GoKawiilWhile most apps will work just fine over a VPN, Android Auto isn't a traditional app. Rather than making its own network requests, it works as an extension of your phone by routing data through predefined APIs designed for a distraction-free driving experience. Because a wireless connection to Android Auto relies on a direct local Wi-Fi link between the phone and the car, system-level networking features like VPNs and custom proxy configurations can prevent it from connecting.
What is split tunneling, and how does it help?
Split tunneling is a common VPN feature that lets you choose which apps go through the encrypted tunnel and which ones connect directly to the internet. Therefore, instead of routing all your phone's traffic through the VPN, you can carve out exceptions for specific apps.
For Android Auto, this means the app gets the direct connection it needs while everything else hides behind encryption. That's ideal for browsing, banking apps and other sensitive activity.
Of course, split tunneling isn't just for Android Auto. Any app that requires a direct internet connection should use it, such as certain smart home platforms, streaming services and gaming apps.
