One-week free trial. TslaMirror is an app designed to mirror your iPhone apps to your Tesla’s built-in browser. - Supported apps include Waze, Google Maps, Apple Maps, YouTube, TikTok, Plex, and more. - DRM-protected apps, including but not limited to Netflix, Apple TV, YouTube TV, Amazon Prime Video, and Hulu, are not supported. Some DRM-protected apps may block video mirroring, resulting in a black screen in the Tesla browser. Instructions for the Tesla built-in browser: 1. If possible, update your Tesla’s infotainment system to the most recent version. 2. Make sure the vehicle is PARKED (0 mph / 0 km/h). 3. Connect your Tesla to your iPhone Personal Hotspot (cellular data required). MCU2 or MCU3 hardware is required: available on Model 3 and Model Y, Cybertruck, Model S built after March 2018, Model X built after March 2018, or vehicles upgraded from MCU1 to MCU2/3. 4. Ensure the iPhone is not in Low Power Mode. Launch the TslaMirror app and toggle on “Proxy.” 5. Tap “Start,” then select “Start Broadcast” to begin screen broadcast. 6. In your Tesla’s built-in browser, go to https://TslaMirror.com 7. Lossless audio playback is supported in the browser. 8. Keep your iPhone unlocked; due to Screen Broadcast API limitations, locking the screen stops casting and requires restarting the broadcast. Key Features 1. No additional internet traffic is used for mirroring; traffic stays on the iPhone’s Personal Hotspot. However, while the Tesla is connected to the hotspot, the vehicle may use your cellular data for its own internet access. 2. Private: the screencast is only available to devices connected to the iPhone Personal Hotspot Wi-Fi network. 3. A 5 GHz Personal Hotspot (supported from the iPhone 12 series) is highly recommended. Do not enable “Maximize Compatibility” on iPhone 12 models; enabling it forces a 2.4 GHz hotspot. 4. H.264/H.265 mirroring recommendations: - MCU3 (AMD Ryzen): H.265 mode with 720p@60 fps recommended, as 1080p requires higher bandwidth. MCU3 supports up to 1080p@60fps (H.264 and H.265). - For Tesla in-car system software version 2025.38.11 and later, H.265 mirroring is now recommended for both MCU2 and MCU3. - MCU2 (Intel Atom): H.264 mode with 540p@30fps recommended only for very old Tesla in-car system. FAQ 1. This is not CarPlay. 2. iOS apps that use the AVPlayer framework (e.g., Apple Music, Netflix) are not supported. 3. Netflix is not supported.
