91 Navigation plus (RNS-E): Portion of DVD not readable, circular scratches
Condition
- The navigation system has reduced functionality.

Technical Background
Figure 1:
Under certain conditions, the drive mechanism may contact the DVD which is damaged as a result.
Production Solution
Drive mechanism improvements are under development.
Service
Test the drive mechanism by inserting a blank CD. When a DVD or CD is inserted, the Table of Contents (TOC) data on the inner-most track is read first.
Inserting the test CD several times should be sufficient to reproduce the problem. In most cases, the initial damage can be detected after the first time the blank CD has been inserted. This test can be performed any number of times.
- If circular scratches can be seen on the blank (test) CD, both the navigation unit and the DVD need to be replaced.
- If there is no damage to the blank (test) CD, only the DVD should be replaced.
Warranty
When procedure applies to vehicles under warranty, use the table.
Required Parts and Tools
Navigation DVDs can be purchased directly from Navteq.
