Hello, bimmerfans,

need Your help. On my bimmer (2001 year) originaly was instaled "BMW reverse" radio/cassete player. Now i want to change it to "BMW Business CD", but i faced one problem: "BMW reverse" is one big part and it has one connector, meanwhile "BMW businees" consists of two parts - cd player and MID (both have connections).
Does anybody can offer any solutions?

Sorry, for my not very fluent english.

Unfortunately 95% of the people here are from North America where we were not given this single-unit stereo; only the tape/cd and MID came in the cars sent here...so most are unaware of that type of radio and I've never seen it either. There might be some type of wiring harness available for this but not needing it I'm unaware of it...

In first image what is instaled originaly http://bmw.e39.hu/radio/ReverseRDS2G.jpg, on the second image http://bmw.e39.hu/radio/BusinessCD_MIDG.jpg is with what would be replaced. At the moment do not have the tool to remove instaled player to make photos of the back and connection.
Here's link where You can see that Business CD consists of two parts http://www.realoem.com/bmw/partgrp.do?model=DT11&mospid=47538&hg=65&fg=05

Yes, You are right.


i think there is some adaptors required for this conversion. i think the part number you require is (BMW adaptor 61-12-6-913-957)

where simply you will plug the new CD to this converter

check this thread for more info:

Hello

I bought an adaptor (part Nr.65 12 9 405 409), but have no idea which end of adaptor where leads and how to connect cd part with mid part :) On one end of adaptor is "plug-&-play" connection (is that how i would call it), and the other end of adaptor is free wires whith some kind of plugs. "The right end" connection has 12 holes and 1, 2, 3, 4, 8 holes are fitted by wires 1st - brown-black (as i understand this might be ground "-"), and about other 4 wires do not have any clues.
So colegues, may somebody of You have instalation guide?
Thax a lot
