Yep, ICT user interface is completely different, that's software.So you are saying that JLR wrote two completely different pieces of software for their cars, eventhough most of the functionality is the same? I don't buy it. It doesn't make any sense to do that.
The hardware control modules in the background are different, that's hardware and software.
The screen is different, with physical buttons, that's hardware and different control software.
The physical screen buttons also differ in function and operation between Markets...
Some of those software modules may well be the same between ICT and ICTP but not the whole system.
