2026 e350 Built-in Dashcam: Input?
Hi All, My new e350 comes equipped with dashcam capability (for what appears to be a one-time fee of $200 to activate). If I understand this correctly (input please), it stores front-only dash cam footage on my own thumb drive. I've read to get a 1-TB drive, and weeks of data can be saved on it. Here are my questions: IF I active this feature, the purpose is to record any front-end collisions with a car, person, or whatever. For those who have this, is the quality good enough? Next, given that I haven't studied this part of the owner's manual, does it automatically record every time I drive, or do I have to manually turn it on every time I start the car? Any other considerations about its use, and pros/cons?
I've considered after-market dashcams which are undoubtedly more versatile and more clear. But they all seem to accompany unsightly wires, unsightly and/or large difficult mounts, continual recharging. I'd like to avoid those, IF the built in dashcam is adequate. Help! Input and direction would be great from those who use it or tried it.
IF it is a one-time charge of $200, seems like a small investment. Thanks!

It is a one time cost. The dashcam automatically starts when the ignition is turned on. There are so many settings and features that you must read the manual. For example it can automatically record if the vehicle is bumped. There is an optional rear camera for the system. The bottom line is that it is designed explicitly for the MB and is "built in" not appended with brackets and dangling wires.

OP: It's a good option. I've had it on both 214s i've had. For $200 and the cost of a USB-C drive (which i already had), it's nice. Turns on automatically when you start the car, rolls over the oldest recordings for space, and the camera quality is good. I only have 512GB and given the amount i drive it holds about 30 days worth of recordings. To me, the biggest bummer is that there is no rear camera because the rear cameras are tucked away when not in use.
Will a dedicated dash cam have more features? Yes. better image quality? Yes. Rear camera? probably. However, i didn't find the extra wiring and clutter or additional cost worth it.

Maybe I am missing something -- but if it's set to automatically start recording when the vehicle has been bumped, of if there is a collision -- isn't that too late?

There is an option to turn on the camera recording when you start the car. It keeps recording until you open the door to exit and the driver display is turned off. If you don't select the automatic turn-on, you can turn the camera on by tapping the camera icon in the top right of the screen. You can choose to overwrite recording when the drive is full or stop recording when the drive is full.
I have been pleased with the image quality.
I connected a crucial X10 Pro 2 TB SSD to the central console compartment USB-C port. It draws 0.45 W. I believe the USB-C port will be turned off 10 or 15 minutes after shutting off the car shutting off, but I haven't tested this. A high endurance SD card made for video cameras seems like it would cost less and be a nice option, but I haven't tried one.
It is a $200 one-time charge plus the cost of a USB drive. It links to the car as a "permanently active" digital extra.
Here are the Owner's Manual sections for the E Wagon dashcam. The E350 dashcam should be the same.

Also, I believe Collision Notification (a.k.a. Guard 360) is only for when the car is parked. It's not something that will give you photos in the event you are in a accident while driving. The dashcam is for that and limited to forward only. No rear option at all as far as I am aware.
BTW: Some advice to all is to read through old threads and use the search feature. The same questions are being asked over and over that would easily be answered with a little search effort. I found my post referenced above by searching.

I don't know the exact mechanics behind the GUARD 360 collision detection system, but I know it works for sure, as I personally experienced the system before and was able to see the vehicle that the impact occurred with.

I'm assuming the cameras are always recording in a looped buffer so it has the last x seconds at any given time. If an impact happens it saves those images, not video, for later review. The link I posted above has some images from a time a very loud exhaust triggered mine.

I tried searching "Guard 360" in the "Search Threads" box. That didn't help at all. Maybe I don't know how to search on MBWorld,

Thanks for all that input. The manual ua549 attached is 56 pages! But it sounds like for forward recordings it works good. I don't know about collision video or pics. I have the mercedes phone app. My car is in a specialty shop getting PPF and ceramic coating. Twice now, I got notification of "collision detected", with an aerial picture of generic car and a red line along the right driver side. The car would not be being driven during at the time of those notifications so somehow that detection thing works with the engine off. And if pictures or videos are available, I have no idea if/how to retrieve them. The shop tells me nothing at all has hit the car. Someone's @ss bumped it while working on it?

Looks good! I think the $200 is worth it. On a side note, I still don’t understand the feature (if I have it), a picture of a collision elsewhere on the car. The motor off? While moving? I might be getting things confused. I thought this is only a front facing dash cam as in the picture you sent.

If you have it, go into the settings for it and set up sending the pics to the app on your phone. Nothing like having the app tell you something has happened but not being able to see if it was real or a false positive until you get back to the car.

E450 Wagon, GLC300, E550
Several years ago, I parked my previous E450 wagon at the airport. After my plane was in the air, I noticed that the MB app was showing that my car window was open even though I was sure that it was closed when I had parked. I was concerned that someone may have smashed my window or otherwise broken into the car.
My wife called the MBUSA customer assistance number listed on the app, but they would neither confirm nor deny the status of my window and said that they were unable to do anything. Airport customer service refused to send their parking lot security staff or the on-site sheriff deputies to check the car for a possible break-in. My niece was working security at a local college and drove their marked car to the airport to check my car (security did allow her to enter the garage without paying, whooopi!). The window was up and the car was fine. But being 35,000 feet in the air moving farther and farther away from my car with no authorized officials nor MB willing to help me was a bit unsettling.
I hope the notification system on my new E450 works as advertised. I believe some BMWs allow you to remotely capture images from the car’s cameras whenever you want. It would be nice, and probably not a difficult software update, for MB to do the same. Between the external cameras and the interior selfie camera, it could provide peace of mind. I can’t think of a better use for the otherwise goofy selfie camera.
