You just got a new model bluetooth phone, and after trying it out, you finally want to connect it to your bluetooth car kit in your new bimmer, but there is a problem, the two refuse to talk. Contacting manufacturers of both products, proves futile. To the rescue, a bluetooth bridge, that lets your cell phone think it connects to say an audi car kit(which is supported), and to your bmw car, the cellphone looks like a Motorola razr, that is suppored by the car kit.-- romanmar, Apr 14 2006random, halfbakery
