I like the idea of BMW assist but didn't end up with those options.
I have enhanced bluetooth in our other car and found I didn't stream audio much at all.
If you opt out of this like I did, pick up a cheep small Flash drive and lode your songs on it. This will take up no space in your arm rest compartment and you can just leave it there until you want new music.
This one will set you back a whopping 12 bucks.
The file browser works great through idrive and you don't have to mess with wires / charging / streaming.
Bluetooth works fantastic so no worries there either.
