When working on electronic components, make sure the work area is clean and dust free.
Make sure your hands are clean and free of oils and grease.
The audio-navigation unit and HDD are mated and cannot be
substituted separately. If you need to substitute a known-good unit for
testing, substitute a complete known-good audio-navigation unit and HDD.
Static electricity can damage the HDD. Always follow proper handling procedures.
Always use the anti-static mat (ESD) and wrist strap when
removing the HDD. Before you open the audio-navigation unit or handle
the replacement HDD, attach the wrist strap around one of your wrists,
and attach the alligator clip to the ESD mat.
Make sure you use the screws in the same holes. The HDD can be damaged if the wrong screws are used.
You do not have to peel off the plastic cover to remove the screws or the HDD.
Do not force the HDD. If it does not slide in smoothly, check the
alignment of the HDD and the pins. If the pins are bent, replace the
HDD.
Make sure the HDD screws are not loose. If they are, the HDD can be damaged.
Handle the HDD by its edges. Do not touch the pins.
