I have an older model, deh-p600. I just received my sirius satelite radio hardware, and I went to install it. I was going to bypass the fm modulator, and go to the cd player directly. Now here's the problem. The cd palyer has an auxilary function. It's listed in the manual, and you can switch to the aux setting in the cd player. I cannot for the life of me figure out where the damed plugs are. Could it be that there really are no plugs, and the aux feature is just a leftover from something?
