Default Satellite radio install difficulty?

I found alot of used Sirius satellite receivers for my 07 Q7 on ebay.

This one in particular: https://www.ebay.com/itm/26538197688...emis&media=SMS has the wiring connected but snipped. How difficult is it to patch into the stock wiring or would that even work? Would I need a new wiring harness that has the satellite connections or does the stock harness in the trunk already have the satellite connection cables? Do I need a new antenna as well? I guess my main question, is it feasible to install a used satellite receiver into a Q7 that didn't come with satellite?

Ok, so I signed up for a trial of sirius with my vin and apparently the car must have a receiver since the email they sent me has the receiver ID #. I guess tomorrow I'll look in the spare compartment and see if there is indeed one in there.

But in the meantime here is a section from my 1st Hex-V2 scan, could this be the reason it says no satellite radio installed?

Ok I went in spare tire well, don't see a silver box for satellite. Can anyone tell me where it would be located based on the following pictures?

I do not remember where the NAV unit is located at, maybe the left side of the trunk?

Anyway, my Sirius satellite unit failed early in the ownership. Since we do not need it, I bypassed it with a fiber optic loop ($~25). That Delphi radio is a PoS, breaking the MOST bus circular loop and cut off the audio. And yes the MOST bus sucks too.

You and I both have a 07 3.6L Premium. Therefore you should have the unit too. That radio, from what I read, is very unreliable. The ones you saw on eBay may be bad more often than not, so be careful when buying. My unit was on the right side of the car by the tailgate, behind the trunk liner. The Bose high def amplifier was there too.

I found the nav dvd on the right side of the spare tire. A video on YouTube shows how to take apart the hatch trim, and if there is a satellite receiver it is inside the right rear hatch trim. So when i get the time to take the hatch apart ill look. I would really like sat radio since i can't use my phone to play music via Bluetooth. Unless I get one of those expensive new dash units or the Dension unit from enfig. I agree the radio isn't the best, but it's a 2007 and it can be improved at the very least. I do like the in dash cd changer which sounds pretty good with the bose stereo. I just don't want to go back to burning .mp3 cds again.

I guess I'm not proficient enough in stereo electronics to understand the bypass. But if I do indeed have satellite ill buy a unit and activate it.

The fiber-optic 'test-loop' is a simple circular looking bit of plastic frame mated up to a fiber optic cable that creates a 'loop' right back to the connector...think ping-pong paddle, but smaller; that's the shape of it. You plug it into the car's harness/fiber-optic cable connection where it meets the component you want to either test for fault, or bypass to allow the signal to continue on through the rest of the interconnected MOST bits in the car. You can buy sets of fiber optic loops on Amazon cheaply...like $10-15 range. Most sets come with the male/female standard, fiber-optic connectors, so one of them will fit up to the car's fiber-optic harness, etc. If you buy a single loop, you've got a 50/50 chance you bought the wrong connector type.

Originally, the tire kit had a test loop incorporated, which looks a bit like a useless, broken child's toy part. One of my used car's had a test loop in the tire kit, the other did not. I've lost track of mine, as when I first ran across it, I didn't know what it was or why it was stored back there with the tire kit. It's just a very basic test tool that can serve as a permanent bypass, if need be, but you need to have one (or more) to troubleshoot the MOST connected systems on the Q7.

Is the Sirius box either of the circled items? I see undone wiring that matches what I have seen plugged into the back of the Sirius boxes on ebay. It also appears that there might be a fiber optic loop as mentioned above in the yellow wire under the blue circle. Any help appreciated.
