I am driving a 2004 MC with the stock radio installed. I am attempting to connect my iPhone/iPod as well as my Xm portable. DICE appears to have ipod control as well as an AUX input for the XM. few questions...

-How difficult is the DICE to install?
-How are the steering wheel controls in regards to the iphone/ipod.
-Will i need to purchase any extra cables with this unit or will it come all included in ther package?
-Is it worth the extra money worth spending to have the control over the ipod or should I just spend the $50 on the aux audio cable and run it through the 1/8 inch input?

Any help is appreciated. Thanks!
