A6 2002 RNS-E Questions

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.
