I am in the market for a new head unit for my 2003. I was wondering if someone knew if the stock radio had any RCA jacks on the back of it, like an aftermarket one does. I am pretty sure it doesn't but wasnt sure. Trying to save myself some time in diggin into the dash to look. I also have onstar and all that jazz in my vehicle as well, and was wondering if the wiring harness for an aftermarket head unit would take care of all of that stuff, or if i needed to do something different. I have done a lot of installs in the past however nothing with as many options on it as this one.

Any help would be greatly appreciated!!
Thanks in advance,
Ben
