2022 GLS 450
USB's not charging or connecting
First time Mercedes owner, driving a 2022 GLS 450. Just recently the USB connections in the front console stopped working, along with the one in the center console in the armrest. So I can no longer charge a phone or connect to carplay. I've looked at the x167 fuse diagram but can't make much sense of it. My best guess is, if it's actually a blown fuse, its the 'Cigar ligher, front 457' or 'USB charging socket 127.' Am I dead wrong here? When I look at the fuse panel under the hood, it doesn't look like there's a fuse where 127 should be and when I look at the panel in the trunk its a similar situation. I don't see a fuse where I believe 457 should be.
Any thoughts if this sounds like it could be a blown fuse? And am I searching for the correct fuse? Why would it appear those two fuses are not present in the panels. Thanks in advance.

The 2021 manual mentions a fuse box in the cockpit and passeneger footwell. It's pretty vague on where they are though.

The fuse box is on the side of the dashboard under a cover.

From what I can gather, the USB ports are powered by the MBUX and not on a fuse (I confirmed the lack of fuses in our MY24). Are you still under warranty? I have read that the fix may be a SW update or hardware replacement.

GLS450 Fuse Box
I did take it out and take pictures of it, but while they look clear on the phone screen, zooming in, not so much...

Will_Atl is correct - it’s the fuse box in rear. My 12 volt went out and that is where the fuse was located. The dealer replaced my fuse in my 2022 GLS. Hope the USB-C fuse is located same fuse box.
