I am looking t replace my headunit with a double din panasoinc dvd player. My questions are
1. do i need the 100 dollar harness for my 06 cobalt ss/sc
2. how do i go about transferring my Xm radio from factory to the new product if it can be done.

 

Go to crutchfield.com and put the car info on the site and they should tell you everything you need. Their customer service is top notch; call them up and explain what you want to do. I called them one about how to remove a dash on a friends truck. I didn't even buy the XM from them and they still helped! I told them, I'm a customer, but my buddy wasn't.
