Have a question regarding my radio for my Chevy. Recently my radio fried due to some really unforseen circumstances. The small screen on top is working though, still has a visible screen. My car is a 2011 model and my question is to those who have gotten a replacement how much was it to replace from the Chevy agency? I know I'm probably going to find one used and I don't really want an aftermarket as I actually liked the default radio and might plan to sell the car in the long future. Thanks for taking the time to read my post.
