## Questions & Answers

**Q: Is this work for mercedes benz s550 2008?**
A: Hello,
The fiber optics loops should fit, could be a little complicated to get it ready to install. As long as the system you are working on is fiber optic then yes. If a wired system then no it won’t.

### ⭐⭐⭐⭐⭐ Review
*by P***E on 13 May 2025*

After a week of rain my 06 Audi A6 MMI just quit. Dead. Zippo. Checked all fuses, they were all OK. Held down reset buttons, nothing. Complete PC boards were available on Ebay but the entire center console needed to be yanked out , OY!! I was almost ready to take the car to the dealer but @ $235 an hour though that there must be another answer. Reading posts I discovered that the MMI modules are linked together with optical cables and if one of the modules (there are a few) craps out, nothing will work. So I ordered this, and it came the next day. The first module I worked on was the Satellite Radio module. I easily removed the optical cable from the module, snapped one of these connector cables in it's place, and the other optical cable on the end I removed from the Satellite Radio module. Lo and behold the MMI instantly came back on line and is working fine.
