Before installation, locate the small switch labeled "Active Control" on the side of the Screenmate One and move it to the RIGHT position using a paperclip or SIM tool.
Setup Steps
Prepare for Installation
Before touching the dashboard, watch the installation guide for your specific Tesla model all the way through at least once. The install itself is straightforward, but forcing connectors could make this project very expensive very quickly. If you are unsure about any step during installation, ask in the Discord before continuing. A quick question is better than replacing an MCU.
First Boot & System Access
Once your Screenmate One is installed, press four fingers on the Tesla display at the same time. The screen should switch to the Screenmate logo. After approximately 20–25 seconds, the Screenmate One OS should appear.
Connect to Wi-Fi & Update
Open Wi-Fi settings and connect the Screenmate One to your home network before doing anything else. Once connected, launch the Screenmate Updater app and press Check for Updates.
If your device is on update 1.0.5 or updates to 1.0.5 you'll need to download and open Firefox on the Screenmate One and visit:
http://screenmate.co/fix-update
Follow the instructions there to be able to update to 1.0.6.
Flash Video MCU & CAN Updates
After updating to the latest firmware, open the Screenmate Flasher app and run the following updates in order:
During flashing, the Tesla display may flicker, reboot, or temporarily return to the native Tesla interface. This is normal. Wait for the flasher screen to return before proceeding to the next update.
Do not interrupt power or force reboot the Screenmate One while flashing updates.
Configure GPS & Mock Location
The Screenmate One uses GPS data from the Tesla CANBUS for Android location services. To ensure GPS works correctly, open Android Developer Options and confirm the Screenmate app is selected as the mock location provider.
After enabling mock location, drive the vehicle for a few minutes. The Screenmate One should begin receiving GPS location data automatically.
If you don't see the developer options, you may need to enable them. Go to Settings → About Device. Scroll down to the bottom of the screen and press the Build Number over and over again. Eventually you'll get a popup that developer options are enabled.
Finalize Configuration
Open the Screenmate app and review every settings category carefully. Most options include tooltips explaining exactly what they do, including Bluetooth integration, audio routing, steering wheel controls, and Tesla-specific behavior. After that, you're all set. Feel free to sign into Google, install apps from the Play Store, configure your streaming services, and enjoy having Android integrated directly into your Tesla display.
