E350 line in audio not working
 

Hi Gang,

The van is under warranty so I can go to the dealer but I just picked up a 2011 E350 with 12,000 miles. I noticed that the line in for audio doesnt work. I tried different sources and different cables but all i get is silence. I wish to play my Sirius and my iphone throught it.

Not sure if it is related but, I also noticed that I have two cigareete lighters (12v) on the dash and the one on the left doesnt work. I checked the fuses and I think they looked ok.

one of those cig lighters isnt a lighter its a charging plug in. use a multimeter to see if theres any power comin from the line in port if not might need a new stereo
