after dealing with audio cutting in and out for over a year, this simple quick installation brought my audio back. dont hesitate to try it before you start replacing modules

Exactly what I needed for my 7 series! I bought two just to have an extra one around, turned out 2 of the3 modules were bad so I needed both. I have my radio and chimes back!

1. I was able to use this to diagnose a problem fault in the radio system on a 2007 BMW 335i. Using this I was able to isolate the failed component (XM Radio module). 2. This is now used as a permanent bypass as I have no current intention to replace the XM module.
