Respectfully, I'd consider another option before jumping on the integrated mirror housing style. I've been messing with Cadillac electronics for over a decade, and while those integrated ones look clean, they often use cheaper sensors that struggle with the heat build-up behind the windshield, especially in a performance car like the CT4-V.

In my experience, if you want that OEM+ look without sacrificing 4K clarity or parking mode reliability, the best move is a high-end compact unit tucked behind the mirror. You can actually tap into the power in the overhead console using a simple adapter so you aren't tearing the whole dash apart.

Here is what I've found works way better long-term:

* BlackVue DR970X-1CH Plus 4K UHD Dash Cam - This thing is tiny. If you mount it right, you literally can't see it from the driver's seat.
* Dongar Dashcam Power Adapter 10-pin Type H for Cadillac - This is the secret sauce. It lets you pull power directly from your autodimming mirror plug. Zero wires running down the A-pillar.
* Samsung PRO Endurance 256GB microSDXC Memory Card - Trust me, dont cheap out on the card; these cars vibrate a lot and you need something that can handle the constant writes.

I mean, Fitcamx is okay if you're just casual, but for a V-series, I'd want the better bitrate and cloud features. Just my two cents after seeing a few of the plastic housings warp over time. Hope this helps ur build! peace

For your situation, I recommend looking at Vantrue E1 Nano Dash Cam or the BlackVue DR770X-1CH Single Channel Dash Cam. Fitcamx is okay, but if you want real performance metrics, Viofo VS1 Mini Dash Cam uses a better Sony Starvis 2 IMX675 sensor that handles glare way better than the integrated housings. Ngl, those sleek shells look cool but usually lack the bitrate for high-speed CT4-V driving. Basically, stick to a tiny wedge unit for that low-profile look!

For your situation, safety and reliability should be the top priorities, especially since performance driving in a CT4-V can really test how well things stay attached to your windshield! Honestly, I wouldn't mess with those unbranded integrated housings; they look sleek but often lack proper thermal management, which is a HUGE risk for your car's electrical system if they overheat.

Here's what I recommend for a clean, pro-grade setup:

1. **Safety-First Reliability**: I've been running the Thinkware U3000 Dual Channel Dash Cam with 4K UHD Front and 2K QHD Rear and it's basically the gold standard. It uses a Sony Starvis 2 sensor which handles heat way better than those knock-off integrated units.
2. **The "Semi-Integrated" Look**: If you want it hidden, mount a BlackVue DR970X-2CH Plus 4K UHD Dash Cam right behind the mirror on the passenger side. It's a slim cylinder shape, so from the driver's seat, it's literally invisible.
3. **Pro Hardwire**: Instead of a DIY tap, get the BlackVue B-130X Ultra Magic Battery Pack. This keeps the camera isolated from your Cadillac's sensitive main battery, preventing any "Battery Saver Active" warnings on your dash while still getting 24/7 parking protection.

Basically, the BlackVue is so small you won't even notice it's there, plus it won't fry your overhead console electronics!! gl with the new ride! ✌️

yo, congrats on the CT4-V! i'm kinda new to the Cadillac scene myself, but i spent like *forever* researching this exact thing cuz i hate messy wires too. basically, you've got two main ways to go:

1. **The Integrated Look**: Fitcamx actually does make a model that swaps out the plastic shell behind your mirror. i think it looks basically factory-spec. it draws power from the rain sensor so you don't gotta run wires to the fuse box. it's super stealthy but maybe has fewer features than high-end brands.
2. **The Hardwire Route**: honestly, some people just grab a sleek unit and use a 'MirrorTap' or hardwire it into the overhead console. it takes more work, but you get better video quality imo.

so basically, if you want easy/clean, go with the integrated shell. if you want the best specs, go for a tiny dash cam and a mirror power adapter. gl!

Seconding the recommendation above! Honestly, i'm with reply #2 about the heat issues on those integrated housings—totally not worth the risk if it fries ur electronics. Plus, those custom setups can get crazy expensive. If ur on a budget, just grab a standard wedge-shaped cam and tuck the wire into the headliner. It literally takes ten minutes and saves u like $200. Clean look, way better sensor quality, and way cheaper... honestly a win-win.
