Hey, guys. I did a search and couldn't find anything. Is there any way to still get OnStar to work with an aftermarket stereo? I put one in my '05 Tahoe and now OnStar won't work. I can't subscribed, but I'm thinking about it and need my hardware to be in line before I do. Thanks.

There are a couple different harnesses. The one I always use is made by Metra: GMOS-04. This will retain your On-star, Bose, RAP ,and chimes.
