A home screen that opens up something new

An unofficial home screen that replaces the stock launcher on your car. It shows you what the car already knows, in the places the car never showed you. Taking over the instrument cluster works on the Sealion 7 only.

On the car

Key features

Everything below is photographed on a real car. Only what works gets a picture. Broadcast pictures and station logos are blurred out.

Cluster — Sealion 7 only

The instrument cluster photographed in four drive modes — Eco in green, Snow in blue, Sport in red and Normal in teal. Each shows five dials: road speed, GPS speed, motor rpm, torque and motor temperature, with battery, range and odometer along the bottom. — Instrument cluster — the colours follow the drive mode (Eco, Snow, Sport, Normal). Sealion 7 only

The car

The dashboard on the centre screen: cards for range and battery, outside temperature, charging state, odometer, door locks, this trip and average efficiency. — Dashboard — range, battery, charging, odometer, door locks, efficiency

A grid of vehicle control tiles — boot, lock, child locks, sunblind, ambient light, daytime running lights, windscreen defrost, rear-window and mirror heating, airflow and headlights — under tabs for locks, lights, climate, seats, comfort, charging and alerts. — Vehicle controls — boot, locks, lights, heaters, climate (the ones you use go in Favourites)

Cameras

The instrument cluster in Eco green with the left indicator lit and a round side-camera view opened on the left, showing the car parked alongside in a garage. The five dials and the range, power and odometer readouts stay visible. — Turn-signal camera — indicate, and that side's camera opens on the cluster

The centre screen split into four live camera views labelled front, rear, left and right, filmed while driving on a motorway with a coach alongside. A line underneath reads that recording is running, with the frame count and how much of the card is used. — Dashcam — front, rear, left and right on one screen, recorded as you drive **Next update**

Map and broadcast

The map screen with the map itself blurred for privacy. The position marker and the zoom buttons stay sharp, and the radio panel sits alongside it. — Map — where you are, with the radio alongside (the map is blurred — it is home)

A grid of Korean radio station tiles with the broadcaster logos blurred, and the station now playing on the right with a level meter. — Radio — Korean stations over the internet (broadcaster logos blurred)

Live television filling the centre screen with the picture blurred, and a row of channel tiles below with their logos blurred. — TV — live broadcast on the centre screen (picture and logos blurred)

Regions — navigation, the speed-camera warnings, radio and TV run on Korean data and Korean broadcasters (Kakao Mobility, public camera data). Weather, music, the vehicle controls, the turn-signal camera and the dashcam work anywhere. The instrument cluster — the screen beyond the steering wheel — is the Sealion 7 only; on the ATTO 3 and the Dolphin it is the centre screen.

Manual

What each screen holds, and what every item in Settings does. The app itself carries no explanations — Settings is for operating, not reading — so the explanations live here.

Open source we learned from

The Sealion 7 and ATTO 3 launchers were built with help from the public research below. No code was taken — the implementation is written from scratch. What these taught us is what the head-unit software calls things and in what order. Without them this would have taken weeks longer.
