Hardwiring the BlackVue DR770X Box 3-Channel Dash Cam

Aside from the unique design, the DR770X Box also boasts BlackVue Cloud which can be connected instantly with the CM100G LTE module. Of course, hardwiring also activates the parking mode features. This can be activated if you hardwire the DR770X Box to your vehicle’s fuse box, which can be done through the free hardwiring kit from BlackVue.

Take note that hardwiring is optional. If you do not want to use the DR770X Box's parking mode, you can install it using the 12V power connection and your car's cigarette power outlet. However, hardwiring is highly recommended to get the most out of this three-channel setup.

When we hardwire a dash cam, the first step we do is to locate the vehicle's fuse box or power source. The fuse panel may be located under the steering wheel, and for some European cars, in the rear compartment or in the trunk.

Looking at the hardwiring kit of the DR770X Box, it consists of three wires: the yellow wire for constant power, the red wire for accessory, and the black wire for the ground bolt. If you're not sure which wire is which, you can always refer to the labels on the hardwiring kit.

Checking out the Box, the unit is independent of the cameras and houses the BlackVue dash cam's processor, WiFi connection, and memory card. We recommend putting the main unit in the glovebox, under the seat battery style, or in the trunk on a situational basis. As for getting the Box unit into the glovebox, some vehicles will allow you to take off the side paneling to run the cables behind and into the glovebox, while some vehicles may require some drilling to run the cables through. Make sure to loop the wires behind the airbags if they do go from the side panels.

Also, the DR770X Box includes some Velcro strips in the package. This is useful in installing the Box itself, which is quite similar in installing a Battery Pack. You can add the Velcro strips attached against your carpet, or just under your car seat, and you can easily take it off and put it back as needed.

Another thing to note is that the Box includes a GPS module. This GPS module will need to be wired from wherever the Box is, to a windshield for reception reasons. If you would install the CM100G LTE module for 4G LTE connectivity, this can will replace the GPS.

All three cameras will be fed from the main box unit rather than a single primary camera.

After installing the Box, we need to mount the DR770X Box’s front cam. Unlike other BlackVue dash cams, the front camera of the DR770X Box is designed small - the same size of the rear and interior cameras. While the cameras themselves look the same, ensure you are installing specifically the front camera in the front, as it records in 60fps rather than 30, and has the built-in Mic. The Lens cover for the front camera will have a 1 written inside, while the lens covers for the other models will have a 2 written. For us, we recommend hiding it behind the rearview mirror towards the center to keep it out of sight.

Cleaning the windshield is also necessary simply to ensure that the camera adheres properly. After you've adhered it to the windshield, hold the adhesive against the windshield for about 15 seconds to allow it to set.

Once your front camera is already neatly mounted, it's time to work on the main event - wiring.

Once all the wires are connected, plug the kit into your dash cam. Before you hide the cables away, make sure to start the car to ensure that your dash cam powers on. If the dash cam powers on, it means you did everything right.

To hide the wires, remove the cover of your car’s A-pillar. Navigate the cable behind or around the airbags and to the front cam tucking in the cables neatly into the roof panel. These plastic panels, for the most part, simply pop off if you need to remove them.

If it works, you can go ahead and tidy up the cables - you don’t want any cables to be dangling from the dash cam or around the fuse box. The best way is to tuck the loose cables inside the fuse box loose area and along the A-pillar of your car. Zip ties and electric tape are your friend as they help keep things tight and out of the way.

Again, we recommend you not to wait until after you've tucked away all your wiring to plug in and test your camera as it will typically be easier to troubleshoot when the wires are readily accessible.

Now, it’s time to mount the Blackvue DR770X Box’s Interior Camera. The interior camera comes equipped with infrared LEDs, enabling it to record in complete darkness. We want to put it behind, on the left side of the rear view mirror so that it gets a good view of all the passengers. Ideally, running the cable along the same pathing as the front one is ideal, though it may differ if you prefer a different location for the interior camera.

Following the front and interior camera, we'll move on to the rear camera.

The next step is to route the cables for the rear cam. Wipe the rear windshield first, as you did with the front and interior camera, before positioning the rear camera at its best angle.  

Route the rear coaxial cable along the headliner, past the A, B, and C pillars on the passenger side. Using a Trim Tool or other device to get in there can be helpful, and BlackVue’s thin coaxial cabling makes the process a breeze!

Note that it should not be installed on the rear defroster grid lines. Make sure to close up all the panels after you’re done! Same as the front camera, you’ll want to check the live-view of the rear camera before mounting, making sure it’s up and running, and using the positioning lines accordingly.
