Overview
The GKU D600 is a mid-range front-and-rear dash cam with 4K recording at the front, 1080p at the rear and phone-app controls. It ranks #1 in our list of the top 10 best-selling dash cams on Amazon UK, with an 8.8/10 score and our Best overall award. Its strong combination of dual-camera coverage, included storage and owner feedback makes it a well-rounded option on paper. The Cievie D100, ranked #2, also sits in the mid-range, while the premium 70mai A810 Lite at #3 is positioned for drivers prioritising connected parking. The D600’s main parking-mode catch is that it needs a separately sold hardwire kit.
Features and specification
The front camera records in 4K and the rear in 1080p when used together; the listing says the front camera can record in 4K on its own. A 170-degree field of view, F1.8 aperture and WDR are listed, though actual detail in difficult night conditions can depend on road lighting, speed and camera placement. The kit includes a 64GB microSD card and supports cards up to 256GB. Loop recording overwrites older footage when storage fills, while the G-sensor is designed to lock clips after a detected impact. Owners can adjust settings, view footage and download clips through the GKU GO app over 2.4GHz or 5GHz Wi-Fi. The listing gives a short 3–5m Wi-Fi range and says remote connection is not supported. Parking monitoring offers impact-triggered and time-lapse modes, but both require the compatible hardwire kit, which is not included. Voice prompts and a compact windscreen-mounted unit round out the feature set.
What owners say
Owner feedback commonly praises the straightforward installation, clear footage from both cameras and the convenience of downloading clips through the app. Several buyers say the supplied card and cable-routing tool make setup easier, and some appreciate that the front unit can be tucked behind the rear-view mirror. Owners also report useful night-time footage, although that does not guarantee number plates will be readable in every situation. Criticism is more modest but worth noting: one owner found the app slow, and another said the G-sensor sometimes locked clips after driving over cattle grids. A buyer who needed to replace the windscreen mount also struggled to source the sliding attachment separately. These experiences suggest checking the mount position and sensitivity settings after installation.
Who should buy it
Consider the GKU D600 if you want front-and-rear recording, an included memory card and app-based clip access without moving into a premium-priced setup. Its substantial owner feedback and reports of manageable installation make it appealing to drivers fitting a dash cam for the first time, provided they are comfortable routing the rear-camera cable. It is less suitable if you expect parking surveillance straight out of the box: budget for the compatible hardwire kit and installation, or choose a simpler powered setup if parked recording is not essential. Treat the 4K label as one part of the decision; reliable positioning, a clean windscreen and easy access to saved footage matter too. Overall, it offers a persuasive feature mix, with the extra parking-mode cost and a few app or sensitivity niggles as the main reservations.

The verdict: 8.8/10
The GKU D600 is a strong all-round choice if you want dual-camera coverage, 4K front recording and app access in a mid-range package. Buy it if those features suit your needs, but factor in the separate hardwire kit if you want parking mode; skip it if you expect that protection to work without extra parts.
Best for: Drivers seeking a capable front-and-rear setup from a model with a large body of owner reviews. Skip it if: You want parking mode ready to use without buying a compatible hardwire kit separately.
