update, Ive done this same procedure to my buddies e60, and his sounds great, all bass, volume is there. all procedures remain unvaried and my cable has absolute continuity with zero ohms resistance all the way through the end of my auxiliary cord which hooks to S3 phone for mp3. The difference between his Logic7 system and mine is that I have an MY06 and his is MY04.. Untill now, I did not know there was a difference, but his had the X13813, while mine did not. Now I am finding out there is absolutely no different pin combinations (even though a few different ones produced sound, but with no different results) and I am coming to the conclusion that I may have a blown fuse that would still allow the radio and cds to operate normally but to limit aux? Or the freakin model year L7 isn't compatible? Chime in guys.

 

Hi, i would like to get some insight as to why i do not have any of the X13813 X13812 block?
My car is a 2004 545i with logic 7 and no cd changer. I bought an aux retrofic from a seller on this forum that fabricate these aux cable and sell them on ebay not the dealer aux.

X13813

I think i found the connector on realoem but i am not sure which one it is. Would it be connector number 8 or 11?

Bro, Everyone who has a headunit in their car has the X13812 block already. It is the harness that plugs into the back of your MASK/CCC and sends signals to your speakers (Background in your pic). The only thing you MAY possibly be missing is the X13813 like in my situation. This I cannot explain, but almost seems like they went a different route to enable the cd changer in my car.
Looks like 8 would be a good shot, but Note, it says Ended. Don't know if they sell those suckers anymore. I got one off an old computer. Used a connector running off the power supply to the mother board, and it fits after some trimming.

 

Thanks buddy. You're right, i am missing X13813 and i will figure something out or find one off a wrecker.

 

No E60 is exactly the same. First, one is an 04 and the other is an 06. Second, one may have different audio setup. I do know that there is a difference in L7 vs. High-Fi audio. I don't think you blew a fuse. But you can always check them. I think that you need to double check your connections and your setup. There is info here that pertains to this. I have seen it a long time ago. look for brenden ernst's posts I think he found out the hard way when he went to manufacture his own cables and they didn't work for a few people because of this. It was the instructions that were off.

As far as the coding, you need to change nothing except the FA (vehicle order). You do this by manipulating both main storage modules for E60 which are CAS and LM. After this you need to process the entire vehicle. It will grab the FA and notice the any changes. It will specifically pick whatever modules it knows are missing info from the FA and then will change those. That's it. Otherwise, you may lose these if the vehicle is every updated. It needs to be hard-coded in the FA.

 

thanks achtunge60, I will definitely get a new cable put in, and see if anything changes. FA is already changed and CAS and LM have been recoded to accept new FA.

 

For an E60 when you say the FA has been changed that automatically means that CAS and LM have been changed. You need to encode all the units of the vehicle to to accept the new FA. This is important.
