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.

This guide contains the least amount of steps to clean the lens. In case you drop the white plastic disk that holds the CD-ROM down (step 2), you have to take apart the unit.

Follow this guide in case that has happened to you.

Image 1/3: The metal plate slides forward as shown in the first picture. Image 2/3: 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 ([guide|12405|using this guide]).

  • 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.

I started folowing this guide but after step 3 my CD looked different:

I removed the PH screw and tied the white plastic ring. Tried to remove it but it didn't came out: the hole was too small. So I lowered it in the drive and thus gained access to the lens:

It was quite backwards than that in this manual:

I have the same problem. I couldn't remove the white plastic ring because the hole was too small. So I have a few questions.

1. Did you have problem with removing the screw (holding the white plastic ring)? Because I wasn't able to do this.

2. How did you separate this metal part from the white plastic ring? Is it necesary to tie the white plastic ring?

3. In the picture where there is the white plastic ring, I see a CD in the CD drive. While you were moving the white plastic ring to the left side a CD was still in the drive?

4. Does the RNS-D work after that operation?

Sorry for my english, I hope you will reply.

Finally I found why there is a difference: my unit is the older version known as RNS-C. Part number is 8D0 035 192 C. Main difference is that device works only with NON DX CD ROMs. So cleaning will not help: such disks are not available long time ago and there are no images of them on the web

It turned out that my unit is the older version, so called RNS-C. That is why it is different from that repair guide. It will read only NON DX CD's

Later units will work with both DX and NON DX Travelpilot CD ROM's

Image 1/1: Make sure that there is no dust on or near the player and area you are working on. Dust can get on the lens and scratch it while you are cleaning. It is very important that the lens is not damaged because the lens is used to read the discs.
  • Locate the lens inside the CD-ROM drive.

  • 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

This is a very common thing in a car and it happens if you have stopped commuting through your car. once go through the manuals of your CD drive and the lens cleaning process is certainly a very smooth work and more precautions are needed for this process .otherwise you can go the nearest repairing center. once my old car shown this type of problem and i tried to fix myself but failed so i took my car to the http://germanautospecialist.net/ expert Audi repairing center in thousand oaks,CA . I was fully satisfied by their expert service and reasonable price for repairing.
