Story time: I went through this last year when I first got my EQS and honestly, I was terrified of touching anything near that Hyperscreen. I mean, one wrong move and you're looking at a massive repair bill, right? I spent weeks looking for a cheap way to get 4K footage without paying a pro $500 for a custom install.

I actually tried the "DIY budget" route first by looking for those mirror tap cables. I found the Dongar Technologies Dash Cam Power Adapter 10-pin Type H for Mercedes-Benz which is usually around $30. It's basically a Y-cable that steals power from the autodimming mirror. It seemed like the holy grail because it's so cheap compared to a $300 custom housing kit, but I hit a snag. The EQS mirror housing is TIGHT. Like, seriously tight. I struggled for an hour trying to tuck the adapter and the extra wires inside the plastic shroud without snapping the clips.

In the end, I realized:
- The Dongar Technologies Dash Cam Power Adapter is a great money-saver if you're patient.
- Pairing it with a small unit like the Vantrue E1 Lite 1080P WiFi Dash Cam keeps costs under $150 total.
- But... hiding the wires in the EQS mirror assembly is a total pain compared to older cars.

I kinda regret not just spending the extra cash on the integrated look from the start, but if you're on a budget, the mirror tap is the way to go. Just be careful with those plastic pry tools! Anyway, hope that helps a bit lol.

For your situation, I would suggest looking at Fitcamx 4K Dash Cam for Mercedes-Benz EQS V297. Honestly, I've used their stuff for a few years on different cars and it is basically the closest thing to plug-and-play you'll find.

Sooo, here is the deal:

- It replaces that plastic shell behind the mirror, so it looks totally OEM.
- The best part? It uses a Y-cable that taps into the rain sensor power. No pulling apart the dashboard or running wires to the fuse box, which is a huge relief for that Hyperscreen setup.
- You can get it for around $180-$200 on their site or Amazon, which is way cheaper than the Mercedes store options.

Just be careful cuz since it draws from the mirror/sensor, you might not get a 24/7 parking mode unless you actually hardwire it. But for 4K quality without the headache of a pro install, it is probably your best bet. Make sure to get a good card like the Samsung PRO Endurance 128GB microSDXC Memory Card so it doesnt fail on you. Good luck with the new ride!! 👍

Same here!

For your situation, I'd really suggest looking at the integrated mirror shell options from brands like Fitcamx or similar OEM-style manufacturers. So, before you dive in, you gotta understand that the EQS electrical architecture is super sensitive. Basically, the MBUX system monitors every single milliamp, so if you tap into the wrong wire or use a cheap hardwire kit, you're highkey gonna trigger a 'Battery Standby' error or worse. That's why I always tell people to prioritize circuit integrity over everything else.

In my experience, the safest way to handle this without ripping the dash apart is using a rain sensor Y-harness. It literally just sandwiches between the factory plug and the sensor behind the rearview mirror. No cutting, no splicing, and no running wires down to the fuse box where things get messy with the airbags. It's basically the cleanest way to maintain the safety standards of the car while getting that 4K feed you want.

I've seen too many DIY jobs go south because people try to save fifty bucks on a generic kit and end up frying a SAM module. Honestly, just stick with the dedicated Mercedes-fit brands that offer the plug-and-play harness. It might cost a bit more, but it’s way safer for your warranty and your sanity lol. If you're still worried though, maybe just have a tech at a reputable shop look at it? But yeah, the mirror tap is definitely the move if you wanna avoid the 'Christmas tree' dashboard lights. gl!

Seconding the recommendation above regarding the mirror shell kits! Honestly, if your worried about the warranty, those are the safest bet. I've done a ton of market research on this and basically, you should also look at the Mercylion G800-A 4K Dash Cam for Mercedes-Benz EQS or the Peztio 4K Dash Cam for Mercedes-Benz V297. Both are solid alternatives to the Fitcamx and use the same Y-cable rain sensor tap so there's no cutting wires. Just be careful though... even with these, you gotta ensure the harness is seated perfectly or the MBUX might throw a fit. If you're really nervous, maybe just have a local tech do the 15-minute install? Peace of mind is worth it! gl

Spent some time thinking about this and wanted to add a few warnings for the DIY route. Even with the easier kits, there are some serious risks to keep in mind:

• Avoid using any metal tools to pry the plastic; those clips are fragile and you will definitely leave marks on the trim.
• Make sure the wiring doesnt interfere with the camera sensors for the lane-keep assist, as even a slight shift can cause calibration issues.
• Be mindful of the heat buildup behind the mirror housing, especially if you live in a warmer climate, because the EQS electronics are sensitive to thermal limits. Im always a bit paranoid about the interior anyway. Last week I spent nearly two hours just trying to find a specific type of lint-free cloth because I noticed a tiny smudge on the corner of the Hyperscreen. It felt like a surgical operation just trying to wipe it down without leaving swirl marks in the coating. Honestly, I think I spend more time cleaning the dash than actually driving the car lately. Anyway, just be careful with those plastic tabs during the install. But yeah.

Solid advice 👍
