I purchased a Belkin 3.5 jack cable to hook up my Ipod nano to my Smart Passion to be able to listen to my music. Connected it to ipod and the jack in the glove box. Turned on the radio system in the car and pushed the button to AUX No sound coming out through the car speakers. I know the nano is on, the song is selected and "playing" Am I missing a step here somewhere? The volume is up, I checked that. Any ideas what could be wrong?
