What is the best dash cam for a Cadillac Lyriq?

Question

Hey everyone! I finally took delivery of my Cadillac Lyriq last week, and I’m absolutely in love with the ride quality and that massive LED display. However, now that the 'new car anxiety' has set in, I’m getting a bit nervous about parking it in public lots and dealing with daily traffic. I really want to install a high-quality dash cam to protect this investment, but I’m hitting a few roadblocks and could use some advice from the community.

Since the Lyriq is such a tech-forward EV, I’m a little worried about how a dash cam might interface with the electrical system. I’ve heard mixed things about hardwiring into the fuse box on the Ultium platform—does anyone know if this triggers any system errors or affects the 12V battery health? I’m looking for something that offers a very clean, factory-like look. With that beautiful interior, the last thing I want is messy wires hanging down or a giant suction cup blocking the view of the road.

I’m specifically looking for a setup that features both front and rear coverage, and a reliable 'parking mode' is a must-have for me. I’ve been looking at brands like BlackVue or Vantrue, but I’m curious if there’s a specific model that fits well behind the Lyriq’s rearview mirror assembly without interfering with the safety sensors or the digital rearview mirror camera. My budget is around $400-$600 for a solid setup, including installation.

Has anyone here successfully installed a dash cam in their Lyriq yet? If so, which brand/model did you go with, and did you use a MirrorTap or a traditional hardwire kit to keep the cabin looking tidy? I'd love to hear your recommendations on what works best with our specific hardware!

For your situation, I would suggest looking at the BlackVue DR970X-2CH Plus 4K UHD Dash Cam with a BlackVue B-130X Ultra Slim Battery Pack. I've been messing with car electronics for a decade and honestly, tapping into the 12V fuse box on an Ultium EV like the Lyriq can be super finicky and might trigger those 'Service 12V System' errors if the voltage drop is too high while parked.

Here is what I recommend after years of trial and error:

* **Go with a dedicated battery pack:** Instead of hardwiring directly to the fuse box for parking mode, use the B-130X battery. It charges while you drive and powers the cam when parked, so it literally never touches your car's 12V battery while the car is off. Basically saves your battery health, right?
* **The MirrorTap route:** If you just want the front cam powered cleanly, the MirrorTap MT-4015 Power Cord is great for grabbing power from the rearview mirror harness, but it wont support parking mode.
* **Clean Look:** The Fitcamx 4K Dash Cam for Cadillac Lyriq is actually the best for that factory look cuz it replaces the plastic shell behind the mirror. It's super stealthy, tho some veterans prefer BlackVue for the better cloud features.

Be careful with the rear wire routing near the side curtain airbags... make sure to tuck it behind them, not over them! GL!

yo! honestly, i totally get that new car anxiety. i've had my Lyriq for a few months now and i was literally in the same boat wanting to protect that gorgeous front end. before you jump in, it's basically crucial to understand that these EVs are super sensitive with their 12V systems, so you dont wanna just tap into any random fuse or youll get those annoying errors.

for your situation, i actually went with a setup that looks totally factory and i'm sooo satisfied with it. here is what worked for me:

* Fitcamx 4K Dash Cam for Cadillac Lyriq - this is the way to go if you want that clean look. it replaces the plastic shell behind the mirror so there are no wires hanging down at all, seriously!
* Vantrue N4 Pro 3 Channel 4K Dash Cam - if you want that rear coverage too, this is a solid beast, but you gotta be careful with the wiring.
* SAMSUNG PRO Endurance 256GB microSDXC UHS-I U3 V30 - dont forget a high-end card cuz cheap ones die fast in parking mode.

i actually used a MirrorTap for the power and it hasn't messed with my digital mirror at all. plus, the sensors are all clear! i mean, it might be a bit of a tight fit but it works well. good luck!

Saw this earlier but just now responding! Honestly, I totally agree with what was said about using a separate battery pack—it's basically the only way to go if you want reliable parking mode without stressing that sensitive 12V system. In my experience, these Ultium cars get real cranky with any extra parasitic draw.

You might find this useful—check out the Cadillac Lyriq section over at the Cadillac Society forums or LyriqForums.com. There are some GREAT threads there where people share photos of their MirrorTap setups and show exactly which wires to tap into without breaking anything.

Pro tip: If you want that factory look, look into the brand FitcamX. They make a model specifically for the Lyriq that replaces the plastic trim behind the mirror. It looks TOTALLY stock and stays well within your budget. Also, check Dashcamtalk for sensor reviews so you don't overpay for marketing hype. GL with the new ride! 👍
