I restored a 1 of 4 '89 Carroll Supercharged 350 VHO Formula 3 years ago that had a GM radio with CD. It was locked, lit up but didn't work, had the "triangles of death" showing, etc. I sent it to United Radio in NY, Angelo Rivizzi. They did a GREAT job making it new again and turned it around in about a week. Wasn't that expensive either. Can't say enough about them.
