That's an unacceptable excuse, you put the GPS and radios in the unit. That's like going to buy some modern update to
an old car that puts a new transmission in it, but then when asked where the gearshift is you get told that you have to
go open the front hood and find some magic buttons to switch gears!!!
All you have to do is put the equivalent of a 'KingAir' autopiliot panel in the thing, there is even room on the panel on
top of the GPS unit itself.
I do not understand why this was not done.
