To solve this, a (like Peugeot's PP2000 or a high-end multi-brand scanner) is required to "telecode" the radio to the new car. This is not something a service manual can solve without the proper equipment. Some specialized electronics services offer to reprogram the VIN for you.
Unit shows no display, no button backlighting, and does not draw current on a bench power supply. Diagnostic Steps:
Apply a thin layer of specialized white lithium or silicone grease to the plastic gears and sled tracks of the CD loading mechanism.
