did you end up figuring this out?

Just Google search BMW MOST loop and you'll see them pop up. Unless you're on about the android system we installed for our customer which is from a company called andream.

Sorry should of made it abit clearer the loop connector. Found them. My problem is sound cutting off also when I'm in the android mode my idrive controller works but when back in normal bmw mode there's no movement on screen but I no it works though do you think this fix could resolve this?

@@1hairyhaggis hi Gary, yes it's very likely that one of the other modules linked to the idrive system is causing it to freeze and sound cut off. If Bluetooth is fitted to the car as standard I have found that 99 percent of the time it is that module (as per the video) that causes the issue. If you dint have Bluetooth fitted as standard then it could be another model on the network.

@@ultimatedrivingmachine4004 thanks for getting bk to me so quick. I pretty sure it came with it standard 🤔 I will buy n try the loop and see how I go from there.

@@ultimatedrivingmachine4004 hi there received my most loop found my bluetooth module and hey presto it works now so faulty bluetooth module

Same, have you managed to find a solution?

​@Rousr I have a similar issue. I had to take out my glove box on my E60 to replace my blower motor and resistor. During reassembly, I noticed my MOST port in the glove box compartment had the output cable (red light) hanging out of the harness. I reharnessed it and placed it back within its mount, and closed the little compartment. I got static, skips, and even the dreaded SOS error and aux input muting. So I took it out, and tried again. It worked ok until I started driving. So I took it out of the compartment completely, and let the wire hang. It's been sounding good until I replace the cable with one on EBay. At least it's in a place that's readily available. I believe I somehow damaged the glass or got it dirty so the information being sent through the light is faulty. I'm expecting a new head unit in the mail anyway, so I'll swap the cables out during the install.

Glad it helped :) To be honest it doesn't matter which com port it is set to. As long as you make sure they all match up. Glad you're sorted

Uaually if the MAK or the CCC unit is faulty, it wont boot at all. Usually it shows the BMW logo and never gets past it. In which case the MASK unit is faulty. A break in the MOST bus from another module usually allows it to boot up fully for about 30 seconds before rebooting. Hope this helps

Hi Sir thank you for your response. Really appreciate that! I would like you to advice more on my car unit problems which I can not identify clearly: 1- My car sound is some time is smooth but sometime it is flashing and cut off. 2- The Mask Unit (In my case, CD Changer (e60)), it can run for a while and still keep rebooting more often. Can you advice whether the problems are from Fiber Optics or Mask Unit?

@@automartkm If it is running for a while and then cutting off.... it is liekely to be one tof the componants on the MOST network. You can test for this by unplugging them one by one until full functionality returns... For example. try unplugging the CD changer, if it still has the same problem, plug the CD changer back in and move onto another compopnant, for example, the MULF (bluetooth) module. Worst case scenario is that the CCC/MASK unit is possibly overheating.
