Retro fitting VW Aux-in Lead Golf MK5

[RC01]

Thanks for the info.

I have a 2004 Golf (which i think is 1K) with the standard RCD300 (all black facia). So the information you have provided would suggest the kit it not intended for older units. I guess it would fit into the CD changer input but i would need to confirm with the dealer as to whether they can activate the aux function. Bearing in mind you say that there is nothing to set the RCD300 apart from the 500 and that they would have the cd changer input for show....

Once again I greatly appreciate your input. Will see how it goes.

Cheers.

It would make sense if this only works with the 2007MY onwards 'silver button' head-units, as that was when an AUX socket became an optional extra on the price list.

See http://www.michaelneuhaus.de/golf5/golf5modjahr.htm "New Option: Multimedia socket for external audio sources"

In the UK this was a £25 factory option

When using this connector the display will show "AUX IN":



... but with the connects2 the display will just see it as a cd changer:


This is all in theory though, I've only ever used the official iPod adaptor, not the above two setups.

Hi all,

Ive just been to the VW dealer, told them details of car (2004, RCD 300) i was advised that the stereo aux function wouldnt need activating and just to purchase the parts (1K0 998 940), ie, plug n play. I explained to them that I think it does need activating and I currently dont have a CD changer or Multimedia Interface, etc. Advisor then said to activate the function it would cost £40 (just to activate and no fitting of 1K0 998 940). The parts dept advised that 1K0 998 940 kit costs £30.

Not too sure whether they know whats going on and so would rather not pay £40 + when they are unsure themselves whereas £17 i think would of been reasonable.

Decided to look into buying CTAVGUSB009 from Connects2 which has usb and 3.5mm jack input and comes with a usb stick for £61 (£53.99 + £7 delivery)...

Question is will I still need the cd changer/Aux function activating... Is there not specific coding that needs to be changed that anyone knows as my local garage has VCDS and would do it for probably 5-10 quid if not free.

I did look at getting one of those units too but i was put of by reviews (not that i can remember where) plus i guess you can't navigate usb content?

At least the part(s) is the same price, I got mine form Vindis Miltion Cambs after spending ages looking for the part no. off my own back and then took it to Vindis VW Sawston Cambs to do the aux enable for 15.63+VAT.

I was told (on one forum, maybe this one) that unless the radio has had something already working in the aux in socket then it will need turning on, this was unknown on mine because it was secondhand (08 radio in '54 plate car) once all installed it didnt work hence trip to dealer. It took then a mater of minutes while I waited!

I'd phone them to compare, if your dealer says it will work without enable then get them to write it down and hold them to it

I went to my local VW specialist who with a bit of help activated the CD changer/ipod option using VCDS for free. Now if i press the "CD" button twice it trys to search for a CD changer...says "no CDC" the the moment....half way there i hope...bit impatiant so trying to find a way of testing it before I get any cable to see if it actually does work...

The connections i have are as follows:

Pin
1 = clock
2 = Data in
3 = CDC Switch
4 = CD-R
5 = CD-L
6 = not used
7 = Data Out
8 = not used
9 = +Ub CDC
10 = not used
11 = EARTH
12 = not used

i have a connector and 3.5mm cable...etc just unsure of how to connect it all. ..to test whether all this will actually work or not.

It only uses 3 connections, The instructions refer to them as follows:

Within the plug,
Chamber 2 Gray = GND
Chamber 8 Yellow = Left CH
Chamber 9 Green = Right CH

I fit the oem aux in
Attachment 8625
1 - Audio signal, left
2 - Voltage supply, terminal 31, negative
3 - Audio signal, right

pretty simple no coding should be required or if it is just add aux in
if adding a ipod player it just simulates the 6 disc and should just plug and play

Cheers guys,

Ive tried kev's method which I have assumed to be two audio inputs into CD-L and CD-R with a earth also. Would i make a difference in short term if not earthed correctly as i have tried this and it has not worked. When i select CD twice it still just says "No CDC"..then goes back to built in CD.

A8tech..which headunit is that diagram intended for, dont seem to recognise what it is. Although your wiring method seems to be same as Kev's. I have RCD300 (without MP3, and not with silver buttons), never had a cd changer or ipod interface connected. Just had the CD changer/Ipod function activated today. Now I am able to press CD button twice for HU to attempt to connect to CDC.

[RC01]

this is how i have tried wiring so far..
Audio input left and right into CD-R & L with an earth directly beneath the connection for CD-L. (pic is borrowed)

RC01: the picture you posted matches up from both my old RCD300 and new RCD 500 HU.

The picture a8 tech has posted is the socket of the aux in connection, that goes in to the glove box (replaces the light) this is where one end of the aux in lead plugs in to (little black plug on my original pictures on this post) the blue 10 pin plug goes in the HU.

The earth has to be connected to the main earth of the HU harness, the kit comes with a special connector, again in the original pics.

When my aux in is selected it says AUX, not CDC etc. I have the built in changer.

I don't understand why CDC being displayed
