This is WRONG info! The prodution date has little to do with anything when it comes to buying a quality unit. 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.


Only two BMW Business CD53 Radio Parts Number for the E46 cars has MP3 playback (along with Sirius and Aux dual data Datalink inputs.)

Part Number: 65.12-6 943 429 (and it's Remanufactured/Refurbished counterpart CD53 units with Part # 65.12-6 943 430). The BMW Part Number: 65.12-6 943 429 CD53s were plauged with many many many problems and there was even 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 are Remanufactured/Refurbished versions of the original Part Number: 65.12-6 943 429 Business CD53 Radios even though the sellers of these units won't mention that to you.

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.

NOTE:
They are lots of sellers that try to bump up the price of their Reman/Refurb
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 pretty much scam 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 of over $1,000 for it.




Here is some pictures of the Superior CD53 Part Number: 65.12-6 961 215 Radio and their respective labels;

I just bought this unit on eBay for my car with this sticker on the bottom. (I was lucky to find it for $200 BUY IT NOW) :



Here is another pristine unit made in May 06 that is on eBay right now for $298:








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 connectior-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.

A little more info to add on



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 Cars
Blaupunkt, Part Number 6512-6 909 883
Blaupunkt, Part Number 6512-6 909 882
Blaupunkt, Part Number 6512-6 902 661

2001 to 2007 E46 Cars including the M3
Alpine, Model CD53, Part Number 65. 12-6 916 241 (July 2001)
Alpine, Model CD53, Part Number 65. 12-6 915 711 (Sep 2001)
Alpine, Model CD53, Part Number 65. 12-6 919 072 (Dec 2001-Jun 2002)
Alpine, Model CD53, Part Number 65. 12-6 921 963 (July 2002-Jan 2003)
Alpine, Model CD53, Part Number 65. 12-6 927 902 (Feb 2003-Aug 2003)
Alpine, Model CD53, Part Number 65. 12-6 941 505 (Jan 2004)
Alpine, Model CD53, Part Number 65. 12-6 943 429 (Oct 2004) MP3 Capable
Alpine, Model CD53, Part Number 65. 12-6 961 215 (Dec 2005-May 2006) MP3 Capable

NOTE: 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 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.

I have MY2002 330xi which came with HK audio.

Recently the business CD player died, and dealer replaced with

65-12-6-961-215 RMFD radio.

Doesn't sound nearly as good as original unit.

Just wondering if anyone can answer if the business CD head units are the same for the HK and regular audio systems?

I know HK has different amp, subwoofer, and perhaps speakers but can't tell about head unit itself. Was there perhaps a change of Manufacturer of these head units since early 2002 to now? Or perhaps it just doesn't match up as well with the amp and speakers from MY 2002 as it's a (newer?) head unit?

I have about 2 weeks left on parts warranty for this car....

thanks v. much

I know this reply is about 5 years later. But I found this thread from a basic Google search seeking information on resetting my 65-12-6-961-215 unit for the USA region that I bought on eBay .

HOW TO RESET and CALIBRATE YOUR BMW BUSINESS CD53 RADIO: With the engine/car off and key in position 1, turn your Radio on and hold down the M button until some funny numbers show up with - + in the RDS/PTY screen area. Use the buttons you would normally press for RDS and PTY to scroll thru the various settings and information.

Some of the information you will scroll thru are S/N serial number, build date of unit, parts number, SW number and the rest are basically settings that you can change. You will see one for REGION (I think USA or EUROPE come up) and you can properly select your REGION. Also one of the settings seem to be for adjusting your Radio's antenna's AM/FM frequency. I think this was labeled V or something and it allows you to increase or decrease the antenna sensitivity.

They are a bunch more settings that I haven't explored. But setting my REGION correctly and calibrating my Antenna sensitivity made everything better for my 65-12-6-961-215 unit and yes it does play MP3 Data CDs.

Also 65-12-6-961-215 is not a designated Re-manufactured parts. On the dealership computer that number comes up as an original manufacture part.

The way the parts number work is that when a said unit gets re-manufactured or refurbished BMW changed the parts number of the said unit to a new number relevant to 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 ending three digits increases by 1. So 429 becomes 430.

or a 65. 12-6 941 505 would now become 65. 12-6 941 506 after refurbishment. Which is why when you browse REALOEM you see a lot of strange yet familiar looking parts number.

Here is a list of ALL original parts number for the BMW Business CD53 Radios;

1998 to 2001 E46 Cars
Blaupunkt, Part Number 6512-6 909 883
Blaupunkt, Part Number 6512-6 909 882
Blaupunkt, Part Number 6512-6 902 661

2001 to 2007 E46 Cars including the M3
Alpine, Model CD53, Part Number 65. 12-6 916 241 (July 2001)
Alpine, Model CD53, Part Number 65. 12-6 915 711 (Sep 2001)
Alpine, Model CD53, Part Number 65. 12-6 919 072 (Dec 2001-Jun 2002)

So easy to make people out to be a 'bad guy'. This seller would NEVER peel away the part number. "slick"? Give me a break.

Ohhhh believe me I have all rights to finger them!

I have had lots of experience with that seller. When I owned an E36 a few years ago I bought a CD43 Radio from them for almost $400 thinking it was original and OEM and new condition.

What I got was something else with a 5 cent Hello Kitty-like bubble ///M sticker on the front that was supposedly covering a Range Rover Logo or something ghastly that I can't recall.

I didn't even want to install it when I saw what he shipped but I did anyway to see where my $400 went.

The thing skipped discs and/or didn't play burned discs at all-something like that.

In the end I pretty much paid $400 for a Hello Hitty bubble ///M sticker attached to a piece of junk metal!

When I got rid of that crap and go to bid on an actual OEM unit guess what the seller is doing...
