YOUR CAR SCREEN, UNLOCKED
YouTube, TikTok, IPTV, your own videos and music — and any app on your phone — on the car screen. Plus a speedometer, call alerts and trip statistics. Works over wired or wireless Android Auto, or directly on an Android Box.
THREE WAYS, ONE APP
Install once — the app works out where it is running. Open it without Android Auto connected and CarStream asks which mode you want; touch nothing and it enters Box mode after 6 seconds.
Android Auto
Connect your phone to a car with Android Auto — wired or wireless. Your phone becomes the remote.
Box mode
An Android Box mounted in the car, or a phone not connected to Android Auto. No Android Auto needed — the box is the head unit.
Phone app
History, trip statistics, find your parked car, settings and account sign-in. Five tabs: Control · Watch · Stats · Find car · Settings.
In Box mode and Android Auto connects? The app switches to the controller view; disconnect and it asks again. Both ways are automatic — no restarting the app.
WHAT IT DOES
Mirror your whole phone to the car screen
Any app on your phone can run on the car screen, with touch control right there. Split into 2, 3 or 4 windows at once. Needs Android 11 or later; pair once inside the app — no computer required.
Turn-by-turn navigation on the car screen
NewSearch by typing or voice, pick one of three routes, and follow step-by-step guidance with a speedometer. Turn arrows and distances also show on the HUD / instrument cluster. In Google Maps on your phone, tap Share → CarStream and the car starts guiding. The Map add-on is sold monthly or yearly.
Seven home styles, full of widgets
NewKeep watching, Frosted glass, Stage, Map, Floating panel, Bento, Ribbon — pick from real previews and the whole app restyles to match. Swipe through cards: weather, air quality, fuel prices, phone battery and signal, recent calls, messages, and your own payment QR. Videos play right inside the home card.
Every trip, logged
Turn on Record trips and each drive is saved with distance, time, speed and an automatic fuel cost. Routes are drawn on a real map; view by day, week, month or year.
Forgot where you parked? Find car
NewWhen you leave Android Auto the app saves your parking spot — or tap Save spot now. The Find car tab shows a map, the address and a radar arrow pointing to your car.
Something for everyone on the road
Movies, clips and favourite channels on the centre screen. Kids in the back stop complaining and long drives feel shorter — no phone taped to the dashboard.
Ad-free YouTube, sponsor segments skipped
Ads are cut before the page loads, including mid-roll — no waiting for “Skip”. Sponsor segments inside videos are skipped too. On TikTok, ad clips still appear.
Music keeps playing when you open Maps
Switch to navigation and the audio carries on — no choosing between music and directions.
Eight sources — show only what you use
YouTube, TikTok, VTVgo, FPT Play, IPTV (your own M3U list), Phone for local videos and music, games (enable in Settings) and a real web browser. Hide what you don’t use; turning it back on keeps its settings.
Steering wheel, voice and car keyboard
Play, pause and skip with the steering-wheel buttons. Voice search — if your car only has a next button, press it twice to open the mic. Or type with the car’s keyboard.
Rotary knob works too
NewCars with a rotary knob and 4-way pad like Mazda: turn to select, press to open — move through home, Settings, YouTube, VTVgo and the launcher without touching the screen. Hold Back to show or hide the side bar.
Speedometer and speed-limit alerts
A draggable speed bubble in eight styles. Speed limits come from CarStream itself — no third-party app needed — and VietMap, Gofa, Waze and Wyn are supported too. Can be sent to a HUD or LED odometer display.
Sign in once, use everywhere
Sign in on your phone and the car screen is signed in too — one shared session. Stop halfway on the phone, then tap Keep watching in the car to continue.
One install, three tiles on the car screen
CarStream to browse and watch, CarStream Full for borderless full screen, CarStream Control as the “now playing” tile where steering-wheel buttons and voice go. All three from one install.
Picture tuned to your car screen
Three player-bar styles, crop-to-fill for square screens, data saver for music over 4G — or 2K/4K if your screen is sharp enough. Light/dark follows your phone, or your headlights — lights on, dark mode on.
10-band equaliser
New10 bands from 31 Hz to 16 kHz with 7 presets — tune it on the car screen or the phone to suit your speakers.
Zalo and Messenger calls on the car screen
Watching full screen when someone calls? A bar pops up on the car screen: caller name, hang-up button and an icon showing which speaker the audio uses. No need to pick up the phone.
Choose on the phone, the car follows
The Watch tab on the phone is a real browser — pick something in your hand, turn on Sync to car screen and the car opens the same page.
Vietnamese or English
NewThe whole interface — phone and car — is available in English. Switch in Settings › Language, no reinstall.
REAL, IN THE CAR

The Map add-on is bought separately for 6 months or 1 year — with a key, or on its own for an existing key. Prices on the Buy a key page.
Seven home styles
- Keep watching · Frosted glass · Stage — plus four map styles: Map · Floating panel · Bento · Ribbon.

The four map styles need the Map add-on. The default is Keep watching, as before.

An Android phone, or an Android Box in the car. iPhone is not supported — CarPlay doesn’t allow third-party apps like this on the car screen.
A car with Android Auto — or a Box
Wired or wireless Android Auto both work: if Google Maps shows up when you connect, you’re good. No Android Auto? Use Box mode on an Android Box.
