Firstly thankyou to everyone who has posted such informative information and advice on the site, it is a great reference.

I am installing an RSN-E in a 2002 A6, no Bose, No Telephone, No CD, from a Symphony II install.

I have numerous printouts of the various installs and appropriate posts, the pin-outs Sympony II and the RSN-E. I have two harnesses, one a suposedly genuine Kufatec the other of "unknown" 0rigin.

Was thinking I would have a simple install, but neither connector seems correct so thought I would ask a couple of things before I get the car in bits !

The Kufatec unit seems for a Bose installation as no speaker connections Brown plug or RNS-E "A" connections and the Bose wire from connector B7 to ground. The other harness has the speaker connections but has no RNS-E connector B at all, which seems a bit strange.

The questions please:

1. The GALA signal has to go to what pin on the RSN-E ? (is it pin 3 V-signal connector B ?) In Radef's install it went to pin 1 on the "8 pin connector 3" plug, but then neither harness has this connector wired through (eg pin 1 connector 3 to the RSN-E pin 3 connector B)

2. The K-line (pin 7 connector 3), should that go to the RNS-e pin 5 connector B ?

3. Are the harnesses the same for A4 and A6 installs so if I could correctly cable the Kufatec unit with speaker connections and remove the Bose link the it should work ?

4. The GPS does not have a Fakra connector, the brass plug it has seems like it will fit (tight), will this work ?

Any advice would be appreciated.

Excellent research from your side so far.

1. The GALA signal has to go to what pin on the RSN-E ? (is it pin 3 V-signal connector B ?) In Radef's install it went to pin 1 on the "8 pin connector 3" plug, but then neither harness has this connector wired through (eg pin 1 connector 3 to the RSN-E pin 3 connector B)

Correct, pin 3 in connector B on the RNS-E should get the GALA/speed signal

2. The K-line (pin 7 connector 3), should that go to the RNS-e pin 5 connector B ?

Correct too.

3. Are the harnesses the same for A4 and A6 installs so if I could correctly cable the Kufatec unit with speaker connections and remove the Bose link the it should work ?

They should be the same except for the speed wire which would be missing in the A4 adapter. Moving the speaker connector over to the other adapter and removing the Bose wire should do the job.

4. The GPS does not have a Fakra connector, the brass plug it has seems like it will fit (tight), will this work ?

The connector you are talking about is SMB (used on the older RNS-E and Symphony I). It will fit but it doesn't lock and may fall off eventually. But the antenna should work, I have seen two cars so far which had an SMB GPS antenna connected to the RNS-E and it was fine.

Good luck...

Thanks for the prompt reply.

Do the correct harnesses map Connector 3 pin 1 to Pin 3 Connector B ?

A new connector seems the easiest solution rather than chasing around finding odd pins.

Just a point of curiosity:

On the Symphony II, Connector 3 pin 1 seems to be originally the Bose connector, any idea why this connector is not generally retained and connected through to Pin 7 Connector B (Bose pin) and let the original wiring take care of this rather than being connected to ground for a Bose install ?

In which case rather than using connector 3 pin 1 for the GALA, any spare connector could be used and connected through to pin 3 connector B for the GALA

Thanks again !

I have seen several adapters, some had the Bose wire between the correct pins in the Symphony II and RNS-E plugs, some simply split the gnd on the RNS-E side for the Bose pin. Maybe it's cheaper because they need one pin less? I don't know.
