Hi Ben.
Not sure on the first question but I do know the second.
If your radio is the 6006, then it has a spare socket at the back for a special cable Ford make. It costs about £8.00 and connects to the back of your radio and the other end is a female headphone jack. This is supposed to be fitted next to the gear lever (requires drilling) but I have wedged it at the side of the centre compartment. Indeed, it runs to the AUX setting and it has made me very happy!!!
