During your reboots did you have any response from the unit at all prior? My unit is totally unresponsive, as in blank screen, no reverse cam and flashing power button. How long was before the unit became responsive after holding the power button ? Holding the button longer than anything over 30 seconds seem moot at this point haha.

Hi All-
Recently the Command / Computer / Radio in my wife's 2014 E350 started randomly rebooting or failing to come on at all. It happened while I was out of town, so of course, she took it to the dealer and spent $200 for them to say "We tried everything and you need a new system at a cost of $4,400."
Googling around, I've seen several videos and articles that describe using a fiber loop adapter to systematically "remove" various components or modules from the MOST Network; modules like the Sirrus receiver, nav unit, voice control module, etc. In THIS video the fellow uses a fiber loop adapter to "remove" the potentially failed module from the MOST Network, but in THIS video, the guy simply unplugs it.
The modules that I have heard of people having success "removing" from the network are; the CD changer, the amplifier, the Voice Control Module, the satellite radio receiver. I'd have to believe there may be others. I've also read that of these modules, with the amplifier, that module must be replaced, you can't just remove that one from the MOST network.
Is there any definitive guide, or video or Wiki or anything regarding this issue, troubleshooting procedures, and fixes? I really can't afford to replace this thing at $4,400 and my wife can't survive her commute without a radio. Kind of a bummer that her 2014 vehicle with <100k miles has this expensive and problematic of an issue. Hopefully I can resolve it.
Thanks,
Chris

My 2016 E250 command system went into a re-boot loop: it would come on as if powering up, operate correctly for a few seconds then reboot, over and over continually. Tried disconnecting both batteries for a few hours to no avail;. Took it to the dealer who said they couldn't get it to stop rebooting and gave me a $4k+ estimate. I removed the radio and it sat for weeks while I researched electronioc repair companies where it might be repaired for $2500. Finally, after mostly getting over sticker shock, resolved to let the dealer repair it.
Made an appointment and re-installed the radio just so the dealer wouldn't give me a hard time, and discovered that it now worked as new. No need to take it to the dealer, just pull it and let it sit for a period of time. It is an easy removal....

Your NTG was in a severe boot-loop, rebooting the car itself didn't not help NTG.
After pulling the unit out for some time and reinstalling it, now it works well.
This is good karma! I am guessing your unit needed a sort of vacation... likely a marginal 16Volts capacitor gone bad in a hurry working under 14.9V + ripples.
This Mitsubishi head unit internals remains a mystery to me, safely hidden behind countless screws
Repairs between $2500 and $4000 are a good encouragement to spend a couple hours to fix the built-in defect.

Capacitor discharge, or some "BIOS setting back to default".
The boot loop, as far as I understand, is the Windows CE/XX failing to boot. Similar to Windows 10 boot loop I guess

I am still trying to figure out the intermittent rebooting problem. Can you expand on your reply? Im an old electronics tech so you can speak electronic to me.
Thanks

the fundamental issue is, they used filter capacitors specified for 16V on a system that can run as high as 14.9V and has ripples on top of that. take the units apart, find the 16V electrolytics, and replace them with quality 24V electrolytics of the same microfarad values, and boom, it should work for life.

right now, keep in mindthe failed power supply caps is is only an assumption (not proven solid).
There is an engineered failure in that Mitsubishi unit that materialize regularly. It's Not a random one in a million type of failure...
Based on what we've seen on this chassis we can make educated guesses until we find proofs.
It could be the amazin' 16V caps,
could be oxidized solderless pins,
could be poor painted GND,
could be failed boot enumerations,
....
Without any clue, a schematic or troubleshooting procedure, we are helplessly trying to repair this $4000 rat-trap.
I know very little about this mystery-box. Mine boots and plays sound surprisingly much faster since I have resoldered my CAN-B modules.
So I can confirm that CAN plays a role in NTG boot speed.
Perhaps there's a timeout that causes unit to boot-loop searching for peripherals. I have not dealt at all with the MOST fiber ring. I think MOST is fine even though we know there is an enumeration of fiber devices.

Our incentive is we can expect a simple repair once it's all figured out.

I too suspected and eliminated 'painted GND' by installing a separate ground, then cleaned all the external connectors, wiggled wires and connectors, tapped and thunked the chassis, scraped a plastic tool over solder joints, looked for hot spots and cold solder joints with a magnifier, and could not get the unit to fail. On the next drive I stopped to refuel, and upon re-starting ntg went into reboot. Capacitors are high on my suspect list due to the recurring problem going away after sitting.
