Help required with AUX input

Hi Everyone,

Been a member of the forum for a while now and its a great place to share good things and bad things.

I have done the parrot CK3000 bluetooth install as posted by Delmarco and it has been superb.

I consider myself to be a competent DIYer and do all the basic things like servicing, changing mufflers. control arms, bushes etc myself.

However, I need your help and would appreciate your comments.

I am trying to fit an AUX input lead to my E46's and have a couple of questions as I have done what I think is correct, after searching the forums and taking into account everyones experiences.

I made the leads myself from a radio shack 3.5mm (1/8") to 3.5mm (1/8") so I know these connections are good. For the end which fits to the radio I used part of the parrot wiring loom which wasnt needed for the install. It is a 10 pin connector and fits into the back of the radio perfectly and has been positioned next to the cd changer control using pins 8 & 9 for L/R and pin 4 for ground. All of the connections are perfect, I have checked continuity and resistance with a multi meter and there is no cross over between L/R and ground.

OK here go the questions.

1) Reading some posts it says you need a September 2002 radio to ensure AUX compatability. Mine is a May 2002, has the mode button and has the 10 pins on the back for CD changer control and Aux input. I connected the AUX lead to test, if by chance, I had a freak of nature radio and was AUX compatable. It didnt work.

The question is, if its not AUX compatible why does it have the extra pins in the back? What purpose do they serve?

2) I also have a 2006 coupe fitted with a 2006 date stamped radio. This was a dead cert, or so I thought. Connected the AUX in lead and.......Nothing !!! Used the mode button to scroll through the options and AUX didnt appear. Even when you enter the radio menu to change regions, volumes etc, there was no mention of AUX volume level. Is there anything else I need to do? Some posts mention having a resistor in the lead to allow the radio to enter in AUX mode but then some DIY posts just have the screened cable and end plugs !!

3) Has anyone used the parrot connector to make and AUX lead before and did it work? Has anyone made an AUX lead before and what did they use to connect it to the radio?

I know I can just visit the dealer, pay $$$$ and get a lead but its the principle of paying lots of cash for something which is worth about $6 in parts !!!

If anyone can shed anylight on what they think I have done wrong it would be appreciated. Thanks in advance

You have a UK car and UK radios are made by Philips I think so this may be the descrepency.

Check the parts number NOT the date on the radio to be sure of what it can do.

Also check to see that it is an Alpine Brand Radio and not Philips or Blaupunkt.

Here is my DIY for using the Parts Number to decipher the radio functions:

Quote:
I spent the last 9 months researching for a new MP3 capable unit for my own car and the information below is what I found out.



Here is the complete list of all the BMW Business CD53 Units manufactured and dispatched for the USA E46 cars from 1998 to 2007:

1998 to 2001 E46 3 Series vehicles

Blaupunkt, Part Number 6512-6 909 883 iPod Data Capable
Blaupunkt, Part Number 6512-6 909 882 iPod Data Capable
Blaupunkt, Part Number 6512-6 902 661 iPod Data Capable

NOTE: iPod Data Capable is ONLY if the car is Prewired in the trunk for the CD Changer - You can also add Aux Input ONLY thru an iPod Data Kit like the USA Spec PA12 or the DICE iPod kits


2001 to 2007 E46 3 Series vehicles including the E46 M3


Alpine, Model CD53, Part Number 65. 12-6 916 241 (July 2001) iPod Data Capable
Alpine, Model CD53, Part Number 65. 12-6 915 711 (Sep 2001) Ipod Data Capable

Alpine, Model CD53, Part Number 65. 12-6 919 072 (Dec 2001-Jun 2002)iPod Data, Sirius Capable
Alpine, Model CD53, Part Number 65. 12-6 921 963 (July 2002-Jan 2003)iPod Data, Sirius Capable

Alpine, Model CD53, Part Number 65. 12-6 927 902 (Feb 2003-Aug 2003)iPod Data, Aux and Sirius Capable
Alpine, Model CD53, Part Number 65. 10-6 927 903 (RMFD thru Dec 2006) iPod Data, Aux and Sirius Capable
Alpine, Model CD53, Part Number 65. 12-6 941 505 (Jan 2004) iPod Data, Aux and Sirius Capable
Alpine, Model CD53, Part Number 65. 12-6 941 506 (RMFD thru Dec 2007) iPod Data, Aux and Sirius Capable

Alpine, Model CD53, Part Number 65. 12-6 943 429 (Oct 2004) iPod Data, Aux, Sirius and MP3 Capable
Alpine, Model CD53, Part Number 65. 12-6 943 430 (RMFD thru 2008) iPod Data, Aux, Sirius and MP3 Capable
Alpine, Model CD53, Part Number 65. 12-6 961 215 (Dec 2005-May 2006) iPod Data, Aux, Sirius and MP3 Capable

NOTE: RMFD = Re-manufactured/Refurbished.
If you find any BMW Business CD53 Radio Unit with a production year date sticker on it that is later than these production dates corresponding to each part number unit (IE. a year date that is 05, 06, 07, 08) it is most certain that those units are re-manufactured/refurbished (RFMD) under warranty and re-labeled to reflect the date of re-manufacture. This is especially true for the factory recalled MP3-capable BMW Part Number 65. 12-6 943 429 unit which is always re-labeled to become BMW Part Number 65. 12-6 943 430 after refurbishment.



From that information we see that only three possible BMW Business CD53 Radio Parts Number for the E46 cars has MP3 playback (along with Sirius Integration and Aux-In Data function)

Part Number: 65.12-6 943 429 and it's Re-manufactured/Refurbished counterpart CD53 units with Part Number 65.12-6 943 430. The BMW Part Number: 65.12-6 943 429 CD53s were plagued with problems and there was a factory recall of these units at one point of their hectic production lifespan hence why you come across many BMW Part Number: 65.12-6 943 430 CD53s on eBay today. These 430 units are Re-manufactured/Refurbished versions of the original Part Number: 65.12-6 943 429 Business CD53 Radios even though the sellers of these units either don't know this or won't mention that to you if they do.

AND


Part Number: 65.12-6 961 215 will also give your car MP3 playback ability. These were superior post stock original production units that were made on the last production E46 coupes, convertibles and M3 cars from late 2005 until late 2006/ 2007. If you come across one of these on eBay for under $300 then immediately buy it! These will give you the full capacity and digital function of all the previous CD53 Radios including MP3 playback and it lacks the refurbished and buggy history that the Part Number: 65.12-6 943 429 units come with.


The way the parts number work is that when a said unit gets re-manufactured or refurbished BMW changed the parts number by one up from the original number so say if my parts number unit 65-12-6-943-429 got sent back to the dealership and got refurbished. BMW would restock the same said unit after refurbishment with a parts number of 65-12-6-943-430.

The parts number last three digits increases by 1. So 429 becomes 430 or a P/N 65. 12-6 941 505 radio would now become P/N 65. 12-6 941 506 after refurbishment.

Which is why when you browse REALOEM you will see a lot of strange new P/N come up and some common P/N are not there for the Alpine Business CD53 Radios.

It is possible to find a refurbished P/N with a really late production date like say Dec 2007 or May 2008. Because of this the Production Date of the later years CD53 will tell you little information on what that CD53 unit is capable of. You will need the Parts Number to find out the true identity of that CD53 unit.

NOTE:
They are lots of sellers that try to bump up the price of their Re-manufactured/Re-furbished Part Number: 65.12-6 943 430 units because they will tell you it has a late production date like NOV 05 or something like JAN 07 and the quality or newness is better.

This is to rope you into buying a refurbished unit for more money than those units are actually worth relative to the original Part Number: 65.12-6 943 429 units (which can come with bugs and can be pretty much something you may want to avoid).

I would try to seek out a Part Number: 65.12-6 961 215 unit where ever you decide to buy your unit from.

Even if it a BMW Dealership make sure you ask for the Part Number: 65.12-6 961 215 unit since they may charge you the same price as a 65.12-6 943 430 unit of over $1,000 for it.




Here are some pictures of the Alpine Business CD53 Part Number: 65.12-6 961 215 Radio and the label location where the P/N and Production Date are;





Here is another pristine unit made in May 2006:








In these pictures below you will see how this slick eBay seller tries to peel away the Remanufactured Parts# sticker to reveal the original Parts# beneath so that he can bump up the price. He is selling his units for $309 and $319 based on the prod dates of NOV 04 and FEB 05 respectively claiming the later build date deserves the price increase when both of these units are most likely refurbished versions of their bug ridden/factory recalled Part Number: 65.12-6 943 429 original units.





A general rule of thumb for visually inspecting if the unit has MP3 digital capabilities is that the Business CD53 Radio that play MP3 files usually has the black trim along the same side as the pin17 connector-input that is in the back.





And it should ALWAYS be an Alpine-made unit that has the MODE button in the place of the older Blaupunkt CD button under the AM/FM buttons.

Thanks Delmarco. The radio is an Alpine unit which I purchased from another forum member from the US. Will pull it and check the part number against your descriptions above.
Again, thanks for your help.

The aux cable itself will not be detected by the radio & will therefore not be a selectable input. To have the input show up when you press the mode button, you either need to have something plugged into the other end of the aux cable (e.g. iPod, Zune, Discman, etc.) or wire up two 0.22 microfarad capacitors & a 300 kOhm resistor in the same way as the OEM cable (diagram here). That's why you've seen "successful" aux input DIYs either have or not have the caps & resistor included; it'll work either way, but only when you have something plugged in. (It is worth noting, though, that without the caps & resistor package you will not be able to charge your iPod/iPhone while it is connected to the aux input; the radio somehow detects that it's connected to a powered device on pins that aren't supposed to be powered & internally disconnects the aux input.)

Much more info can be found here: Let's DIY aux input cable

Hi guys
I have an '01 E46 with Mode button. Mine too does not show the AUX option when i press the button. Only CD and Radio come up.
According to the post above, if i do the DIY, hence just plug the cable in the back with a 10pin connector, the AUX option will show up when i plug my phone. Right? Even without adding capacitors etc.

Also, has anyone used the ebay ready to install packages people offer for around $10-$20?
Any of these:
BMW Female AUX Audio Adapter Cable E46 Business CD Charger For iPod iPhone 5 5S


BMW E46 AUX IN IPOD ADAPTER KABEL RADIO CD AUTORADIO

First thing you should do is check your head unit and make sure you have the pins.



Second, I'd stay from those eBay kits. You can either make one yourself or get the OEM kit at like 10 bucks more. That ten extra dollars, think of it as an insurance policy if you have any issues.

If I have the pins ( which I guess I'll find on some diy somewhere or in another page), will the AUX work just by adding the wire?
