This seems to work great so far. Was easy to assemble and I feel safer when driving knowing it'smonitoring me and everyone around me.

I didn't know how to install it, but after contacting Mangoal customer service, the problem was solved and the dashcam is now working properly.

I recently outfitted my Buick Envision with this 4K dash cam and I'm thoroughly impressed by its seamless integration and outstanding video quality. The custom fit for the Buick Envision 2016-2020 is perfect!it looks as if it were an original part of the vehicle, without any unsightly wires or awkward placement. Installation was a breeze, especially since I have the power dimming rearview mirror. Simply connecting the Y cable to the mirror's power supply and attaching the dash cam made the setup swift and straightforward.

The video quality of the dash cam is a major highlight. It records in Ultra HD 2160P, providing crystal-clear footage regardless of the time of day. This high-resolution recording is essential not just for capturing scenic drives but also for ensuring that any incidents on the road are recorded with the utmost clarity.

Overall, this dash cam has proven to be a fantastic investment for my Buick Envision. It not only enhances my driving experience by providing security and peace of mind but also maintains the elegant look of my vehicle's interior. For any Buick Envision owner, this dash cam is a perfect choice, combining utility with sophistication in a way that few other products do. Whether it's day or night, the quality of the footage and the ease of use make this dash cam a top recommendation.

Upgrading your Buick Envision with the Mangoal 4K Dash Cam is an excellent choice for enhancing both the functionality and luxury of your vehicle. The installation process was smooth, though I opted for professional help to ensure everything was set up perfectly lol. It was worth it, as the dash cam fits precisely and operates flawlessly. Make sure to check your specific model (Model A in my case) to match the dash cam perfectly to your vehicle's style. The video quality is great! Images are crisp and clear, no matter the lighting. The dash cam also allows for quick video downloads to your smartphone through a free, user-friendly app. Included in the package are all the necessary accessories, including a 128GB MicroSD card, which is a generous addition that ensures you're ready to go right out of the box. Also, the comprehensive 12-month warranty and friendly customer service provide peace of mind.

Mangoal has carved out a niche in the highly competitive dash cam business not by competing on cutting edge specs, but on aesthetics. More specifically, they allow you to install a very servicable dash cam without compromising the OEM interior design. I'm sure most people understand the value of a dash cam (front, back or both) but not everyone wants something hanging down from the rear view mirror.

The cam itself might not be on the cutting edge of performance and hardware specs but it does a decent job. Video quality is decent, night vision functionality is solid and it delivers all of the features you need (integrated smartphone app, loop recording, motion sensing, etc.). If you really want high end specs/performance this isn't the dash cam you need. If you want something that offers solid dash cam functionality without messing up the interior of your vehicle this is the product for you. Recommended!
