Hi, ok I'm in the process of having a 2008 S550 4Matic shipped to me tommorow. One item I noticed that is missing and please forgive me for my ignorance because I have no GD idea what these devices are called but it's either a dongle?? or a puck?? I think, it inserts into the center console for BT connectivity. Does anybody have any idea how I know which one to buy??? Somebody told me it was the B67875878 model but then when I looked this up to see if my phone was compatible, it didn't list my phone on there. So here's my question, I have a crackberry (Blackberry) Curve 8530, does anyone know if I can pair this to whatever dongle I have to buy, or do I have to get a different model phone???

Thanks so much, and again, please excuse my ignorance in this arena.
