First of all, it's been a while since I revisited the Maxima Forum. The last time was when it was run off of someones computer at the university of Ohio. Anyway, I am going to be installing a computer, as well as some other goodies, in my 2k Max this summer. I am going to use it for GPS, MP3s, DVDs and what not. I was wondering if anyone has any info on how to connect an auxillary input into the stock premium Bose Deck. I have the 6 disc mounted in the trunk which leaves that one connector on the back open. I believe this is for the in-dash cell phone which has the capability to mute the sound on the current source (CD/CHNGER/TAPE/FM/AM) and play the sound from the actual in-dash phone through the bose HU. ANy info would be great before I start playing with the wires.

Hey Dan- I am attempting to install an XM receiver in my 2002 Bose unit. What type of signal input does the Nissan CD changer plug into in the back? I would like to wire the XM receiver into the Bose unit line level as an aux source.

 

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.

 

I just spoke with my local dealer. Apparently, the DIN plug from the CD changer to the HU carries left, right and control. While the white Molex connector carries power, ground and remote turn on. Now it seems that I could take a DIN connector and pin L+, L-, R+ and R- to it. The rub comes in that when I try to select the "Aux" source, I don't think the HU will recognize that there is a device present. Any thoughts?

 

I hear what you are saying. I am not sure how you can convince the Bose HU that there is a changer(or whatever) present. I dont think its something as simple as the HU sending 12v to the changer and the changer sends it back. That way if the 12v never came back to the HU then it would know that there is no device present. Thats why the audio wouldnt get played. If you have to actually communicate with the HU via the data lines then its going to be more difficult. Like I said, Ill have more time to play with it over xmas break. Ill try and look for the answer and let you know

 

Great thanks!
