Depending on where you put the cable. Pulling out the head unit is easy, maybe takes a min. Search for my name and aux cable, and you will see where I put mine. That took some extra time because I had to bend my AUX plate.

Intravee II, IMHO.

Aux input mounted in glove box, flashlight power adapter and Griffin Technology Bluetrip AUX. Cool as all get out.

Get the DICE w the bluetooth. Mine works flawless.

Is there a difference in sound quality if I use the the headjack as a input source or the the bottom part of my iphone? Not sure what you call that input.

Where are you guys buying the aux cable? Cheapest ive seen is like $70

Dealer. Ecstuning.com, or Craig at BMW of Bloomfield.
