Pro tip: I looked into this for a client's 2026 Buick and unfortunately, while the Fitcamx mentioned above is the standard choice, the 2026 refresh actually tightened up some tolerances around the sensor housing. It's kinda annoying tbh, but you might wanna compare two other options I've tested for that technical 'factory' integration.

Option A: Vantrue E1 2.5K Dash Cam with GPS and Speed + Dongar Dashcam 10-Pin Type H Power Adapter for Select GM.
Pros: Using a mirror-tap like the Dongar is way cleaner than running wires to the fuse box. You get a super small footprint that hides behind the mirror.
Cons: Not a full housing replacement, so you'll see a tiny bit of the mount, but it's very discrete.

Option B: Thinkware U3000 4K Dash Cam with Radar Sensor.
Pros: Technically superior because of the Sony Starvis 2 sensor and the radar which saves battery.
Cons: It's way more expensive and much bulkier than the integrated housing style, so it might mess with the sleek look youre going for.

I've had issues with some generic mirror-tap kits not fitting the new 10-pin GM connectors on the 2026s, so definately double-check your pin count before ordering anything. If you want 4K without the bulk, the Dongar adapter paired with a small cam is probably ur best bet for a clean setup !! gl with the new ride.

Ok so, I went through this last year with a different GM refresh, and honestly, the safety sensor housing is always the trickiest part. In my experience, even when the dash looks identical, the clips inside can change slightly between years, which makes the 'factory look' installs a real pain if the plastic doesn't line up perfectly.

Over the years, I've tried many different setups because I'm paranoid about blocking the ADAS sensors or messing with the airbag deployment zones. I eventually moved away from the integrated shells and tried the Garmin Dash Cam 67W paired with a SimpleUSB Mirror to Dashcam Power Adapter for my 2026 Buick. It's not a full housing replacement, but it's sooo tiny that it basically hides behind the mirror anyway.

I've found that prioritizing a high-quality sensor like the BlackVue DR970X-1CH Plus 4K UHD gives better peace of mind for long-term reliability than just chasing the cleanest plastic trim. Safety-first is always my motto cuz you don't want a loose cable or a bulky housing interfering with your emergency braking sensors during a close call!

TL;DR: I've found that using a mirror-tap with a micro-sized 4K camera is often more reliable for refreshes than forcing a custom housing that might have tight tolerances.

Hope that helps with the new ride! 👍

TL;DR from this thread: You've basically got two paths for that 2026 Buick Envista. You can go with the integrated Fitcamx 4K Dash Cam for Buick Envista 2024-2026 for that stealthy factory look, or try a more universal setup if the sensor housing tolerances are too tight on the refresh. Honestly, I'm all about the budget-friendly DIY route to save some cash. If you want to avoid the $150+ price tag of integrated units, you can grab a 70mai Dash Cam M300 1296P for like $50 and pair it with a SimpleUSB Mirror to Dashcam Power Adapter for about $20. It's not 4K, but it's super tiny and hides behind the mirror perfectly without any wires dangling to the floor. Basically, if ur trying to keep it under $80 total, a small cylindrical cam + mirror tap is the way to go imo. It keeps the dash looking clean without breaking the bank! 👍

In my experience, you're 100% on the right track wanting that OEM look because the Envista's dash is way too clean for messy wires. I've been using the Fitcamx 4K Dash Cam for Buick Envista 2024-2026 and I'm seriously happy with how it turned out. It basically replaces the plastic shell behind the rearview mirror, so it looks like it came from the factory.

Here is why it works so well:
* No wires: It uses a Y-harness to tap power right from the rain sensor/mirror plug.
* 4K Quality: Honestly, the video is super crisp, even at night.
* Discrete: You literally can't see it from the drivers seat.

I paid about $170 for mine and it's totally worth the premium over a clunky suction cup unit. Just make sure you get a high-end card like the SanDisk 128GB High Endurance microSDXC Card so it doesn't fail on you. Installation took me like 15 minutes, tops. gl with the new ride! 👍
