How to watch Max in a Tesla
Max (formerly HBO Max) streams through the browser and Tesla Theater. Premium accounts unlock 4K on devices, the in-car player tops out at the display resolution either way.
Step by step
-
Park the car
Streaming only runs in Park. Shift into Park and keep the car awake, a charging stop is the ideal moment.
-
Open BigScrn in the car browser
Open the in-car web browser and go to bigscrn.com. Bookmark it so it is one tap away next time.
-
Tap Go full screen
On the launcher, tap Go full screen. BigScrn bounces the browser through YouTube, the one site Tesla opens full screen. Tap "Go to site" when it appears and you land back full screen, and the browser stays that way.
-
Launch Max and sign in
Tap Launch on Max and sign in with your account. The browser remembers it, so you only sign in once per car. It opens full screen.
-
Press play
Start a title. It fills the display and audio plays through the car speakers.
Shortcut: On supported cars, Max is also in Tesla Theater (Entertainment, then Theater) so you can skip the browser entirely. The browser route still helps for extra profiles or cars without Theater.
Questions
Does Max work in a Tesla?
Yes. Max runs in the Tesla browser while the car is parked, and it is also a built-in Tesla Theater app on supported cars. Both routes need a sign-in.
Do I need a Max subscription?
Yes. You watch with your own Max account, the same login you use on a phone or TV.
Can I watch Max while driving?
No. Streaming only works in Park, and you should never watch video while the car is moving. BigScrn is for passengers and parked, charging cars.
Where does the Max audio play?
Through the car speakers. Set the volume on the steering-wheel scroll or the on-screen control as you would for music.
Is BigScrn part of Max?
No. BigScrn is an independent launcher and setup guide. It is not affiliated with Max, Tesla, or any streaming service.
