I'd like to purchase this item for my 2002 X5 with NAV, without DSP.

All features of this kit are compatible with my vehicle, correct? (bluetooth, steering wheel controls, etc...?) What is the difference between the front and rear mount? Just where the box is located? Wouldn't most folks want front mount, otherwise you'd have to run an iPhone cable the whole way to the front of the vehicle?

Also, is the iPhone docking cable an apple product? I am using the Otterbox Defender case on my iPhone, which has a slim opening for a cable to plug in. The apple cable works, but most aftermarket cables do not.
