Hi guys,

I just upgraded my system to MKIV in my 4.6is. The display now shows the option "Code". What is this for? Also, I swapped the radio module to a newer one so I can do XM Radio. I thought this would also give me the Aux Input (even though the wiring isn't in place for it yet) but I don't see this option on the screen. Does this only show up once the wiring is in place??

Thx
