Aux audio input in Bose premium 2K)
My post earlier was acting up so i will start with the reply here.
The CD changer comes with a cable that plugs into the changer and the other end into the Bose unit. If I rememeber, the plug that goes into the Bose unit is a white rectangular connector that has 2 rows of pins and about 6 to 8 pins in each row. I have done some test to see what signals are present in each. I dont remember all the details but I was able to isolate the Left and Right signal and ground wires. $ total as this changer has separate grounds for each signal (Better quality?). The other wires are control wires that let the changer and the HU communicate. I cant figure out the way it does this, some type of proprietary protocol I imagine. I was able to get AUX sound into the Bose however. This can be done by turning on the unit and playing a CD from the changer. Then you remove the 4 audio wires (Left +, Left -, Right +, Right -) from the connector at the changer and connect your aux outputs to that. It works great but it is not a permanent fix. The bose still thinks the CD is running, which it is, and displays the time, track and disc number but the sound is coming from the source you piggybacked into the harness. I hope this helps but I dont think it is what you are looking for. I am trying to do exactly what you are doing, hook an external source into the Bose unit. I will try to figure it out by connecting into the In-Dash cell phone port on the rear of the Bose. THis would allow for a remote switch to mute (and maybe pause) the current source and allow the external aux audio to be played through the system. Ill update my finding when I have more time. If anyone knows anything about the pinouts on that cell phone connector they would be appreciated.

Man that is going to be tough, I know the bose is always upto using propietary protocals. But the thing is that the 2000+ uses I believe a Clarion Changer. This is the info I got from DaveB, he said the 1995-1999 uses a Sherwood changers.
So that is why I dont think they are using a propietary protocal to do the talking.

Sorry, I know this doesn't help, but I should point out that Sherwood, Panasonic, Alpine etc. could very well have custom built this interfaces to the Bose / Nissan spec so thet it could certainly be aproprietary bus.
