Hello, first of all, I have spent hours reading through the various aux threads to see if someone had a solution to my problem and could not find any. All of the problems people normally have with the aux is that there radio is not compatible with the aux feature in the first place. Here is a little back round information on my car. I have a 2005 330CI vert. I have the CD53 Alpine radio with the mode button and my radio p/n is 65-12-6 943-429. The head unit was manufactured in may 2005 so my radio for sure has the aux capabilities. I have the oem BMW iPod interface hooked up to my car as well. I ordered a BMW aux cable from my BMW dealer and installed it today. I followed the instructions exactly, hooked the cable up to the back of my head unit, there is only one hole the cable will fit in so its really a no brainer. I turned on the car to test it, hit the aux button and scrolled through the modes a few times but no aux showed up. I then plugged in my iPod to the aux cable because I thought maybe there had to be a device connected for it to recognize the aux, that did not work either. I tried un-plugging and replugging cables with no success, I fiddled around with it for about two hours as well. I consider my self a decent diy guy, but for the life of me I can not figure out this aux thing. Is it possible I have a bad cable? lol
All of your guys help is greatly appreciated. I have included some pictures as well to aid in you guys helping me. The first picture is the head unit information and the second one is the aux cable hooked in to the head unit cable mount that you stick into the back of the head unit (aux cable is the gray one on the left).
Thanks, Jacob



This is the head unit info



The gray one on the left is the aux cable that goes into the back of the head unit. The black cable on the right has something to do with the sound from the iPod interface. I am not sure what the other black cable dangling down does, if someone knows this and would like to tell me that would be great!

Thanks again for your guys help

I can't help with your problem... but the additional black connector that you pointed out is for the CD Changer.

Have you tried disconnecting the iPod input and using only the Aux?

Good luck with finding a solution!

I have a 05 with Nav and my dealer told me it is not possible to have both a OEM iPod interface and aux plug. Bummed me out but I found some aftermarket solutions that allow this.

I will try this tonight, just using the aux and disconnecting the iPod interface. Thanks for the good advice. I will post an update after.

It shouldn't. The OEM iPod solution is junk. AUX + decent aftermarket solution via CD changer input is a better solution.

Dang, I don't have navigation but as I mentioned I do have the iPod interface from BMW. This could be why it's not working... Like I said in the post above, I will disconnect the iPod hook up, try the aux then, and report back with the results. Thanks for this information you got from the dealer. This would really suck if we could not use both aux and iPod interface. Just wondering, what was the after market solution you found?

I agree! The car came with the OEM set up.... But I still should be able to use the aux correct?

no. they use the same channel. Thats why the dealer said it wasnt supported...
Ok, I understand. But since the iPod interface takes the place of the cd changer, I heard the aux still works with the cd changer. So wouldn't the aux still work with the iPod interface?

I was told it wouldnt. Just passing the info along. He gave me some kind of technical information but I forgot it all already. haha. If you unplug your ipod interface and try the AUX and it suddenly works, then we will have our answer.

Why would you want the ipod adapter AND aux? Doesn't make any sense to me.

What makes even less sense is having anything Apple in the first place. LOL sorry that conversation is for another time :)
I like to keep an ipod in the trunk with all music and controls on the nav/steering wheel. Sometimes, though, I want to listen to streaming music, and that is where the AUX/iphone combo comes in handy.

aftermarket iPod interfaces take place of the CD changer

OEM iPod interface takes place of AUX

I am going the Alpine KCA-420i/Intravee solution, but I am not sure how good it will be for cars without a Nav screen (and they do not sell the Alpine adapter anymore....ebay?).

The OEM BMW ipod interface does not connect through the CD changer hook up, there for it takes the place of the aux cable. So the conclusion is for e46 cars, you can not have the oem aux with the oem iPod interface as stated above by other users.
Thanks for your help you guys
