AH, The tuner as got 17 round pins connector ,but the ng sat/nav wiring loom as got the flat pins,and is it possible to get an adapter to change one to another, or splice one on.

I think you can get a convertor, not sure about the 2 smaller (10/12 pin) plugs that plug into the bottom of the big radio module plug though, you may also need to convert them too.

You could probably make a 17 round pin to 40 quadlock convertor out of two SOT leads, It would cost about £15/£20, (fairly straight forward, if you're handy with a soldering iron).

Or replace the tuner for a newer BM54.

I doubt the radio will be different, I can think of no reason why the Rover radio should have different firmware in it to a BMW radio, apart from the age of the radio (given that development of Rover units stopped when BMW sold Rover to Ford)

So a BMW radio will have newer firmware than Rover.

eg: if you want to use a BM24, use one with software version v9.0 or later (I have v10.0) for full compatibility with the Mk4 nav. Earlier versions work but produce undesirable effects at times, like switching to the radio screen for no apparent reason!

Hi Jochen ,your are right again :- brand new BMW (phillips) RDS Business radio.

Part Number : 65 12 8 382 364

Other numbers on the radio include:

PH7851W1142900

KW 9820

INDEX : 00

This radio will fit most:

BMW

• 7' (E38)
• 3' (E46)
  
• 5' (E39)

Radio will fit on vehicle's with satellite navigation display Well it looks like my tuner is the C23 made by siemens,and the sat/nav computer is the MK 111 as it as got the purple and blue wiring plugs ,with the LR/MGR software ,which won't load the bmw updates.
On the E46 sat/nav retriofit wiring loom there is a black three pin connection the colours are yellow black and brown ,could you tell me what they for and what they are connected to,here's a photo
http://img.photobucket.com/albums/v3...2_edited-1.jpg

3-pin connector: =AUX_IN connector, X14118

Black = AUX_RE+ (right) = Pin 1
Yellow = AUX_LI+ (left) = Pin 2
Brown = AUX_GND (ground) = Pin 3

Connected to the radio (N9) on connector X13649

Thanks you KiwiJochen, but can you tell me if the ROVER / BMW (phillips) RDS Business radio/tuner had the cd changer connection, and if it did can you tell me the wiring pins connection colours and numbers please.

I'm also looking for the pinouts of the alpine cd changer xqe 105560 from a rover 75 to plug it to my 2001 e39 bmw. anyone has done this before ?

the wiring of the cd changer is as follows:


1. yellow
2. black
3. red ( or pink )
4. white
5. green
6. blue_1
7. blue_2
8. brown
