Scirocco Central

Hi all, I don’t know if this is the right place to post but I’m after a little help please my discover media gen2 headunit might need the firmware updating that’s what I’m told. The problem I’m now experiencing is that the DAB keeps losing signals few months ago it was good but now this past month it has gone really bad and I’m told that it sounds like I might need to update the firmware? Is there any where I can download the latest firmware from as I can’t find it on the downloads page on the VW website ? I can only find the map updates on there. Any help appreciated
