I have a unused OnStar antenna that I will sell for $70 plus shipping which I estimate to be around $15.00 but will confirm when needed. I bought this for my 2008 Denali but ended up not needing it and decided to keep it for some reason. It has been taken out of the box to look at but never installed. Still have original packaging. Picture below is off of the internet. Can provide photo of actual item if necessary.
