# init(bluetoothIdentifier:iAP2Identifier:)

Creates a head unit object with the specified Bluetooth and iAP2 identifiers.

## Declaration

```swift
init(bluetoothIdentifier: String?, iAP2Identifier: String?)
```

## Parameters

- `bluetoothIdentifier`: The Bluetooth identifier of the vehicle’s physical head unit.
- `iAP2Identifier`: The iAP2 identifier of the vehicle’s physical head unit. This is the same value as the external accessory’s doc://com.apple.documentation/documentation/ExternalAccessory/EAAccessory/serialNumber.

## Discussion

Discussion The system uses these identifiers to match a vehicle in the user’s My Vehicles collection with its physical counterpart. You can’t change these values after initialization.
