Untested GM car radio+CD stereo

This is an untested GM RDO assembly car stereo that has been collecting dust in my garage since around 2017, part number 20918590. It's assembled in Mexico and complies with 47 CFR Part 1040 and 47 CFR Part 15 of FCC Rules. This unit is a direct replacement for vehicles requiring this specific model. Great for restoring your car's original audio system!
