Most bus reset

Hi guys i need to know how to do a most bus reset..

Open your glove compartment, you'll see a trap door that reveals fuses, open that door then you'll see the MOST Bus ring, unplug that for about 30secs I believe and plug it back in and it should be reset.

What's the reset meant to do?

My cdc is giving no sound so going to see if the most bus reset cures it.Also is the ring near the fuses..

Its the thing attached to the trap door...

Can you post a picture of it. I thought that ring in there was to neutralize the transmission. I'll have to have another look in there to see what we are talking about

Nice buddy i found it..Much love..

I just found out why my audio, sos, bluetooth and beeps were not working on my e93 m3. I unplugged an optical ipod cable from my glove box a few weeks ago. all audio went out - 3 weeks of driving without phone, nav audio or radio was killing me.

Playing around in the car today i disconnected battery, hard reset on the MOST-Bus - no luck!!!

I found out that it stopped working because it was not grounded to the chassis properly.
Figured this out when the MOST-BUS box touched the metal part of the car near the fuse box in the glove compartment. all of a sudden i hear loud music and see a spark from the MOST-Bus box.

took it to Calabasas BMW 3 weeks ago, the service guy told me that since the car had done 53k, my warranty had expired and it would cost aprox. $1200-2000 to diagnose and fix.

Fixed it myself. - try to make sure it is grounded properly if you have the same issue.
