Certain I answered this the other day... but can't seem to find the post/thread.
These are no longer made. I was lucky enough to get one of the final ones from BAVauto in the US a few months ago. I believe they had about 6-10 units on back order from BMW Atlanta Parts dept, all of which have been sold.
I ordered one through their competitors, BAVAuto, in Nov 2014. By April 2015, I still hadn't had mine delivered, with simply an email saying "expected next month" each month... Fairly certain they will not be back in stock as BMW no longer make them, sadly!
Ive done a good little fit in the ashtray just useing the normal aux cable i got from BMW and no tools for about £10. Il get some pictures up to follow. Looks better than the one your talking about.
found this one http://www.bavauto.com/shop.asp
