Hi rlumsd,
We stock all the Mercedes radios for sale or exchange. I would suggest that you exchange your 780 for one of our rebuilds. We replace far more components than the factory is willing and it comes with a 1 year warranty. Let me know if you want to do that. The BE780 units are currently in stock and ready to ship. Hope you had a great Christmas. Talk to you soon.
