I'm not sure what you mean (upgrade an existing B&O or there is no B&O now).

I asked , at the demo we had at the BeoWorld Struer visit (2007?), if it's possible to install the B&O afterwards if there is no B&O from start. The answer was no. It must be done when the car is made. I think he said the system needs an advanced calibration to sound good.

That is my understanding too. Even if there was some way to shoe-horn the B&O in I can't see you getting the full benefit. Unless the second-hand one comes from a written off car it is hard to see why anyone would be selling one as it would damage the interior of the car to remove it.

A4's with the Bang & Olufsen sound system have a different wiring loom as well, which makes it hard to install the system afterwards...

I would suggest if you want the B&O system to wait until you can get a used A4 with it.

Options always devalue the fastest in a car, so there is a good chance to find one somewhere with it for an ok price.

I have seen people offering the B&O systems for Audi on ebay, my guess is to keep away. It's probably fake or just the aluminum cover for the standard speakers. Which doesn't really bring you much.

My guess is they are taken from crashed cars.

Even if it were... imagine the install procedure.

Though if you're good with that sort of stuff... go for it.

Just makes sure it's legit. Oh and report back the install on here!

Thanks for the info guys.  Will hold out for a used a4 with the B&O option at a decent price point.  Thanks!

If you are to install it, please check out a an A4 with and one without it - there are a lot more speakers in the B&O setup, and the fittings (inside of mirror fastening point, dashboard (3 units I belive) etc...) are very different. You may need some new (expensive) interior panels, too. The doors should be fairly easy, but ripping out the dash isn't...

So I agree with your conclusion - go for a used A4 with the system pre-installed 😁
