View Full Version : DIY: Symphony II to RNS-E (OEM DVD based Navigation)

08-14-2005, 08:34 PM
This write-up documents the process of upgrading from Symphony II to an RNS-E whether it's a Euro unit (8E0 035 192 C & D) or a US unit (8E0 035 192 E & F).

for a complete list of all the differences btw a Euro unit and a NA unit, please check this thread (http://www.navplus.us/forum/viewtopic.php?t=238) on NavPlus... be aware that the price is significantly different btw a Euro unit (US$1,500) vs. a US unit ($2,000+), however apparently it is possible to modify a Euro unit to operate like a US unit (see the following NavPlus thread (http://www.navplus.us/forum/viewtopic.php?t=751)).

please note that you will need a patch NA map DVD to work with the Euro RNS-E...

i cannot guaranty these instructions may be applicable to those upgrading from a manufactory installed RNS-D (partial or full)...

although such upgrade might appear daunting, it is absolutely not. no electronic skills are required to perform this upgrade, no mechanical skills either. the whole process is really straight forward.


the actual shape of the Symphony II and RNS-E (and RNS-D) is the same, thus the RNS-E fits right in the opening of the Symphony II w/o the need for any kind of modifications... that's indeed another story of you've got a Symphony I...

further to an RNS-E unit the following parts are needed:

- RNS-E adaptor:


this adaptor is designed for a non-Bose system and is ready for the CD changer... make sure you order the adaptor that meets your needs.

- Diversity and Radio antennas adaptor:



be aware there's another style of adaptors out there, but i would recommend not getting this one... if you do, you'll have to find a way to secure the diversity antenna in its connector, and the Radio antenna adaptor will need to be jammed in to stay plugged in...
i had that adaptor at first, and decided to get the dual one, which fits perfectly... so imo, avoid the one pictured below...


- GPS antenna:


here's a couple of places where you can source these from:
. AudiZine classifieds (http://www.audizine.com/forum/showthread.php?s=&threadid=52256)
. NavPlus classifieds (http://www.navplus.us/forum/viewforum.php?f=11)
. Euro-Parts (http://www.euro-parts.us/) in the States - run by BayrischerS4 from NavPlus
. Kufatec (http://shop.kufatec.de/) in Germany - beware of shipping costs (http://images54.fotki.com/v551/photos/1/110342/2240739/RNSEUnitKufatecInvoice-vi.jpg)...

- OEM Manuals:
these can be obtained from Audi of America and Audi Canada Technical Literature Ordering Center (http://www.audi.ddsltd.com/), and at US$5 per publication, these are quite cheap imo...

Now on to the actual process of installing the RNS-E unit...

i believe the pics are self explanatory, especially since i've annotated all of them... i also apologise in advance to all the purists out there if i have not used the proper terminology!!!...

- GPS Antenna:



- GPS Antenna Location:


- RNS-E Connections:



- CD Changer Connections:

wire the CD Changer harness (part number: 8E0 051 592) following the instructions provided w/ the harness w/ the only exception that the wires should be plugged in directly the Connector #1, do not use the connectors provided w/ the harness... then as far as the ground wire goes follow the instructions below...



finally the next step is to VAG the car (http://docs.google.com/viewer?a=v&pid=sites&srcid=b2dkZW5sYWJzLmNvbXxhdWRpfGd4OjY2YWZiZWJlN2U2 MjgwMGM) so that it acknowledges the RNS-E unit... accessing "Module 17 - Instrument Cluster" isn't necessary if you've already had an RNS-D installed and programmed before...

now time to put your car back together, so just follow the above instructions in the reverse order...

for those of you looking for the pics, i had to switch internet providers and unfortunately the pics went down by doing so... but you can still see all of them by checking out my corresponding "Symphony II to RNS-D to RNS-E" Fotki album (http://public.fotki.com/Avanteix/audi/my_avant/goodies/interior/nav/symp_ii_rns_d_rns_e/)... the pics are stored in the order of the installation iirc...

03-25-2010, 02:40 PM
Alright, finally got around to re-linking all the pictures...

03-25-2010, 05:22 PM
Wow, not sure how i missed this post when i just did mine, this is great! Thanks for the link to the manual. I have a Q unit in my B7 S4. Do you happen to know which manual want?

Alright, finally got around to re-linking all the pictures...

I was just about to say, "wow, pics are working now?!" Awesome tutorial

awesome writeup, where can I get these wiring harnesses and also antenna adapters...Also I have BOSE, they make an adapter for it as well?

Wow, great post. Love the details including the pictures. Definitely will have to give this a go one of these coming months.

I have a question about the harness; Do the passive front speak connectors have the same connection on both sides? Could i run the symphony connector straight into the RNSE? I have a bose adapter, but a non bose car.

Where can you buy wiring to run the GPS Antenna from the RNS-E unit to the shark fin on the roof?

10-05-2012, 06:27 PM
I recently did this upgrade on my 2004 B6 A4 and thought it might be worthwhile to add a couple of things.

GPS Antenna

If you have a car with a shark fin antenna you should skip the bolt-on antenna and wire up the existing antenna instead. It will get you superior GPS reception. All you need is a Duplex FAKRA to FAKRA extension cable. I got mine from the good folks at Kufatec (http://www.kufatec.com/index.php?main_page=product_info&cPath=188_144_93&products_id=171&zenid=fb2lm1oafbja923rfbn7tn2ht7). The installation is pretty straightforward. See this thread (http://www.euroaddiction.net/forum/b7-a4-diy-how-section/577-audi-b7-a4-diy-installing-gps-extension-cable-sharkfin-antenna.html) for details (it's for the B7, but the steps are identical for B6's).

BOSE Harness Issues

I received my harness with the RNS-E and the supplier assured me that it was compatible with my BOSE setup. It turned out it wasn't and it took some effort to diagnose what's going on. Even though the head unit appeared to work fine, my battery would wind up depleted the next morning. With most of the troubleshooting information out there being somewhat dated by now - including many dead links to non-existing images and documents - it took some effort to figure it out. I ended up performing the steps below, which effectively allow you to convert a non-BOSE harness into a BOSE harness.

If you installed an RNS-E BOSE setup that appears to work (functions as expected, coded correctly and no fault codes), you should go through the following simple steps to make sure you don't have any hidden issues or a non-matching harness. To diagnose and trace wiring use this handy document (http://www.daveg6hni.f9.co.uk/Downloads_Audi/Audi%20-%20RNStoSym2.pdf) as your guide. It's pure gold (note: with BOSE and B6s you can safely ignore Connector A, pins B3 and C2).

Verify you don't have any EQ Gala settings in the RNS-E sound setup. If you do, check your coding (0xx9xxx for BOSE) and adaptation values (255 in adaptation channel 8) and that the BOSE pin (B7) is wired correctly.
Sit in the car, remove the ignition key and lock the doors with the key. The RNS-E should keep running in standby (screen off) for exactly one minute, then power down completely. The BOSE amplifier should power off at the same time. You should hear a distinct 'power-off' sound coming from the speakers, followed by complete silence. If, after a minute, the RNS-E is not completely shut down or you still hear a bit of amplifier background noise (very faint buzz) coming from your speakers you have a problem. If this is the case, verify that...

Alarm Ground (D14) is wired to III-2 (faulty wiring results in the RNS-E not noticing when you lock your car and it will keep on running in standby for a lot longer)
Amp Power (D13) is wired to I-6 (faulty wiring results in your amplifier never turning off even when the head unit does)
Main Power (D15) is only wired to III-7 and not bridged to any other power-related pins such as B4/I-16, B10/I-17 or D13/I-6 on either side of the harness (faulty or bridged wiring may result in your amplifier directly drawing power from the battery and never turning off).

Make sure you don't get any fault codes after making any of these changes.

To fix my wiring issues, I harvested unused wires and terminals, including RNS connector A (non BOSE audio), Symphony connector II (non BOSE audio) and any phone-related connectors if you don't need phone integration (this also helped to reduce some of the clutter behind the head unit). With some finesse and utilizing a small precision screw driver you can simply push out any pins and relocate them.

Thanks for this great write up. I am doing this soon and it sure is a big help. I have a Bose system, so I am a big concerned about getting the correct harness. Why do more work? I see one on Ebay right now http://www.ebay.com/itm/110951854595?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649 , but I think I will call Kufatec or Enfig to see if they have one. Not sure if I will use my shark fin yet, but think I will just try the other antenna first. Thanks again and if anyone has some updated advice that would be great.

Thanks for the writeup! I installed my RNSE a long time ago based on your writeup and it all went in easy.
Really want to thank you for the time you put into the writeup. It's so invaluable for this kind of thing.

The only thing I can't change is the audio level when you start the car. It always defaults to a fairly loud volume.
Tried to go into the hidden RNSE menu but it doesn't stick.

FWIW here are some tips to get into the RNSE hidden menus

04 b6 s4 avant
acquired unit from a b7 s4 friend without auz or pin numbers
car came with a symphony 2, working sat radio and bose

I tried giving the head unit to a buddy who works at the dealer. The bottom line is to get the 4 digit unlock code you NEED the auz number. This is 14 digits I believe. On many units this is written on the unit itself. In my case it was not. As a note I found this later on in the spare tire bay. It was on a little sticker a few inches from the satellite radio box stickers with that box's xm number or whatever its ID number is called. Anyway, the way i found it is using ross tech/VCDS or whatever you call it. Anyway I went into the "radio" module and was able to find in in there under "advanced id". It's just the one that starts with "AUZ". Anyway, I took that number and sent it to these guys


and they got back with me in maybe 2 hours and gave me the correct pin. It all powered up and everything using that pin and everything from the OP's write up. random side note: I put the GPS antenna in the glove box. After powering it up and everything I got an error from the head unit when i tried to tune the sxm "this vehicle is equipped for a simplified installation of satellite radio...." anyway at this point I had my sxm working perfectly with the old head unit but i got this error using the RNS-E unit. It played the last station I was on and everything... just happened to be "xl hip hop" hood rat shit I know right? At least it was a good sxm station to be stuck on right? Anyway, I obviously wanted to be able to listen to other pimpin tunes on the BPM station so anyway i pulled the receiver box out of the donor car and it all worked great. I guess the issue was my early early early b6 sat radio box (this is located in the trunk) had too old firmware or something.

Anyway, the rest of the assembly was easy, the harness link is below that i used. The wrest of the write up was excellent. Good job to OP
