I am disconnecting from XM Radio this week and want to try and hook up my RAZR through my GM Terrain USB Port. I quickly tried today with no luck. Has anyone been able to connect and can please tell me the steps? Also, I have been searching my phone for the location of music files. I know they exist, because when on airplane mode I see a few files that are playable. Yes, I have checked my music folder, and there is nothing in it. Also, no music is on the SD Card. Thank You for your guidance.
