-2011 c300 luxury with factory fiber optic harman kardon sound system

I purchased a pioneer radio and I’m having a hard time finding the correct adapter for a good price in order to retain the factory amp and fiber optic wiring. My question is is there another option for a better price than this?

this is the one I found and all the others I’ve found are for other models or earlier years. And it’s way too expensive 🤔

any advice is greatly appreciated 👍🏽

Did you get this figured out? I know this post is old but I am losing my mind trying to replace the head unit in my 2008 C300 4matic sport. It is equipped with HK fiber optic wiring and amp.
