It depends on the management configuration.
On a fully managed device, Android Auto requires the following to function:
The most common cause of Android Auto not working on fully managed devices is an overly restrictive app policy. If the organisation uses an app allowlist (only approved apps can run), Android Auto and its required companion services must be explicitly included.
For COPE (work profile on company-owned) devices, Android Auto runs in the personal profile by default and is generally unaffected by work profile policies.
If Android Auto fails to connect, check the EMM console for USB, Bluetooth, or app restriction policies that may be interfering.
