2021 E450 Dash Cam - Automatic Recording ?
Per the dealer, the automatic start option is illegal. This is odd for 2 reasons: First, I've seen Youtube video's in which the automatic start is on a menu selection (the video might have been made in the UK because the narrator has a British accent)....and second, every aftermarket dashcam I've seen has the automatic start feature.
Does anyone have any information about this? Is it only illegal in some states, but MB has therefore eliminated this as a possibility for all states? Is it a possible future upgrade?








4/25/21 UPDATE:
Car goes in May 3rd for a week(?) for them to diagnose the dash cam problem. I'm going to push to get my $200 back if they can't fix the problem, and get it to start recording when the ignition is turned on... We'll see, will update.

Car was at the dealer for a week and one day, they have no idea what the problem is. Maybe next week I will go back and begin hitting on the GM and push for a refund, it will be fun if not fruitless. I have not been using the MB adapter (ever). I have been using the same USB-C adapter I got from Amazon, maybe I'll try another connection. I did learn that the MB USA said the option to have the Dash Cam activated each time you start the car is not going to happen in the US. They did a "factory reset" that only made me reset everything. I'll muck around with it with different connectors, I already tried different thumb drives, some with recordings and some without, nada! Thanks for the input, I'll let you know if I find anything...
P.S. the Amazon adapter is the same I was using when the dashcam was working??
Below is a link for the one that worked for me. It does not use an adapter it plugs directly into the USB-C plug. I am using the connection closest to the dash by the cup holders.
As far as the auto-record option goes I insisted until I got a member from "Executive Referral Management team" to research the issue and call me. The auto record option is not active because it's a new factory feature being installed by manufacturers and for some reason, the NHTSA has not approved that feature. We know how silly this sounds when you can buy a $20 dashcam and it auto records but that was Mercedes-Benz story. The software is already installed otherwise it would not be in the built-in instruction manual see https://i.imgur.com/84xGLHY.png. The feature should work as advertised BEFORE the purchase. Selling a Dash Cam that does not auto record is like selling a car clock you have to set the time every time you turn on the car. If any features are disabled it should be noted on the sticker. The manual should also state that the feature may not be available in all countries. Nowhere in any MB documentation is this stated.
The representative agreed that lack of disclosure is wrong but fell short of any solution. That is why we need to keep up the pressure. It was the deciding factor between the two GLE450 models I had to pick from and it was a lot more than 200 dollars difference.

Mercedes-Benz has dropped the ball on this one. A good friend of mine is a state trooper in FL. They have dashcam's that record 360's with sound up to 35 ft away and do not obtain permission from anyone to record.

Just ordered the "sub C" drive, who can't use another thumb drive? I think I'll start making calls about the dashcam option to MB USA and push the auto-on option. However, I'll probably wait 'til I get my dashcam working again. Going back to the dealer if the new drive doesn't fix the problem. I'll keep all informed.
The Best of Mercedes & AMG
PROBLEM
- Mercedes-Benz sells and you probably purchase a factory-installed dashcam that will not Auto record. For the purpose of this post, we will only talk about vehicles purchased and operated inside the USA.
- There is no Mercedes-Benz notification on the window sticker or manual about the factory disabling automatic video recording.
- Furthermore, the onboard electronic manual shows how to activate the feature hence there is no way for you to know this feature is disabled before purchasing the vehicle.
- The missing auto-record feature is analogous to having a clock in the car that needs to have the time set every time you start the engine. Not what you would expect from a world-renowned "The best or nothing," automobile manufacturer.
- The dealer and Mercedes-Benz will attempt to convince you without any evidence that it's illegal for them to activate the auto recorder. This is not true. The dash camera does not record audio or video inside the passenger compartment. The aforementioned recording would be illegal in some states (CA surprised?).
- The Auto-record feature is not working because Mercedes-Benz has not aggressively pursued approval from the NHTSA. Approval is needed because it's a new feature.
- Here is one of many articles on the legality of dashcam recordings. https://www.azuga.com/blog/dashcam-l...ers-and-owners
- Vehicles with the Dashcam 2U1 package are supplied with a "Media Interface adapter cable" but no USB flash drive.
Workaround - You can register the dashcam to 'Favorite' on the center console (the button with a star symbol). Once done, it needs only two clicks without even touching the screen (you need to move the dashcam icon to the leftmost position so you don't need to scroll to the right). Keep in mind this will not resolve the disabled auto-recording feature but gives you a workaround albeit a lot of discipline required to remember to turn it on.
- Once you plug in a USB Flash Drive using the Mercedes-Benz supplied adapter the manual recording may or may not work. In most cases, it works for a while and then stops, becomes intermittent and eventually, the DashCam software in the Mercedes apps disappears. Don't waste your time with the dealer they do not know how to fix the issue. They will factory reset your MBUX software, you will lose all your settings and it will not fix the issue.
- Regardless if you use the workaround or not you might get the following error.
Function Unavailable -
FIX - The fix consists of installing a newer USB Type C aka "sub C" without any adapter. Once you start the engine within a minute the software will appear in your Mercedes apps and you can manually initiate recordings. The wait time will have to be repeated on each use. Here is a photo of the one that worked for me.

- Complain to Mercedes-Benz in writing using this email address. mercedes_benz@mailac.custhelp.com
- When you received the canned response "Thank you for your email to Mercedes-Benz USA. However, we regret to inform you, the vehicle is designed to require manual activation of the dashcam within the US market, etc..." do not accept that as an answer. Request that they raise your request to the level to someone that can authorize enabling the option that was disabled without your knowledge or consent. This will result in a phone call (they don't want it writing) from the Executive Referral Management team. Explain to them your displeasure and frustration. They do not have an answer for "Why was this not disclosed before the purchase?". See if they will send you in writing what efforts have been undertaken to get approval from whatever agency is holding them. If we can get the department number and address we could flood them with letters.
- The more of us complaining the greater the chance of the issue getting fixed as these guys have access to the engineering and legal teams.
- the software is already written to provide the functionality. All they have to do is stop disabling the auto-record feature which can be done via an "over the air" software update.
- The problem you are experiencing was an undisclosed issue that would have changed your mind about the purchase.
- PLEASE Post any new revelations or updates to this thread.

I live in a country where automatic recording and loop storage are legal, but even using a native Type-c USB Storage device (Exfat), the recording function is working only from time to time.
Is like the camera is missing.
I did not get an adapter! My car is a Mercedes EQC.
I use a 512 Gb USB SanDisk Ultra Luxe Dual Drive. 512 GB, USB 3.1/USB Type-C, Metal




Now it seems to work and I believe that the previous USB drive was too heavy (all metal).
This weight created problems with USB-C contacts on potholes; this is my theory today.
I am not sure the spec of the MB dash cam but most dash cam brands (eg Viofo, Blackvue) have an upper limit of 128GB (some newer models can handle 256GB). So, your previous 512GB drive might create problem with the dash cam.




Don't know why, as there are few countries in Europe where a dashcam is illegal (only Luxembourg i think). Besides, all teslas have this feature...
Then again, if i have to start it manually, it's pretty useless. another problem is that the camera doesn't have a great image (from what I see when using augmented reality)

Per the dealer, the automatic start option is illegal. This is odd for 2 reasons: First, I've seen Youtube video's in which the automatic start is on a menu selection (the video might have been made in the UK because the narrator has a British accent)....and second, every aftermarket dashcam I've seen has the automatic start feature.
Does anyone have any information about this? Is it only illegal in some states, but MB has therefore eliminated this as a possibility for all states? Is it a possible future upgrade?
There is no legal reason I can find in the UK why this cannot be done, Tesla do it!




MBUX 2nd Gen in W223 and gen20x in W214, has this auto start feature. (totally not legal issue)
We may wait for the newer firmware to be resleased to see if it will be available or not, but very low chance.
If so I might try changing my country in the mercedes me app to your country and purchase the dashcam. Who knows, it might just auto record that way.
