Step 1

Remove the rearview mirror cover trim

Removal method varies by car. The durable plastic often requires a strong tug to pop it off on Hondas. Toyotas often need a slide outward. If you’d like to see how it’s done, find a comma installation guide for your specific make on YouTube.

Step 2

Plug your harness into the camera

Unplug the existing LKAS camera connector and plug it into the harness. Now, connect the other end of the harness back into the LKAS camera.

Step 3

Plug the RJ45 Cable and USB-C into the harness

Ensure they are fully seated.
Step 4

Secure harness and cables

Find where to place the harness box so the trim can still be installed over it. Peel off adhesive sticker and attach the harness in place.

Step 5

Put your trim cover back on

Tuck the USB-C cable in to the trim to the right of the rear view mirror area. Return the trim to its place.

Step 6

Route the RJ45 cable to the OBD-II port

The RJ45 cable must be brought across your car to your OBD-II port which is almost always found below the steering wheel to the left. Carefully run the cable behind the vehicle trim along the windshield, doorframe, or dash.

Step 7

comma power V2 into the OBD-II port

Plug the RJ45 cable into the comma power V2 and then plug the comma power V2 into the OBD-II port.

Step 8

Mounting prep

Clean the mounting area with the included alcohol wipe and let it dry.

Step 9

Adhere mount

Attach a mount to the comma two. Peal off the 3M tape on the mount. Mount the device high and centered on the windshield pointing directly outward. Ensure the screen is fully visible from the driver's seat. Use light pressure to mount the comma two.

Step 10

Secure mount

Pull the comma two off the mount. Press firmly in the center of the mount, then the edges. Ensure no bubbles form. Let the adhesive cure for 48 hours.

Step 11

Plug in USB-C and re-mount the comma two

Plug the USB-C cable into the back of the comma two. Make sure the cable is all the way in when the comma two turns on. Slide the comma two back on the mount and follow instructions on the screen to get started.
