How it works in your Optima
The comma four mounts to your windshield behind the rearview mirror using a custom mount designed for your Kia Optima. The Kia-specific harness plugs into your car's existing LKAS camera connector — no cutting, no splicing, no permanent modifications.
Once installed, openpilot takes over your Optima's steering and acceleration on the highway. It keeps you centered in your lane, maintains distance to the car ahead, and can even change lanes when you signal. It's like having a co-pilot for your daily commute.
Installation takes about 30 minutes. We come to your location anywhere in the DFW metro, set everything up, and take you on a first drive so you can see it in action.
