Front 4K & Rear 1080p Dash Cam for GMC Sierra Select 1500/2500/3500

In this review of the Front 4K & Rear 1080p dash cam for GMC Sierra Select models, the bottom line is simple: this unit is for owners who want an OEM-style, hidden installation and high-resolution front and rear recording. The reviewer found it especially useful for 2014-2021 Select 1500 and 2015-2023 Select 2500/3500 Model E trucks that already have an auto-dimming rearview mirror plug, because that built-in power option lets the camera integrate cleanly and power on with the vehicle without messy exposed wiring.

Key Features

• Custom fit: The dash cam mounts behind the rearview mirror for an integrated, factory look that keeps wiring out of sight and preserves dash aesthetics.
• 4K front recording: Front camera captures high-resolution 2160P video for clear license plate and road detail in daylight conditions.
• 1080P rear camera: The included rear cam records at 1080P to provide a reliable back view for incidents and parking situations.
• Built-in WiFi and free app: Wireless connectivity and an app let users view live video, download clips to a phone, and transfer footage to a PC without removing the memory card.
• Loop recording and G-sensor: Continuous loop recording overwrites old files while the G-sensor locks footage automatically when a collision is detected.
• Complete kit: The package includes a 128GB microSD card, OBD power adapter, auto-dimming mirror plug adapter, installation tools, and a rear camera with cable for out-of-the-box setup.

Who It's For

This dash cam is best for GMC Sierra owners who want an OEM appearance and a tidy installation that tucks the unit behind the mirror, particularly Select 1500 owners from 2014-2021 and Select 2500/3500 owners from 2015-2023 Model E. Buyers who value a high-resolution front camera and a usable 1080P rear feed will appreciate the clarity and the included 128GB card for longer recording times.

It is not suited for vehicles that lack the Auto-Dimming Rearview Mirror Plug Power Adapter unless the owner is willing to hardwire to the fuse box or use the provided OBD adapter for parking monitoring. Shoppers who need a simple plug-and-play USB accessory for any vehicle should look elsewhere.

Pros & Cons

Cons

• Requires an Auto-Dimming Rearview Mirror Plug Power Adapter for the Model E fit; otherwise additional wiring via OBD or fuse box is needed for full functionality.

Our Verdict

This dash cam is a solid choice for GMC Sierra Select owners who want a clean, factory-style installation and strong front-facing video quality at 4K.
