Enable Android Auto while keeping your VPN active with split tunneling
Android Auto can now run alongside a VPN by using split tunneling or a wired connection, preserving privacy without losing in-car features.
Android Auto fails to start when a VPN is active, showing a "Communication error 21" message, because the service relies on an unmediated Wi-Fi connection between phone and car. Most VPNs offer a split-tunneling feature that lets specific applications bypass the encrypted tunnel; adding Android Auto to this exclusion list restores functionality while the VPN continues to shield other traffic. Users may need to reveal system apps in the VPN settings or turn off the kill-switch if Android Auto remains hidden.
Some providers, such as NordVPN, can automatically detect and exclude incompatible apps. For those who prefer a simpler solution, a wired USB link to the vehicle allows both Android Auto and the VPN to operate together without additional configuration.
Why it matters
It lets drivers keep online privacy while still using navigation and media in their cars.
