There are several levels of accuracy: POOR (Accuracy 300 meters), FAIR (Accuracy 300 meters), MODERATE (Accuracy 200 meters), GOOD (Accuracy 100 meters), EXCELLENT (Accuracy 50 meters with GPS), IDEAL (Accuracy 40 meters with GPS) to be able to save or find your car position you need to have at least the GOOD level Accuracy.
