Hi all, thanks for reading my post! As the title says, I'm new to the Audi world after converting from the world of diesel trucks. I have a 2006 A6 3.2 without nav or factory satellite. I located and purchased a used Sirius tuner PN 4E0 035 593. There is also a number SW: 4E0 910 593 B. Is this the correct unit?

I see where the unit is to be installed on the rack in the truck. I located and connected the wiring harnesses to the unit (1-black connector, 1-brown and 1-green connector). Is the 4th connector (2-pin) to remain unused? There was an additional connector with what appeared to be a loop connected to it.

Thanks everyone for your input, and go easy on me, I'm new!

UPDATE: Disregard - I figured it out. I see that the loop has to be disconnected and that connector needs to be then connected to the Sirius unit.

 

I hope you have the shark fin antenna on the roof. Since the car came without the nav and satellite radio it may not have the antenna and that is not an easy aftermarket installation.
