I just picked up a new Lexus RX 350h and I'm absolutely loving the quiet ride, but I really want to get a dash cam installed for peace of mind. Since this is a hybrid with a lot of sensitive electronics and safety sensors near the rearview mirror, I’m a bit nervous about a complicated hardwire job. I’m looking for something that offers a super clean, OEM-like look without cables hanging everywhere. Has anyone tried those Fitcamx units that replace the mirror cover, or is a plug-and-play OBD-II power cable a better route? I’d prefer a 4K resolution if possible. What’s the easiest setup you’ve found that won't mess with the Lexus Safety System+ 3.0?
Hello, you can take a look at here:
For your situation, I would suggest looking into a more budget-friendly and less invasive route if you're worried about the Lexus Safety System+ 3.0 sensors. I totally get being nervous about the Fitcamx; while it looks OEM, messing with that plastic housing near the mirror can be a pain if you ever need warranty work.
Instead of a complex hardwire, you should honestly check out a high-quality 4K unit paired with an OBD-II power cable. It's basically the ultimate "lazy" pro hack. I've been running the Vantrue E1 Lite 1080P WiFi Mini Dash Cam in a similar hybrid setup, but since you want 4K, definitely look at the VIOFO A129 Pro Duo 4K Dual Dash Cam. You can grab the Vantrue OBD II Hardwire Kit for like $20-$30, which literally just plugs into the port under your dash. It provides constant power for parking mode without you having to touch a single factory wire or fuse box.
Basically, you just tuck the thin cable into the A-pillar weatherstripping and you're golden. No splicing, no risk to the hybrid battery system, and it's 100% reversible. If you're shopping for deals, keep an eye on the VIOFO A119 V3 2K Dash Cam too—it's not true 4K but the image quality is so crisp it might as well be, and it’s way cheaper. Just make sure to get a high-end endurance card like the SanDisk 256GB High Endurance UHS-I microSDXC so it doesn't flake out on you in the summer heat. gl! 👍
For your situation, I totally get the nerves. I just went through this with my own Lexus and honestly, the whole "sensitive electronics" thing is a real concern if you're hacking into factory wires. I actually tried a few different setups and had some frustrating results before finding what worked, so I feel u.
Here's what I recommend based on my trial and error:
1. Go with [[Fitcamx]] if you absolutely must have that factory look. It literally replaces the plastic housing behind the mirror. But tbh, I had issues with the app being super glitchy and the 4K quality was not as good as expected for the price. It's basically a trade-off between looks and performance.
2. Just get any high-end unit from [[Viofo]] or maybe [[Vantrue]]. You cant go wrong with these brands for actual image clarity. They are lowkey the gold standard for reliability right now.
3. Avoid the OBD-II cables if you can. I tried one and it actually kept my car's computer from "sleeping" properly, which drained the battery. Not worth the headache on a hybrid, you know?
4. The REAL pro tip? Look for a mirror power adapter (sometimes called a Dongar cable). It's a little plug-and-play dongle that taps into the power already going to your rearview mirror. It gives you a USB port right where you need it. No running wires down the A-pillar and zero risk of messing with the Safety System+ 3.0 sensors.
Honestly, I wasted a bunch of money on kits that didn't work right before settling on the mirror tap method. It's the cleanest way to get 4K without the hardwire drama. gl with the new RX, it's a sweet ride! 👍
Story time: I went through this last year and tbh it was such a headache trying to save a few bucks.

Sooo, I actually tried a few different ways. First, I grabbed the Fitcamx Dash Cam for Lexus RX 4K cuz I wanted that factory look. Honestly though? I had issues with the plastic clips—they felt super flimsy and I was terrified of snapping something near those expensive sensors.
Comparing that to a Dongar Dashcam Power Adapter (10-pin Type B for Lexus) paired with a Garmin Dash Cam 67W, the difference in stress was huge.
**Fitcamx vs. Dongar Adapter:**
- **Fitcamx:** Looks amazing (totally invisible), but the installation was way more finicky than the videos make it look.
- **Dongar Adapter:** Basically plug-and-play into the mirror power. It's way cheaper, but unfortunately, ur limited on where u can tuck the extra wire.
I really wanted that 4K, but after messing with the housing, I kinda regretted not just going the simpler route from the start. Just sharing my experience... it's not as easy as it looks! gl!
Any updates on this?
