Sorry if this has been posted, but I'm pondering installing a blazer overhead console and I'm wondering what this round vented thing is between my visors. (I was thinking onstar mic?)
A working On-Star could be selling point when the time comes. If you do decide to remove it, tuck it away somewhere safe so that it can be made functional again is needed.
If you have bluetooth, it would be for phone calls as well. I was going to do an overhead console, but never found one that I liked enough to modify it to fit.
