I have the 21U dashcam on my 2021 GLS450. (Posting here because there's more activity here than on GLS forum). I plugged a 256 GB thumb drive into the USB port behind cup holders. Told vehicle to record loop videos. It recorded mp4 files onto the thumb drive, but when I go to play the files on my phone, PC or other device, the file won't play. On the PC, the message is:

Can't play
This file isn't playable. That might be because the file type is unsupported, the file extension is incorrect, or the file is corrupt.
0xc00d36c4

I also can't find a way to play the file in MBUX and don't know if that's even supported. Has anyone been able to record and play dashcam videos on any device? Any help is appreciated.

 

Did you try VLC player? Could be a codec issue, MP4's generally play better on Apple devices.

 

That works! Thank you!!! I really appreciate your help.

 

I had to use VLC on my MacBook as Quicktime display was black.

 

VLC Works great on Windows 10. Thank you for the solution!!

 

Wish I were dealing with the problem since dashcam was not available on my 21 GLE, nor can it be retrofitted/activated.

VLC plays anything on PC or Mac and that's the way to go on either platform.

 

It’s only 720 resolution, no audio capture and manual start every time I start the car. Still hoping MB has a future automatic start update in the future. It’s my first dashcam so I really didn’t know to ask the right questions at the dealer. Not a whole lot of specs were shared at the dealer other than very basic info.

Will be more prepared for my next purchase, so just another learning experience!

 

It seems it will be possible to activate it at some point (assuming you already have the U19 Augmented Reality feature/camera, then the Dashcam is just a software activation). There's another thread about it here, there's now a "Buy" option for the Dashcam in the Mercedes Me app but it's not yet working.

If you don't have AR, I noticed on https://rjautomotive.net/products/au...amera-retrofit that you can retrofit the AR camera (assuming you have MBUX High), so presumably you could enable the Dashcam in that case as well?

 

Can open the files in VLC for Mac but viewer shows no content

 

What version of Mac OS are you using?

Mine works with VLC and IINA and QuickTime Player. The files are saved as Mp4. It even has a preview image in a Finder window.

 

I'm totally stumped by this one. Tried two different Macs and I'll try a third a bit later. Tried everything except Adobe Media Encoder to see if it can open and transcode. Particularly frustrating since I am a video professional.

 

Files won't even play in vehicle. I can get the thumbnail but it only displays blank video. Next step is to try different recording media. I'm using a Samsiung T7 1 tb SSD formatted ExFat. Will now try an SD card with reader.

 

Well.... tried a USB reader with a simple 64gb SD card and worked. Could play video in vehicle and VLC played on all the in-house Macs. It somehow didn't like my Samsung T7 SSD.

 

I us a 256GB card formatted as Fat32. Maybe the Mercedes system doesn't play nice with ExFat
