While I think that I now understand Bob J.'s thinking on this play, I just don't think that I can apply one sentence in what seems to be an exception for the purposes of one play in the case book and apply it to this particular situation. The differences are sufficient to make me think that the two plays (viz., this GPS and gaining possession while on the floor) are apples and oranges.
So, I am sticking with my original answer, especially now that Drake and TH have chimed in and agreed with it.
I'd feel a lot better if Bob agreed with me too. But you can't have everything.
Where would you put it?
There's no violation on the play in question.
