Re: iPhone/iPod duplicating songs when connected to Terrain
This topic has been addressed in a previous thread. I have been to the dealership, talked to GM's infotainment customer service, and tried multiple resets of my iPod and the car settings. The Infotainment service rep is trying to find a dealer in my area that has the new diagnostic tool and set me up an appointment with them.
To give you an idea of how far I went with this, I completely wiped my ipod and my itunes of all songs, reloaded them and verified that the song information (ID3 tags) were up to date with the correct info. After going through this, the problem only got worse. Now the iPod won't even play in the car.
The only thing that makes sense to me is that the radio keeps some song location/information data stored for each device connected through USB. When a device changes some of this information, the radio has a hard time dealing with it. I am happy (well, sorta) to see that this problem isn't just me and my iPod. I will keep updating on what information customer service gives me, and whether of not the new diagnostic tool works.
