hi, i have just bought a car cit by satechi. ive succeeded to connect it with the fm station, and to pair it with my iphone via bluetooth. but after it is paired, im going into the "ipode" in my iphone, and when i start playing music, it is playing through my iphone and not through the car speakers/ what am i doing wrong? is there some kind of a function in the iphone i need to know about before i start playing music?
