Hi I just recently became the owner of a 2008 Chevy cobalt LS I love the car the minute I test drove it it reminded me of my 04 cavalier are used to have I love that car as well my oh he has a few problems nothing I can’t handle pretty sure I know what it is just gotta get the parts and of course it’s nothing serious I do have a question though my factory stereo screen is not working appropriately the radio works and all that just you can’t really see the screen a friend of mine gave me a factory stereo out of a 2009 cobalt my question is are they interchangeable and if so is it like plug and play or do I go to have some programs
