iPod won't play music in my car through USB.
I recently bought a 2011 Buick LaCrosse CXS with the premium audio system and navigation. The system is supposed to play iPod through a USB port. My iPod Touch hooks up fine and shows albums/songs on the navigation screen and the song appears to play. The cursor moves along the progress bar but there is no sound. The iPod plays fine through headphones and on several devices in my home.
The USB <-> iPod cord had a kink in it so I replaced it even though it syncs with my computer fine. Still no music from iPod to car.
I tried my daughter’s iPhone and it plays fine in my car. Someone said that maybe I need to update the firmware on my iPod, but I can’t figure out how to do that. Where do I get the firmware? I suppose the site where it is downloaded will have instructions for installation. Currently I have in Settings/General/About: Model = MA672LL AND version = 3.1.3 (7E18).
I’ve updated my iTunes software to the latest 10.5.0.142. I’m not convinced that firmware is the problem but this is a place to start unless someone has other suggestions.
Thanks for your help.
