BigScrn

Setup

How BigScrn works

No app, no account with us, no cable. BigScrn is a launcher that lives in your car browser and points at the streaming sites you already pay for. First-time setup is about two minutes.

  1. Park the car

    The Tesla browser only runs in Park. The best time is at a Supercharger or while charging at home, the car stays awake and you have time to watch.

  2. Open the browser and go to bigscrn.com

    Tap the app launcher and open the web browser (the globe icon on most cars). Go to bigscrn.com and bookmark it so it is one tap away next time.

  3. Tap Go full screen

    Tap Go full screen on the launcher. BigScrn bounces the browser through YouTube, the one site Tesla opens full screen. Tap "Go to site" when YouTube asks, and you return full screen. The browser stays full screen from here on.

  4. Launch a service and sign in

    Tap Launch on any service and sign in with your existing account. The browser remembers it, so you only do this once per car. It opens full screen.

  5. Press play

    Start a title. It fills the display and audio plays through the car speakers.

Why the YouTube step?

Tesla's browser opens in a window that covers about two thirds of the screen, with one exception: it opens YouTube full screen. BigScrn uses that. The Go full screen button sends the browser to youtube.com/redirect, YouTube's own "leaving this site" page, with BigScrn as the destination. Because the page is on YouTube, the browser goes full screen; when you tap "Go to site" it carries that full-screen state back to BigScrn and keeps it for everything you open next. No app, no settings, no jailbreak.

Heads up: this relies on how Tesla's software treats YouTube, and Tesla has changed browser behavior in past updates. If a software version ever breaks the trick, the services still work in the normal windowed browser, just not edge to edge.

To leave full screen, tap Exit full screen on the launcher. That resets BigScrn (so launches stop routing through YouTube) and exits wherever the browser supports it. On Tesla, the windowed view returns when you tap the screen and use the browser's own controls or the app dock.

Why a launcher and not an app

Cars do not have an app store for video the way phones do. What modern EVs do have is a full Chromium browser on the center display. Every major streaming service runs as a website, so the browser is all you need. BigScrn just removes the typing: big, car-sized buttons that open each service and a guide for the few that have quirks.

Park only. Video streaming is for passengers and stopped cars. The browser is disabled while driving on purpose, and you should never try to watch video in motion.

What you need

  • A car with a built-in web browser (most Teslas, with more EVs adding browsers).
  • A data connection, the car's Premium Connectivity, a hotspot, or in-car Wi-Fi.
  • Accounts for the services you want to watch.

Not sure your car qualifies? Check compatible cars, then head to the launcher to start watching.
