Troubleshooting Guide for Installing Dension Products

K. iPod/iPhone not recognized

This usually happens if there is a problem with the iPod / iPhone or Dock cable. Before replacing

anything, you need to try the following:

 Make sure there is music on the Apple device

 Reboot the Apple device (if it is an iPhone, close all apps before rebooting)

 Update the iPod/iPhone if a newer iOS version is available

 Check the charging status. If there is no charging the problem might be installation related

(no ground cable connected on VW/Audi)

 Test the system with a different Apple product

 Disconnect and reconnect the Gateway hardware from the power

 Check the Dension website. There might be an available update for the Gateway

L. USB compatibility

We recommend the use of branded USB drives (TDK, Kingston, Sandisk, Transcend etc.).

M. USB does not work/Gateway does not see the connected device:

In some cases the USB drive will only flash continuously or flash just once (if there is a status indicator

LED on it) but will not play audio. When USB is connected to Gateway, it starts to index the content

immediately (LED on the USB is flashing constantly) in order to find and select the tracks as quickly as

possible. If a large music content is available (4GB or above) it may take a few minutes during which

the drive cannot be accessed, so playback might not be available, or when the user changes the music

content on the USB the Gateway might not find the previously indexed songs.

So, if there is a problem with the USB playback, do the following:

- wait for a few minutes, then the playback should start

- turn the system OFF, remove the key from the ignition, wait for 2 minutes, and turn the

system back ON – the playback should start immediately

- delete all ‘.bin’ files from the root folder of the USB drive (the index files might be damaged)

- download the ‘Gateway Indexer software’ (Windows only) from our website. It indexes the

music files same way as the Gateway, but faster
