Not in B7 but I did something similar to my e46. Unfortunately, I have a symphony II system with cassette player so this is not a mod I can do until I get symphony II+ or after market head unit.
Here is what I have done in my e46.
USB:
Buy a small cigarette lighter charger, cut the cover (just to remove the connectors to cigarette lighter port) and leave the wires connecting to the circuit board and top part with USB port intact, Remove the glovebox, make a hole, tap an empty slot at fuse box and connect it to the wires at the charger, attach the USB charger to the hole you made in the glovebox.
Aux:
Buy a 3.5mm female receptor at radioshack, connect the TRS of the 3.5mm female jack to the aux out wires to the head unit, make a hole in the glovebox, attach the 3.5mm female jack to the glovebox.
Buy cable for the iPhone/droid whatever:
A cable that uses one single port from the phone, and splits into USB and aux (3.5mm male), connect the ends to the USB and aux ports you just made in the glove box.
Something like this:

You have flexibility of a separate aux device and charging another device at the same time or charge and run aux in from the same device with a single cable. Cable stays in the glovebox when not in use.
Moreover, the audio signal coming from the charging port is line level on the iPhones so audio is much better than using the headphone jack.
