My COMMAND system has been acting up lately. When I start the car, the Mercedes LOGO comes on for a few seconds and then restarts. It gets stuck in this loop. If I keep hitting the Radio ON button over and over again really fast, it finally boots up and works normally.
I believe I have an issue with MOST ring. Seems like one of the components (Amplifier, Navigation, Radio etc.). I want to troubleshoot the MOST ring by individually connecting a fiber optic loop/bypass to each component one by one to find out which one of them is failing. I'm trying to identify the correct bypass loop and need some help.
Where to purchase fiber optic bypass for Mercedes W221

this is also referenced on the you tube video details.
I know the YouTube guy is selling them. I just don't know who to believe.. the YouTube guy or all the eBay sellers who are selling a different version. Has anyone tried either on a 2007 W221?
