays OK (stock set-up)
CD/OEM Cables to .977 EXT CABLE to CD Changer Plays OK
CD/OEM Cables to .977 EXT CABLE to CD Changer to Sirius Receiver CD Changer Plays OK
CD/OEM Cables to .977 EXT CABLE to CD Changer to Sirius Receiver to .978 EXT CABLE to CD Changer and it plays muffled with static

Take a look at this post and see if it applies to your situation...

This gets better.....I changed the pin from #2 to #3 per Martin's finding and I get music now ungarbled but when I turn up the volume I can hear the volume knob "clicking" over the speakers.

The clicking could be a missing or bad ground. Check your connections again to be 100% sure.

update....I swapped out the .978 cable for a new one and switched the pin again from #2 to #3 and I still get the clicking sound as I increase the volume with the knob. :mad:
