I did few a4 installs but yesterday I worked on A6 and need some confirmation from someone who did it before...

Car is 2001 A6 with Bose (Symphony I). I installed NAV and recoded VAG.
I connected V-Signal from cluster (blue connector) which probably wasn't necessary.

NAV is working but no GALA is retrieved so I guess I need to connect gray connector (CAN_H & CAN-L) with CAN on RNS-E.

Now ....do I need to keep V-signal once CANs are connected? One of install DIYs says that for Symphony I CANs need to be connected but there is nothing about V-signal.

just want to confirm before I go back to this install,
thanks for any advice ;)

All A6 C5 need the v-wire connected to the instrument cluster. In the A6, CAN-high/-low are only used for the other signals and communication back to the DIS.

Actually, since this is a 2001 A6 C5 (like mine), the GALA signal is available in the connector going to the Symphony I radio. I forget the exact pin, but it is listed on the Symphony I connector label. So with the correct adapter you have the GALA signal. My adapter was missing the wire, and I had to have the vendor send me a loose wire to install in the adapter.

You do have to run the two CAN wires to the cluster.

Incidently, I think I sent you a PM some month ago with a correction to your great list of install differences between the different models. Namely, 2000/2001 A6 C5 have the GALA wire, but you have to pick up the CAN signals from the cluster. Different from 2002+ models.

ok ....I wired CANs but looks like V-signal wire can't be connected in the same time. It locks NAV if it's connected. While disconnected it works perfect :wink:

One more thing tho...can anyone confirm working multifunction steering wheel in 2001 A6? For some reason I can't adjust volume from steering wheel.

The multifunction steering wheel controls do not work on the 2001 A6 after installing the RNS-E. The reason is that the steering wheel controller does not speak CAN, it uses CLK/DATA to communicate to the Symphony I.

You can install a controller from a 2002+ A6 and do some simple rewiring of the CAN connections to make it work. I looked into it quite a while back, when I installed the RNS-E, but I was not able to source the controller 4B0 907 487 F at the time. Now I have not had the time to get back to it.

I have both CAN and V-signal hooked up, and it works perfectly. Are you connecting the V-signal to the GALA in the old Symphony I connector ?

Alex,
if you only read my lengthy post for the C5 community....you'd have these answers. :lol: :lol: Have you tried the search function before?? :lol: :lol: :lol:

I 100% agree with Bjarne. I am actually looking more closely at my plug/play adaptor (non-bose, w/CD changer; with Telephone) from Lanny to make sure the wiring for GALA and CAN H/L (via 20 pin connector) are in the right place. I anticipate that I'll need to modify the plug/play harness a bit as I have a 2001 A6. Probably just 1-3 wires...no biggie.
