Code

Int64
    interval = 1000 * 60 * 1,
    fastestInterval = 1000 * 50;

try {
    GoogleApiClient
        googleApiClient = new GoogleApiClient.Builder( this )
            .AddApi( LocationServices.API )
            .Build();

    googleApiClient.Connect();

    LocationRequest
        locationRequest = LocationRequest.Create()
            .SetPriority( LocationRequest.PriorityBalancedPowerAccuracy )
            .SetInterval( interval )
            .SetFastestInterval( fastestInterval );

    LocationSettingsRequest.Builder
        locationSettingsRequestBuilder = new LocationSettingsRequest.Builder()
            .AddLocationRequest( locationRequest );

    locationSettingsRequestBuilder.SetAlwaysShow( false );

    LocationSettingsResult
        locationSettingsResult = await LocationServices.SettingsApi.CheckLocationSettingsAsync(
            googleApiClient, locationSettingsRequestBuilder.Build() );

    if( locationSettingsResult.Status.StatusCode == LocationSettingsStatusCodes.ResolutionRequired ) {
        locationSettingsResult.Status.StartResolutionForResult( this, 0 );
    }
} catch( Exception exception ) {
    // Log exception
}

With this code, if the locationSettingsResult.Status.StatusCode is LocationSettingsStatusCodes.ResolutionRequired ( 6 ) it means -- probably -- that the Location is turned off, although I've found one situation that it didn't return the value when the device had the option turned off. After turning on and off, it worked, might be a bug on the device, or not.
