Upgrade Guide

How to upgrade from comma two to comma three

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

Secure harness

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 4

Plug the RJ45 Cable into the harness

Ensure the cable is fully seated.

Step 5

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 6

Plug the comma power into the OBD-II port

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

Step 7

Plug the OBD-II cable into the harness

Ensure the cable is fully seated. For comma three, ensure the straight end is connected to the harness box.

Step 8

Reinstall the rearview mirror cover trim

Ensure the car harness fully fits inside the trim. Have the OBD-C cable come out of the top.

Step 9

Mounting prep

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

Step 10

Place mount high and centered on the windshield

Ensure the top of the mount is fully visible from the driver's seat.

Step 11

Adhere mount

Peel off the 3M tape on the mount. Press firmly in the center of the mount, then the edges. Ensure no bubbles form.

Step 12

Let the mount cure

The mount must cure for 48 hours before installing the comma device. Skipping this step will compromise the integrity of the mount.

Step 13

Clean camera lenses (comma three only)

Clean all three lenses with the included microfiber cloth.

Step 14

Plug in OBD-C and mount the device

Plug the OBD-C cable into the back of the comma device. Make sure the cable is all the way in.

Step 15
