I was wondering the very same thing as I drove to work this morning!. Sorry I can't help, but I can add my pending thanks to anyone who shares the answer.
They are very directional, so hiding it is not a great one I'm afraid. Really it needs to be in front and above you as much as possible on all the kits I have every had or seen. They tend to lose the pic-up very easily if they are aligned either directly above or facing the wrong way. The MINI one may be different though
