Important for commissioning:
After installation, the car radio must be added/paired to the car using diagnostics so that it communicates correctly with the vehicle and works without restrictions.
Installation recommendations:
– Disconnect the battery before disassembly (it will reduce the risk of short circuits and errors in the electronics).
– Use the correct removal keys to pull the radio out of the dash, do not pull on the faceplate.
– Check the connectors and wiring (oxidation, loose pins, damaged insulation) and clean them if necessary.
– After installation, run the radio through diagnostics and then test the sound, backlight, signal reception and CD/MP3 function.
The reason why the part most often goes wrong:
The most common defects in these car radios are caused by wear and tear of the CD mechanics (laser, motor, drives), cold connections or a power failure on the printed circuit board. Fluctuations in the voltage in the car (weak battery, bad charging) or humidity in the interior, which accelerates contact corrosion and electronic malfunctions, are also frequent triggers.
