Perfect Fit. What a gem!
Perfect fit for my 2008 Mercedes E350 (w211). DVD Nav was not working and later determined to be the cause of a battery drain (car will go dead after 3 days without driving). However, by unplugging the Nav, the radio will not work. Now with this Fiberoptic loop, I can just attach the loop and disconnect the Nav altogether. Radio works and no more battery drain. Lifesaver!

Works well
Worked to bypass the SOS module and get my radio working again on a 2005 w211 e320 cdi. Also works to diagnose bad modules in the fiber optic network one at a time.

Good quality worked as advertised
A must have for any DYI Benz owner with the D2B Audio system! If your radio goes out, any one of 4 to 8 comments (depending on your factory options) is most likely the cause, and you could go nuts (and Broke) replacing one at a time or just use these to bypass one component at a time ๐. Just check to make sure if you order the two adapter package (1 male & 1 female) you get what you order first time I received 2 males . The issue was resolved but it did cost me time in the diagnostic stage.

Great loop, double check compatibility
My vehicle was listed as compatible however the plugs were an entirely different shape. With some modifications however I was able to make the MOST loop work and properly bypass the failed module.
