DISCLAIMER: This is to serve as information ONLY. Follow this at your own RISK!

If you have an Audi A6 Symphony II BOSE and want to upgrade to RNS-E, then YOU MUST DOUBLE CHECK YOUR RNS-E CONNECTOR.

Go to www.nsxjr.com and read their installation instructions to get a good idea of what to do. They have a lot of good pictures and pointers.

I just installed my RNS-E in my 2002 A6 Symphony II BOSE and I got a CHECK ENGINE LIGHT after driving for 10 minutes. I took my VAG-COM and read the fault code â€œSpeed Signal Implausible.â€ The RNS-E plug and play harness had a wire connected from RNS-E connector B pin 3 to connector III pin 1, which is correct for Symphony I systems. For Symphony II BOSE systems, the RNS-E connector B pin 3 should go to your GALA wire (back of the instrument cluster, blue connector, white wire with blue stripe) directly and not to connector III pin 1.

Another wire that you should watch for is the alarm wire. My RNS-E connector did not have a connection in connector D pin 14. You should have a wire from connector D pin 14 to connector III pin 2 (without this wire, your RNS-E will still function).

The use of the alarm ground:
â€œ1) The RNS does a hard power off when you lock the doors with the remote. The hard power off turns off your CD changer and BOSE amp immediately. Without this, the RNS will wait an hour to do the hard power off because it does not know when you have locked the doors.
2) The RNS starts to boot up (come out of the hard power off) as soon as you open the door. This means that by the time you actually start your car, the RNS is probably already booted up and ready to go in standby mode (by doing this, it initializes the GPS system, reads the songs on your MP3 card, etc).â€ (Thanks NSXJR)

Another wiring difference between Symphony I and Symphony II is the Bose ground wire (connector B pin 7 to connector III pin 1)

The CDC chassis ground from connector I pin 10 should connect to ground in a convenient location.

Glad you got everything working.

Also, the Symphony II to RNS-E PNP harness connection chart is now available on the downloads page on my website.

I would just like to add that your description of the Alarm GND wire connection is absolutely correct for the Symphony II. However, for owners with the Symphony I, your Alarm GND wire is the big brown single pin connector instead of what is described by MAD.

Nice summary, the first time someone explained what that alarm wire actually does :lol:

Lee, would it be much work to show the actual connectors with pin numbers in your diagram? The chart is very handy but it would help to show which pin in the Symphony connector is which number. Just an idea to make it even easier for others to check their adapter...

I have updated the Symphony II pdf chart to include pictures on the second page. MAD also sent me some good pictures specific to this post that he will hopefully attach to this thread as well.

Looks like someone had to be the "guinea pig" on this one. Sorry man.

I'll be updating my pix as well with detailed pix of all the locations of these connections etc. I'll have a Sym I-to-RNSE and a Sym II-to-RNSE version.

I don't know if the plug/play adaptors will correct all these connections...but I have been "tweaking" these harnesses for a few of you (upon request of other customized wiring projects). The big issue being: Alarm ground, bose pin and reverse wire.

NSX jr did all the original discovery in this area. I still need to tweak my own harness in my 2001 to correct the alarm ground and add the reverse wire.

Stay tuned.
