# Advanced configurations

## **Maximum number of vehicles**

A user can declare one or more vehicles. If you need to limit the number of configurable vehicle(s), you can set the parameter `maxVehicles`**:**

```

* A strictly positive integer
* `nil` : If you do not want to limit the number of configurable vehicles.

**Default value:** `nil`

## **Authorization to add a vehicle**

In some cases the vehicle can be pre-configured or you do not want the user to add a vehicle himself. Depending on your needs, it is possible to allow or restrict the vehicle to be added by the user. Call the following method to enable/disable the configuration:

```swift
DriveKitVehicleUI.shared.enableAddVehicle(enable: Bool)
```

**Settings:** 

* `true`: the user can add a vehicle
* `false`: the user cannot add a vehicle

## **Configure vehicle actions**

The Vehicle UI module lets you manage the actions available to the user that can be performed on the vehicle. 

You can select the features that are visible and accessible to the user as well as the order in which these features are displayed. The possible actions are : delete the vehicle, replace the vehicle, rename the vehicle, technical data display and manage the vehicle mileage.

You can select which actions you want to display by calling the following method:

```swift
DriveKitVehicleUI.shared.configureVehicleActions(vehicleActions: [VehicleAction])
```

**Settings:**

* `delete`: the user can delete the vehicle.
* `replace`: the user can replace the vehicle.
* `rename`: the user can rename the vehicle.
* `show`: the user can display the vehicle characteristics. 
* `odometer`: the user can enter a mileage value manually.

**Default values: \[**`.show`, `.odometer`, `.replace`, `.rename`, `.delete`**]**

## **Authorization to delete a beacon**

If automatic trip recording with a beacon is mandatory in your application, you can block the deletion of a beacon and only allow its replacement. You can enable or disable this function using the parameter: `allowDeletingBeacon`.

**Settings:** 

* `true`: The user can delete a beacon
* `false`: The user cannot delete a beacon

**Default value:** `true`
