Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →To check which computer your Tesla has, open Controls > Software > Additional Vehicle Information on the touchscreen. To check whether a software feature is available, review Controls > Software, the feature package shown for the car, and the vehicle’s touchscreen Owner’s Manual. Tesla does not publish a complete model-by-model RAM chart or a universal memory threshold for each feature, so don’t infer memory capacity from a model name or computer generation.
How to identify the computer in your Tesla
- On the touchscreen, open Controls > Software.
- Tap Additional Vehicle Information and read the AI computer type displayed for that vehicle. Tesla gives this route in its Infotainment Upgrade information. If the car is set to another language, use the equivalent labels on its screen.
Use the computer type shown by the vehicle rather than guessing from its model, trim, or year. Tesla Mexico’s AI computer page, for example, says owners who purchased Full Self-Driving (Supervised) and have computer 2.0 or 2.5 qualify for a free upgrade to computer 3.0. That is a localized Tesla statement, not a universal offer; check Tesla’s current information for your market and vehicle.
How to check whether a software feature is supported
Check the software screen and update status
Open Controls > Software to see the installed software version and whether an update is available. You can also check the Tesla app. Tesla rolls updates out over time, and cars may receive them at different times. Its Software Updates guidance describes the Advanced update preference as receiving updates as soon as they are available for that vehicle’s configuration and region. Tesla says this preference requires software update 2019.16 or later; it does not make an unsupported feature compatible.
Check the feature package, not just the computer
For Full Self-Driving (Supervised), Tesla instructs owners to look in Controls > Software for Full Self Driving Capability in the included package and for the Full Self-Driving (Supervised) Software entry. The car must complete an over-the-air software update before those features become available. The package, installed software, and computer type are separate checks: finding one does not by itself establish that every related feature is available.

Tesla says feature availability can vary with the vehicle’s configuration, hardware, software version, region, model, trim, and model year. Its Full Self-Driving (Supervised) support page puts it this way: “Specific features available to you may vary depending on your vehicle configuration, hardware, software version, region, model, vehicle trim and model year.”
Use the manual for that specific car
Open the Owner’s Manual on the vehicle touchscreen when you need operating instructions or vehicle-specific details. Tesla says the touchscreen manual is customized to the car’s purchased features, configuration, market region, and software version. Its Model S Owner’s Manual software-update section also explains that software updates are delivered over the air and that availability can vary.

Does a USB drive give the Tesla more computer memory?
No. A USB drive used for Dashcam or Sentry Mode is external storage for recorded video. It does not increase the vehicle’s internal computer memory or change which software features the car supports.
For the 2020–2024 Model Y Owner’s Manual, Tesla specifies these requirements for USB video storage:

The same manual says larger drives can hold more footage. Its examples say a smaller drive may hold as little as one hour before overwrite and a drive of 1 TB or more may hold up to 24 hours. These are examples, not guaranteed recording times for every configuration.
Port support also varies. Tesla warns that on some vehicles built after approximately November 1, 2021, center-console USB ports may only charge devices. The manual directs owners to use the glovebox USB-A port when fitted. Check the manual for your exact vehicle and supported port before buying storage.

What “more memory” can and cannot tell you
Tesla’s owner-facing material identifies an AI computer type and describes feature eligibility for a particular vehicle; it does not establish a complete RAM-capacity table by model or a numeric memory requirement for each software feature. Computer generations should not be converted into unverified RAM amounts. Nor do these materials describe adding desktop-style RAM as an owner upgrade.
For a real compatibility decision, check the computer shown in the car, the software and included package, and the vehicle-specific manual. When an upgrade or feature depends on eligibility, confirm it with Tesla for the car’s market and configuration.
