Does anyone know how I can get the software updated on my Beosound 4?  I know it is supposed to be done by the dealer, but if I took a Beosound 4 to today's B&O dealers, they'd probably not even recognise it! Reason I ask - I bought an ML Gateway a little while ago as part of a few things bought as a kit.  I was going to sell it as I thought I had no use for it, but then learned (from a helpful reply to say to enter the Customer Service menu you should go into the menu, and then while Connections is highlighted, hit Red+Go to enter that menu.  I've tried that but nothing happens when I press Red+Go.  My BV8 software is up to date.
