Hi, I just bought my 2013 HS a few weeks ago and it was cleverly equiped with an USB port attached to the GPS pigtails. I even heard that suggestion here so I went to look and check it out and that is when I discovered it had already been done. But when I plug my iPhone into it nothing happens , I even tried two cables both of which work so it's not the cable. Any ideas on how to troubleshoot this? My first thought was to check the fuses but I don't see which one is for the GPS...
