Picked up a second oem alpine mbus changer, same year same changer inside and out, except for labels (CHM-S601 should be compatible) but this one does something similar. The motor spins and attempts to pull a disc out of the tray regardless if there is a magazine or not. I am beginning to think the head unit itself is sending some bad junk down the mbus line. Is there anyway to force a reset of the audio system outside of a battery pull?

It sounds like your changer is on the way out. I'm not sure pulling the head unit will do anything to help but I suppose it might. You could just try unplugging the CD changer and see if that somehow forces a reset. The DIN cable on the bottom of the changer comes directly from the HU and supplies both power and commands to changer. That will at least save you from disconnecting the battery.

With the radio bezel removed, I stripped the paint above the radio speed-volume control switch. Removing the paint from the bezel was easy. Six hours soaking under Easy-Off oven cleaner removes the paint without damaging the plastic. Very simple.

I then installed a 3.5mm stereo mini-jack, available from any Radio Shack or your local electronics parts supply. I first soldered a set of RCA cables to the mini-jack and insulated the solder joints using JB-Weld. I wanted to make sure that no tension on the cable would weaken the solder joint.

The 3.5mm jack is threaded so the size of the hole you drill in the plastic bezel is important; you don't want to make it too large a diameter. I used a step-drill bit to get the hole to just the right size so that the jack cut it's own threads as I screwed it into the plastic from the back side of the bezel.

Before popping the bezel back in place, all I had to do was plug the left and right jacks of the RCA cable into the Interface module.

To use any external player, you just connect the player to the 3.5mm jack using a stereo cable, either via the head phone jack or a line-out jack. You then use the "Mode" button on your stereo to select the Aux-In interface which registers on the radio display as CD 1, Track 1. Volume is controlled through the stock stereo system (including your steering wheel controls), though you may need to adjust the volume output of your player to get the output levels set correctly. You then use your external player to select the track of your choice.

I can now use any portable audio source, including MP3 players, portable DVD players, laptops, anything with a headphone jack. The audio is pristine, sounding just as good as any CD player and you do not need to worry about the limitations and problems associated with an FM modulator or one of those hokey cassette adapters.

Without going through the expense and headache of a full head-unit replacement upgrade, I think this is the most cost-effective option for taking advantage of today's audio technology without compromising the integrity and appearance of your stock stereo system. Hope this helps!
