Introduction

Do not forget to eject the navigation CD-ROM before you disconnect the unit.

This guide does not show you how to remove the unit from the car.

Follow this guide in case that has happened to you.

  4. It is advisable to grab an old CD and push it half way into the CD-ROM drive until it is visible through the hole marked in the first picture. This will prevent the part that has to be removed in this step to fall down into the unit, with the risk of damaging the laser. The metal plate slides forward as shown in the first picture. Use a pair of tweezers to very carefully slide forward and then lift up and remove the metal plate together with the white plastic disk, if they fall into the unit you are going to have to take it apart completely (using this guide).

    • Dip one end of a cotton swab in rubbing alcohol.

    • Lightly dab the swab on the lens. Be very gentle.

    • Let the lens dry before putting the unit back together.

Hi, Michael. Maybe it's too late, but:

1. Yes, the screw was very tight. I unfastened it like with an impact screwdriver: simultaneously pressed down and turned. Only a quality tool will do the job

2. When You remove the screw and the spring You can detach the white plastic ring. At that moment You need a CD to prevent the ring falling down

3. After You have tied the ring You can remove the CD and lower the ring inside the unit to gain access to the lens

4. Yes, the CD-ROM reads original disks without problem

Sorry for my english, also. TI hope that helps
