    Can I do a BMW Aux Install?

    Ok so I have a 2002 525i with Business CD and I want to know if I can do the BMW aux audio port install? Ive read that it can only be done on 03+ BMWs and I have also read that people have done it on some 02 BMWs... If this is possible can someone point me to a write up about doing it on an 02? Thanks.

    Check build date of your car - aux input instructions state that the kit works for cars 9/02 and later. Here are the installation instructions from BMW:

    I can't believe I've had my 528iA sport 14 years and counting . . .

    4 BMWs.
    if it''s a 9/02 car that makes it MY 2003 so probably not, but check as MNsport suggests.

    The OEM kit only works with 9/02 and newer - but as xisco44 mentions there are other kits for aux input that use the CD changer connection (Blitzsafe, DICE and others). Hopefully you can use the OEM kit as it is only about $35 (P/N 82110149390), otherwise check DICE/Blitzsafe and there are others...

    nope i use the oem kit on my 96 e39
    is easy take out your head unit unplug the cd changer and plug the oem adapter.
    now put a disc on the cd changer , so it fool the head unit that the radio is playing something voila.
    aux in in your car.

    if you want you can make your aux input adapter for like 5 dollars with radio shack parts.

    Is there a DIY for that? My CD changer is in the trunk, is it possible to use the cassette connections for AUX? I remember seeing someone do it like that, but it didn't have instructions on how to remove the radio (the top part with the sliding door)..
    Thanks in advance

    My CD changer still works after the AUX install. Now, i've got the single Cd, the changer, radio, and AUX. They all work. I did make sure that mine was post 9/02 when i purchased though. maybe for pre-9/02's the aux will still work, but you lose the changer. I dunno.

    OP, just purchase the OEM cable like Xisco and I did. $35, completely pnp. report back whether or not your changer works afterwards.

    There is a way to hook it up to the casette. it "tricks" it. Here's the link...

    you just need to get a 1/8 aux in female jack and a cable with ground + and - and check
    for the ground positive and negative on your head unit.

    this pic is the diagram of the aux in kit that bmw sell. you dont need to use the capacitors i use them on my car at the beginning but later on i rip them apart because of low bass.


    }


    thats my headunit

    i did loose the cd changer but who cares

    i make one of my own exactly the same as oem with capacitors and filters and everything.
    later on i rip apart the capacitors cuz they were messing with the bass coming out of my ipod

    Update: My cars build date is actually 11/01, so according to the stealership (which I talked to today) the oem aux input upgrade can only be installed on BMWs with build dates of 9/02 or later... However the parts guy also said that the reason it could not be installed on BMWs newer then 09/02 was because it could only be installed on the Business CD stereos. That said my car does have the Business CD player (it says "Business CD" on the CD player). So my question is was there a difference between the Business CD stereo in pre 9/02 models? Or are they the same and should have the same inputs? Also does anyone have a write up on how to remove the radio so I can just look to see if it has the proper input? Thanks.

    dude if you have a cd changer you can put the aux in cable

    go to google and search

    if i did on my old 96 e39 you can do it on your 01 dont believe what the stealership tell you.

    how to do the aux in cable



    now get a pinout of your radio this the older one



    your cd radio should have to conector on the back

    on for your cd changer
    and other one that have nothing plugged in.

    if you only have one for the cd changer unplug the cd changer
    and look for the pinout

    right cd changer
    left cd changer
    and a ground

    but first take your radio out and check if you have one or 2 input

    you can check on youtube how to remove an e39 headunit
    no rocket science you can do it in 5 min with a torx 10

    Xisco, Thanks for the info. I don't have a CD changer just the single CD player in the dash... Does this all still apply? Also I heard a rummer that the Business CD player can play mp3s is this correct or is it only on later years? Thanks.

    Hello Xisco,

    I have a BMW e46 from 1999

    I wanna connect a MP3 jack at the back from my radio so i can connect my MP3 on my radio, but i have only 1 input this has 5 Pins(i can see you have 10pins) and i have no cd changer.

    I have a picture if you want.

    Do you know how that i can connect this at the back of my radio?

    I will be very happy if you can help me.
