played my girlfriends ipod for the first time in my 06 530 xi t. i do have logic 7 and sat radio. the car did not come with the ipod adapter. so, we plugged it in to the lighter. it sounded muffled and she commented that it sounded as though the music was not coming through the door speakers. i switched back and forth to sat radio and there was ahuge difference. any thoughts/advice as to what is causing this?
