So my gf just got an 2002 E39 525i on the cheap. The car still has the stock head unit and rather than lose all of the functions built into the stock unit, is there a way to use Spotify through any kind of smart phone? Ive done some casual searching and have seen 'DICE' mentioned as well as this:

I'm just wondering if these are the best courses of action. The phone in question would be a Blackberry.
