I'm clear on the fact that an rns-e unit can be put into almost any allroad. my ? is how new of a unit can be put into how old of an allroad? what options will and won't work? DVD or usb maps? street(road)mph on map? i pod, Sirius compatible? still play Cd's?, reverse camera? play DVDs?
steering wheel controls?, center dash unit compatible?
i know that this is poberley explained on multiple forums but can i get a complete explanation in one place(here)?

side ? do allroads have a heated steering wheel as an option?
and how do you know which units with just a cursory look have Bose and which don't?

thanks all
