What is the fine-grained topic of the following text: When ordering, you have a choice of the standard model which has a threaded hole in the cover for a Ram Mount ball (ball not supplied but available separately) or the Pilot® model which is supplied with the optional pilot cover with Ram Mount ball already fitted and featuring a Powerlet outlet (this is NOT a cigarette lighter style, it is a European Style for a more secure connection). Only return the topic.
