Can anyone please explain to me how to get my IPhone to play music every time in my SG stereo? The salesman had it working at the dealer when I bought it,it has been hit and miss for me when I got it home. The manual is as clear as mud;sometimes I can find it on the menu and sometimes I cant! I feel like an idiot 'cause I cant figure it out. The radio around her bites bigtime and my playlist is the great! Help!
