First, let me start off by giving you guys my basic info:

I have a 2001 Audi a4 (b5)
I had the Symphony I w/ bose head unit before
I have an a6 RNS-e (4B0)

I've been following the NSXJR.com guide for installing the RNS-e. The install is pretty much finished. My GPS is working. The only thing I can't figure out is how to get the CAN signals! I followed the directions on getting the CAN signal from my cluster (my clock is digital so it has to be there, right?). I moved pins 12 and 13 on the grey connector to 5 and 6 and I've also rewired the connector that plugs into the RNS-e harness. After doing that my RNS-e doesnt light up and when I VAG the car I'm getting fault codes saying that the CAN signal cannot be found. I've already Vagged the RNS-e to fit my setup. Whats wrong with this??? I've included some pictures that might be able to help. Any help is appreciated.

This is a picture of the grey connector behind the instrument cluster




This is a picture of the green connector behind the cluster. I was thinking maybe these could possibly be the CAN wires?

I'm not sure that any instructions suggest moving the wires on the grey connecter, I think they are either in 5 and 6 or not, if they were already in 12 and 13 then you would just connect these wires to your RNS-E, moving them isn't going to help!

Whilst the wires on the green plug *look* the same colour as CAN wires I'm not sure if they are.

I have a 2000 S4 (B5) and my can wires were on 5 and 6.

If i was you I would move 12 and 13 back and just run a test set of new wires from 5 and 6 to the RNS-E connector.

These wires are just dumb wires they don't know if they are CAN wires or not, they are only CAN wires when they have CAN signals running through them...

Yes, by moving these wires you are re-using wires you dont need anymore for CANbus connections.

So, in the grey cluster plug you move pin 12 to pin 5 and pin 13 to pin 6. Looks like you have done this correctly.

In your 20-pin radio plug, you move pin 9 to pin 12 and then pin 8 to pin 7. By doing these two steps, you now have CAN H available in pin 7 and CAN L available in pin 12.

Of course, the last step is to make sure your RNS-E wiring harness is correct. It must connect the CAN H pin 7 to RNS-E pin D9 and the CAN L pin 12 to RNS-E pin D10.

Done this bit yet?

Using Ross-Tech VAG-COM, open ‘Controller 17 – Instruments’. Select ‘10 – Adaptation’ from the menu on the right of the open controller screen. Enter ‘062’ in the Channel setting and click the Read button, the setting will likely be 0 by default. Change the setting to 5, click Test, and verify that 5 appears in the Test area. Apply the changes. The RNS-E should now display track and navigation information in the instrument cluster

The only thing left to do is to verify you have everything wired correctly. If these instructions were followed properly, then it will work. I have done this same thing in 5 or 6 different cars and they all work fine. There's no magic to making this work. Either the wires are connected properly or they aren't

I followed Lee's guide and I have a 2001 B5 S4. I didn't try to swap wires I just ran new wires. I would try two things. First switch the wires you have (put the wire in pin6 in pin5 and vice-a-versa). If that doesn't work I would run new wires from the cluster pins 5 & 6 to the harness. As Lee said - we all know it works.

I'll try that after I cool down a bit. I'm fed up with this thing. Been working on this installation for 3 days! And it's too bad I broke the damn pin off of one of the connectors because now I have to fix that too :evil:

IT WORKS!!! I had to run new wires...

I still have some more questions though...

1) Do I have to run the GALA wire?
2) Should I code it as an a6 or a4 unit?

Thank you all for all of your help. I never could have done this without you guys.

I understand. Last night with limited time I installed a Bluetooth module - adding it to my existing RNS-E installation - and it wouldn't work. My RNS-E would power cycle with it connected and I was totally frustrated because I checked all the codings and they were correct. I couldn't even get my phone to see the BT module.

I thought about it overnight and figured the only thing that could be wrong was swapped CAN H/L wires at the BT harness in the trunk. Sure enough, this morning I switched the wires and it all worked.

All I can say is once you get it all properly set you'll be a happy camper.
