Sound system option code 811 mean B&O?
Hi So few cars seem to even have HK here in the UK but a car I may travel to look at says code 811 high end sound system. I'm guessing B&O, is that right? If so, super rare option here and frankly I've been unimpressed with HK in a couple of R231's I've test driven so this might be a good one for me.
Thanks

Not sure what year you are looking at or if they want a premium price, but I had the unexpected pleasure of a serious sound system upgrade when I installed a CarPlay module in my 2015 SL400. The sound is now simply amazing with all the bass, treble, mid-range, etc. that you would normally expect from a high-end automobile. As I said in other posts, I can now clearly hear the rear speakers. I installed a Road Top CarPlay kit ($300 on Amazon) and got not only all the benefits of CarPlay, but also the built-in equalizer. The car sounds like I added an amp to the factory system.
