Does the current (2011) S550 hard-drive navigation program work in all W221 model years? I have a 2009 S550 and want the ability to dial a restaurant/business directly from the navigation screen - and not have to separately dial it from my bluetooth-connected phone.

If so, does this mean I must update/upgrade the entire COMAND software?

If anyone has done it, what did it cost and was it trouble-free?

The hardware is different on the facelift. They changed from NTG3 to NTG3.5 which is more like the NTG4 on a W204. NTG3.5 SW on an NTG3 unit would not work.
