I think the Y-adapter is archaic. I could maybe see it as something needed when iPod integration was new. But I haven't seen any other cars that use anything but a normal USB cable. Even a cheap aftermarket HU will simply use a normal USB connection.
And burying 'enhanced usb' functionality in the 'BMW Assist' option is bizarre. Now I'll more than likely need to attempt a combox media retrofit (since I can't seem to let it go lol). Still waiting to hear back from Alekshop on my query there.
Yeah Satellite radio is like low bitrate mp3, but at least the stations are decent. I never listen to FM radio - just CDs and the lossless music on my iPod.
