Success:

Royaltek RBT-3000 BT GPS...w/Routis 2004.
HP TC1100 Tablet PC.. did some simple BT dialup networking connections, need to explore more

Anyone try to pair with the BMW Bluetooth built-in hands free kit? I have a BMW 330i and want to get it, but would love to hear others experiance with it. Seems from my reseach that everything "should" work since all appropiate BT profiles are suppported by the h6315.
