Folks,
I've already purchased a pnp adaptor from Lanny. I was just curious, can someone help me out with some wire/pins that I am unfamiliar with? Keep in mind, I have a 2001 A6 (non-bose, CD changer and telephone)..so I'll be running the CAN H/L from the instrument cluster.

I've searched the forum to find the answers already...but I still have some outstanding questions. See below for my "?'s" on connector's B, C and D. I'm cool with connector A (pretty straight forward) and the 32 pin A/V interface (won't be fiddling with that).

Thanks!

A: Speaker Connecter (front passive speakers)
1 - N.C. (NC = Not Connected)
2 - Right Front (+) (ok)
3 - Left Front (+) (ok)
4 - N.C.
5 - N.C.
6 - Right Front (-) (ok)
7 - Left Front (-) (ok)

B. EXT Control Connector (CD Changer, PhatBox, OEM SAT tuner, Dension IceLink etc.)
1 - Most Ring break (Used for MOST network diagnostics to "break" the MOST ring; This will never be used in any RNS-E install to date)
2 - CDC-NF GND (audio ground for CD changer; this should NOT be connected to any chassis ground source)
3 - V-Signal (analog speed signal or GALA in B5, C5 and D2 chassis)
4 - U14R-2 (Constant power source for CD changer, phatbox, oem or aftermarket ipod interface etc)
5 - K-Line (K-line diagnostic; needed to configure your RNS-E via a VAGCOM)
6 - CDC-Data out (ok)
7 - *BOSE Pin (used if you have a Bose system)
8 - CDC-NF L.IN (ok)
9 - CDC-NF R. IN (ok)
10 - U14 ST CDC (Ignition/accessory power for CD changer, phatbox, oem or aftermarket ipod interface etc)
11 - CDC -Data IN (ok)
12 - CDC- Data CLK (ok)
*The Bose pin was commonly found in the B6/B7 A4s, C5 A6 and D2 A8's with a model year of 2002+. This should be connected to the bose pin in your factory harness. Per Lee Hicks (NSX Jr): This should be connected to ground if you have a BOSE system. I tried it both ways, and it sounds WAY better when grounded... obviously only if you have the BOSE system. By grounding, you tell the RNS to use a different audio equalization and processing before it sends out the signals to the amp.

C: EXT Control Connector (For Bose or Non-Bose Amp, telephone interface)
1 - **MIC IN (-) (Used for OEM Bluetooth kit when SDS is factory installed)
2 - *RFSL (Analog reverse signal)
3 - Line Out FL (front left audio signal)
4 - **MIC Out (-) (Used for OEM Bluetooth kit when SDS is factory installed)
5 - Line Out RL (rear left audio signal)
6 - TEL NF IN (-) (Telephone speaker negative input)
7 - **MIC IN (+) (Used for OEM Bluetooth kit when SDS is factory installed)
8 - Line Out GND (audio ground)
9 - Line Out FR (front rear audio signal)
10 - **MIC Out (+) (Used for OEM Bluetooth kit when SDS is factory installed)
11 - Line Out RR (rear right audio signal)
12 TEL NF IN (+) (Telephone speaker positive input)
*Reverse wire: C5 A6, B5 A4/S4 and D2 A8 use an analog signal for reverse. Most harnesses won't have this connection available...so you will need to add a female pin/wire (part#000-979-009) and route it to reverse signal near the drivers' side lower dash area (see www.nsxjr.com for location of reverse signal in a C5 A6).
**SDS (Speach Dialog System) will need to be factory installed (found in B7 A4/S4 for example) in order to take advantage of these mic in/out wires. If no SDS, then you will connect the mic wires directly between your OEM bluetooth kit and the BT mic that you install near your sunroof controls.

D: Power Connector
9 - CAN-H (CANbus High signal)
10 - CAN-L (CANbus Low signal)
11 - TEL-Mute (Telephone mute connection)
12 - Kl.31 (Primary ground connection)
13 - U14 ST DSP (Radio On) (Provides a switched ignition-out source to turn on rear amplifier (bose too) or "remote" lead for an aftermarket amp)
*14 - DWA-GND (Alarm ground)
15 - Kl.30 (Constant 12V power source)
16 - U14R-1 (N.C.)
*This is the Alarm-GND pin. This pin should be connected to Connector I, pin 2 from symphony II radio harness, or to the large brown single pin connector from behind the symphony I radio (see the pdf docs on www.nsxjr.com for related pictures). Chances are, you will need to add this female wire/pin (audi part#000-979-133) to your plug/play harness and and male wire/pin (sorry, no audi part# for this; some of us will have extra's laying around).

32 Pin Connector: (A/V interface; Dietz 1417/1280/1215 and OEM TV Tuner)
1 - N.C.
2 - N.C.
3 - N.C.
4 - N.C.

15 - IN-Sync
16 - IN-G
17 - N.C.
18 - N.C.

Not all the RNS-E models are using all the pins, although the diagram always shows all the pins. The famous 4B0 speed wire is a good example.

Based on this, nobody has posted so far information about the Most Ring break pin, U14R-1 or U14R-2. Some guessed that U14 ST CDC has something to do with the CD changer but I haven't seen final confirmation on its use. Same for RFSL, some said it could be Reverse but the RNS-E gets reverse always over CAN. U14 ST DSP is the switched 12V for the Bose or active sound system (IIRC), the RNS-E gets the ignition signal always over CAN. DWA-GND is something related to the car alarm (DWA = Diebstahl Warnanlage), I would need to check my adapter to see if it is grounded or not. K-Line is the k line, without it you won't be able to configure your RNS-E.

That's what I recall right now...

Great thanks. I've updated the original post above based on your input.

I suppose that not all RNS-E pins are used for every install. As I recall, the B5 A4/S4, C5 A6 (pre 2002) using a Symphony I did not have the wire for "Alarm"....but in the B6 A4/S4 and post-2002 C5 A6 did have the "Alarm" wire.

Even in the Nav+, there were some pins in the 26 pin connector that no body knew what they did. There was an OEM digital "log book" that was an option for the Nav+ (RNS-D)...but we never knew how it hooked up to the head unit.

Thanks again for the input. It's helpful to know what each of these pins do...if I need to troubleshoot my install.

BTW: do you think it would be possible to hook a camera to the back plate and have the RNS-E activate the AV1 input when the reverse gear is inserted ???

I though that connection would be meant for such purpouses...

LEXUS cars have such option and I suppose the engineering of the device (=AISIN) is not very far from there... ;-)

Just dreaming weird things during the night, to be wrote on the forum... :wink:

Ciao

my friends Acura also switches to rear view camera (and tilts the passenger mirror down) when placed in Reverse.. maybe Audi has the capability as well..


we should add the descriptions to the pin-outs thread in the Quick Links..

Which PNP Harness do I need?

Hi,
My 2006 A4 supposedly has the BOSE Symphony II but from what I can tell, all of the PNP harnesses on www.euro-parts.us that have BOSE sound option do not include the brown front channels speaker connector that I have in my car. I specified that I had a BOSE Symp2 and also wanted to be able to add a phone and cd changer in the future and was sent a PNP Harness that looked like this https://www.euro-parts.us/image.php?productid=16136.

Is it possible to use this connector in my car? Do I need an adapter that has the brown plug?

I would appreciate any help please.

Thank you

The 8 pin speaker connector is only required if you don't have Bose. If you have an 8 pin plug with 4 pin used, then you probably don't have Bose. Can you make a picture of the plugs going to your Symphony II to confirm what you got?

I agree with the above statement. If you have the brown 8-pin connector in your B7, then you don't have BOSE amp and speakers.

You need a completely different pnp adaptor. There are more wiring differences between the two adaptors....beyond just that brown 8 pin connector. Time to reorder. Good luck!

Folks,
I've updated the information on the RNS-E pin-outs to reflect all the new developments over the past 4 months. I just don't want the info in the quicklinks section to be outdated or misleading.

Special thanks to Lee Hicks (NSX Jr) for discovering all of these inconsistencies with the commercially available plug and play harnesses. I've incorporated all of his findings back into this thread.
http://www.navplus.us/forum/viewtopic.php?t=1418

Lee/Dirk/Alex: Please let me know if any of my changes are incorrect...and I will fix.

Bottom-line: While the plug/play harnesses certainly can simplify the installation process, you should still plan on making some minor modifications to make the harness specific to your own vehicle needs. Some of you in north america have already started to contact me to help in this effort (which I am glad to do) :D

Can any of you technically-inclined folks translate these pinouts to a schematic that maps Symphony II pins to RNS-E?

I ask this because my battery died over the course of the install, and because I know I found at least one pair of crossed wires going to the Bluetooth interface.

I don't have the skills to make a decent harness, but it's definitely worth my time to trace the wires between the connectors, if only there was a simple diagram or table for guidance. "Trust but verify," I suppose.

BTW, this forum has been an absolute lifesaver -- a real wealth of knowledge. I simply couldn't have done it without all the info on this site.

Thanks -- that's pretty much what I'm after. Could still use some elaboration ("If you don't have Bose, you shouldn't have this wire," etc.), but it's a great starting point if you need to check a harness.

Strange thing...

Added RNS-E and was in the process of adding the CAN wires when I noticed I had CAN wires in the appropriate pins on the 20 pin connector. Moreover, I turned the RNS-E on with the lights, and it lit up.

This is with a 2001 2.7T C5 BTW. Any comments?

Did your car have the trunk mounted CD nav unit? If so, that explains the infotainment CAN wires although they don't always extend to the radio.

Very odd. Must be a late build 2001 model year. This is very rare. If you have the MF steering wheel, I would be curious to know if that is functional as well (without upgrading the MF control module).

After "pinging"the CAN, I noticed that pins 8 and 9 on connector 1 were not connected to the CAN. I think the previous owner had an RNS-E, and left some connections there, but attempted to return to OE state. The lights were intermittent, which I cannot explain. After making the connection to the CAN however, they work consistently, showing the lights on the radio before were at the very least, improper.

The MFSW of course does not work, but an interesting fact. When I procured the vehicle, the MFSW did not work and Audi replaced the steering wheel and modules under warranty. I suspect the owner had the the "F" module- am not too sure though.

Hi,

You said in the above forum:

K-Line is the k line, without it you won't be able to configure your RNS-E.
If you have can h and low on your audi a4 b6 2002, I don't have to do something with the k line right? Because everything goes to can H and L, you just explained me...

Thanks,

Martijn
