Updating Navigation Data

Procedure 

A SD-CDA card with at least 8 GB is needed for the Discover Media navigation data update. Volkswagen recommends the use of a special SD-CDA card with 8 GB for Discover Media, which is available through Volkswagen dealerships.

When installing the navigation data, it is important to follow the instructions for the vehicle. During the copying process the ignition must remain ON with the navigation function unavailable. Due to the large amount of data and depending on the SD card used, the update process can take up to four hours. Make sure a battery maintainer is attached when performing the update to avoid low voltage conditions. If the voltage drops too low, the update can fail.
