I am about to sell my 20GB unit, but before I do, I'd like to find out if there is any way to use it in my '07 BMW 530xi. I originally had it in my 1997 538i, but I'm told the interface is fiber optic in my 530, so it is not compatible. Does anyone know if there's a hack for that? I really love this unit and would like to be able to access the 500+ songs on it. Any help would be appreciated.
As far as I know, there's no i-bus to MOST adapter. And it would get pretty funky if there was, since the BMW Phatbox uses an adapter box to get to i-bus in the first place.
When I looked into this (I was going to import an out-of-market M5 Touring), there was a USB option available for the BMW. You should be able to put your music on a USB device (either a hard drive or a memory stick, since you only have a 20GB DMS) and play it directly from the head unit. You won't get audio announcements like the PhatBox does, but you do get direct browsing with all track info shown on the screen.
