Greeting guys. I recently purchased a 05' E500 wagon. It is amazing to drive. Well unfortunately, it does not comes with the HK logic 7 sound system. I know there is bunch of aftermarket options I can pick, but I rather go with "factory options". So, I an wondering if I can swap the HK sound system in with my vehicle? If so, does it requires any trim or reprogram?

Best regards,
