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 indicatorLED on it) but will not play audio. When USB is connected to Gateway, it starts to index the contentimmediately (LED on the USB is flashing constantly) in order to find and select the tracks as quickly aspossible. If a large music content is available (4GB or above) it may take a few minutes during whichthe drive cannot be accessed, so playback might not be available, or when the user changes the musiccontent 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 thesystem 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 themusic files same way as the Gateway, but faster
