My 1M is loaded (except for hk) and for what its worth the only options I really am glad I have are the bluetooth, ipod/usb and comfort access. That said I do like the Nav screen, but only for the ipod interface and telephone. I don't really need navigation and when I do I find the iphone to be much more useful honestly.
I find the standard sound system lackluster though. If you like music I would upgrade to the HK system.
