PAC-Audio lists their OS-2C OnStar harness as compatible with NON-Bose 2005-2010 Corvette Radios. I called their T/S line and asked whether it would also be compatible with the 2013 non-Bose. He told me that the OS-2C was as yet "unproven" to work with the 2011-2013 non-Bose's. Now two questions:

1. Has anyone successfully used the OS-2C harness with a 2011-2013 non-Bose?

2. Are there any differences between the 2010 non-Bose head units and the 2011-2013 head units?

Any light you can shed on this problem would be greatly appreciated!

Thanks!

GM changed something somewhere around '11 in C6, the PAC units work but they have a lot of static/noise in them for some reason. I'm fairly certain you need to use the GMOS to retain onstar and have it sound good. Without onstar get the C2R-GM24.

Thank you Mark, I appreciate the tip! We're going to try the GMOS-4. I'll post something about the results.
