My GMC Radio does not have any tags out side or inside however a decal fell out of it when I removed the back. The decal says Radios and wheel covers, 2718 Koper Dr., Sterling Hts, Michigan 48077. Phone 313-977-7979, When I called the number it was disconnected and an internet search got zero results. Just to be safe I found a local radio club and the president gave me a member to contact to have it checked out. More to follow. I know I am being super cautious. One of my many sicknesses.
